Working Smarter with Power Plant Dumb Terminals

After the reorganization at the coal-fired power plant in North Central Oklahoma during 1987, a bunch of new faces showed up at the plant. I mentioned in last week’s post that we had a new plant manager, Ron Kilman (See Post: “From Pioneers to Power Plant Managers“). In that post I also mentioned that the PC age was rapidly growing and I had bought a computer of my own and was eager to learn more. The Electrical Supervisor, Leroy Godfrey had retired, and was replaced by a guy named Tom Gibson. Tom was a good supervisor who was willing to think out of the box.
Tom gave me one of my first assignments directly by calling me to his office. Well, Leroy had never really called me to his office before. When Leroy wanted to chew you out, he was happy to come down to the Electric Shop and do it, so I didn’t really know what to expect by being “called to his office”. Believe me… it wasn’t the last time he had “called me to his office.” But it was the most satisfying time. Mainly because this time, when I arrived, Tom’s face wasn’t beet red with anger like it was on one later occasion (See the post Power Plant Customer Service Team Gone Wild).
This is what Tom told me to do… He said that we needed to install computer terminals all over the plant. They had a chart where they wanted the terminals to go. There were about 15 locations and about 30 terminals all over the plant including the coalyard which was about 1/2 mile from the main plant. Along with those, there were a bunch of IBM Network printers that needed to be installed with the terminals.
Then Tom told me the best part. He wanted me to do it all myself. Then he told me an even better part…. He said, (and I quote) “I want you to learn everything you can about this computer stuff. I think it will come in handy.” As my friend Stephen Todd at Dell would say, “That was the ‘Keys to the Kingdom”. I told him I would be glad to do everything he asked.
That last part later came back to haunt Tom…. but he did tell me…. learn “everything” I could about the computer. When he was referring to “The Computer”, he was talking about the company mainframe, a Honeywell system that resided in Oklahoma City at Corporate Headquarters.
A Honeywell Mainframe computer
The Terminals I was going to install were called “Dumb terminals”. they weren’t computers, they were just monitors with a keyboard that connected directly to a switch back in the telephone room that was connected via a microwave link directly to Oklahoma City and the Honeywell system:
A DEC terminal like this.
So, when I returned to the electric shop, I began my “hacker” apprenticeship. One that would later allow me to harass Gene Day in the Control Room, confuse Dick Dale in the warehouse, cause headaches for the IT department downtown, and finally cause the President of the Electric Company to personally call our Plant Manager Ron asking who was this guy Kevin Breazile! Hence the reason for Tom Gibson’s beet red face a few years later. But that is another story for another time.
I had two things right away that I had to figure out. How was I going to run cables from the telephone room in the office to each of the places around the plant that needed a computer terminal and what are these funny connectors and what do I need to do with them?
A Modular DB25M to RJ45 Adapter
Ok, so I figured they plugged in the back of the terminal and then there was a Cat1 cable (no, not a Cat3, a Cat1) that plugged into that, and needed to plug into a jack in the wall that I was going to have to install. They called these funny connectors “Hoods”. The 25 pin Hoods that we used were blue. We had 9 pin hoods also that we used for the actual PCs that the clerks and the chemist were using. They had an emulator program to make them act like a dumb terminal:
A Serial RS232-DB9 9-Pin Female to RJ45 Adapter
In an early post called “Power Plant Men’s Club Prizes and a Story of Luck” I explained how I have always been cursed with being very lucky. Well, that’s what some may call it, but I prefer to believe that one of my best friends St. Anthony helps me out at certain times. Well, this was one time when I asked for his assistance. St. Anthony of Padua is considered the Patron Saint of lost items. So, I asked him to help me figure out how I was going to do all this work in a reasonable amount of time.
St. Anthony of Padua
As is often the case, St. Anthony pointed me in the right direction. This particular day, he told me to tell my problem to Charles Foster. My close friend and one of the two Electric Shop foremen (not mine. I was working for Andy Tubbs). So, during lunch I told him what Tom Gibson told me to do, and showed him the blueprints where they wanted the terminals placed throughout the plant.
One of the places that needed a terminal was right there in the electric shop office. Charles looked around the office and said, “You know what? there used to be an old intercom system in this office that I think goes up to the telephone room. In fact, I think all the intercoms that were originally installed in the plant went to the telephone room.”
An old intercom sort of like this only older and in a box that sat on the desk and it had more switches
I vaguely remembered the intercoms when I was working as a summer help as there used to be an old box sitting in the garage when I worked for Stanley Elmore. They were later cut out and removed, because it wasn’t really practical and so it wasn’t used. Charles told me to start there, because there were intercoms everywhere. In the control room, the warehouse, and even in the coalyard! And definitely in the office area. This was just what I needed to hear. My work was already half done.
I pulled the cables out from under the desk where they had been cut and checked them out. There were definitely enough cable pairs to do the job. In most places I had to install both a terminal and a printer, so I had a lot of dual wall jacks just for this job:
A dual RJ45 Wall Jack
There were some places where the intercom system didn’t go where I needed to install either a dumb terminal or at least connect a computer. So, I was looking for any kind of alternate way to install the jack without having to run cables all the way from the telephone room to these locations. So, I went out and bought a book about networking so that I could learn more about what was really going on. If I had bought it a few years later it might have been called “Dumb Terminals for Dummies”, but the Dummies books hadn’t come around yet.
I have since thrown that book away after using it for years to prop up the corner of our sofa bed for the times when my mom would come and visit and she would sleep on the bed, only it had a broken bracket, and the Networking book was just the right thickness to level the bed…. But there was one page in the book that I found that allowed me to hook up dumb terminals in places where there was only a phone line.
You see. When the phone lines were run throughout the plant, they used a three pair cable. Well. A phone really only uses two wires (or one pair). so, this left 4 more wires not doing anything. The only problem was that the dumb terminal used 4 pair, or 8 wires…
An RJ45 Cable has 8 wires
So, when I was reading the networking book, I ran across a diagram that made me stop and stare. I like to think that I was holding a half eaten apple in my hand and I had just taken a bite when I stopped mid-bite and stared. It would have been a nice picture to remember sort of like when the apple fell on Newton’s head. Only we didn’t have cellphones with cameras in those days, so no one was around to take my picture. The diagram I saw was this:
The pin configuration for an RJ45 connector
What? This showed 4 of the wires are nothing but grounds…. The network cable only really uses 4 of the 8 wires. Which means I only needed two pair. And guess what? The phone lines run all over the plant were 3 pair with only one pair being used! So, I was able to install the computer jacks right next to the telephone jacks and use the same cable that the telephone was using, and they all tied back to the telephone room where the main computer switch was located that connected to the Mainframe computer back in Oklahoma City through something called a Memotec X.25 Modem.
So, now that I have gone through all this detail to tell you how I was able to quickly install all these terminals and printers around the plant in a way as if it is exciting (because it is to me). I know that many of you are so bored out of your gourd that you have already stopped reading before you have reached this sentence…. I suppose those of you that are still following along are wondering “Why?”
Why would we want to install all these dumb terminals throughout a power plant that connected to the Honeywell Mainframe down at Corporate Headquarters? Well. It was because all the plant operators, mechanics, welders, machinists, electricians, instrument and controls and heavy equipment operators were going to start using it to do stuff. Yeah. All of us were being introduced to the computer age. From the janitor on up.
Each printer had 5 character ID that identified it, so if you were looking at a work order on the terminal, you could choose to print it. You just had to know the 5 character number and you could print the work order out on any computer in the company. Usually, this meant, you wanted to use the printer that was closest to you. But if you wanted to print something out for the warehouse, as long as you knew their printer ID, you could send them a printout of some part that you wanted them to retrieve for you. Then call them up and tell them you printed something out on their printer.
Ok. So the average Joe didn’t see much benefit, but it did get them used to seeing computer monitors all over the place, which at least helped them in the future when the real computers showed up. Right now, they were just “Dumb Terminals” and that’s what a lot of the operators and maintenance people thought… they are just dumb…
I, on the other hand was in hog heaven. You see. I had called downtown to the IT department and asked to get a user name so that I could log directly into the mainframe. After all, my supervisor Tom had told me to learn “everything” I could about “this computer”. So, I took him up on it. I quickly was learning UNIX commands, though at the time, I didn’t know that’s what they were called.
I began learning the Computer language called “A” before I realized there was a “B” language and a “C” language, and that C was the one that was really used at the time. As it turned out the mainframe had manuals for everything right on it. That is how I was able to cause so much trouble the next few years.
Oh, and one more interesting thing I discovered on the mainframe. It had this interesting feature called “Email”. Yeah. Only, after figuring out how to pull up a list of all the emails on the system I found that there was only a handful of people that actually had e-mail addresses. So, the only person I would email on the mainframe was an engineer named Craig Henry.
Craig Henry. Engineer and Gentleman
I had met him briefly once, but in the next few years, he was a valuable source of information. Email seemed like a great idea, but what good was it if there was only a few people you could send an email?
As for Craig Henry… As Humphrey Bogart said to Claude Rains in Casablanca, “This is the beginning of a Beautiful Friendship.” Come to think of it… Craig Henry sort of reminds me of Claude Rains… I must admit, I learned a lot more from him than he ever learned from me.

I never would have guessed that playing Power Plant Man jokes on Gene Day would have led me to the “Uh Oh!” moment I later encountered when I was told in no uncertain terms that the President of the Electric Company, James G. Harlow Junior was personally upset with something I had done. I had learned my first year as a summer help at the coal-fired Power Plant in North Central Oklahoma that “One ‘Uh Oh’ wipes out all previous ‘Atta Boys’!” I could tell by the way the Electric Supervisor, Tom Gibson’s ears were glowing red that this was considered a little more serious than I had first realized.
I have mentioned in previous posts that playing jokes on Gene Day was one of my favorite Power Plant Man Pastimes. See the post, “Power Plant Humor and Joking With Gene Day“. Also see, “Psychological Profile of a Power Plant Control Room Operator“. My lunch breaks were usually consumed with learning more about how to program the Honeywell mainframe computer used by just about all the company processes that actually ran the company from payroll, to billing, to work orders and Inventory. I figured that as I learned more about the computer system, the more elaborate jokes I would be able to play on Gene. That was my ultimate motivation.
Already I had learned about the escape codes used by the large IBM printers that were used throughout the company at the time. This allowed me to create graphic images on the printer as well as large bold letters.
IBM Dot Matrix Network Printer
Besides the telephone and inter-company mail, printers were the only other way to communicate to non-present Power Plant Men in 1989. We had not yet been introduced to e-mail. I was one of the few people in the company that had an e-mail address on the mainframe, and the only other person that I knew that I could write to was Craig Henry, a Corporate Engineer downtown.
Craig Henry. Engineer and Gentleman
Much like the first time when I met Gene Day, when I first encountered Craig Henry, I could tell right away that he was a down-to-earth person that would shoot straight. Craig probably wouldn’t remember this far into the past that I would reach out to him occasionally just to say “Hi” and to pick his brain about how the corporate IT infrastructure was setup. I figured since he was one of the few people in the company that even knew what an e-mail address was at the time, he most likely had more knowledge about such things than the average person in Corporate Headquarters.
After finding out that Gene Day would go work out at the Rock Gym in Stillwater, Oklahoma after work, and I had played the joke on him with the notes from the private investigator, I used my knowledge of Printer Escape codes to write documents on the mainframe that when printed out would turn on the graphic commands on the printer so that I could print out pictures. I don’t mean that I would have a saved picture that I would send to a printer like we might do today. No. I had to create these pictures one pixel at a time using commands in a UNIX document on the mainframe. It was all codes that would not make sense to anyone that didn’t know the graphic commands of the IBM printers.
I had been teasing Gene Day about meeting up with a young “coed” from the University at the Gym each day. I would do this by printing out messages on the Control Room printer by the the Shift Supervisor’s office when I knew that Gene Day was there filling in as the Shift Supervisor. They were usually notes from someone that called herself “Bunny”. Usually they were short notes or “love letters” from Bunny just saying something about how she enjoyed her time with Gene at the Gym.
At the bottom I would sign it “Bunny” then under it, the printer would read the graphic commands and create a small Playboy Bunny symbol under the name. At the end, the document would send a command that would put the printer back into the text mode.
Of course. Whenever I walked into the control room shortly after, just to see how the precipitator was doing, Gene Day would confront me about the notes. With a grin on his face he would say, “This isn’t funny! What if my wife found one of these notes?” — Like that was ever going to happen…. unless he was like me, and likes to save everything.
Note to Gene Day from Bunny (now she knows)
In order to create the bunny at the bottom I had to create the pixels in small blocks of 9 pixel patterns. Here is the code I used to create the bunny:
See? I save everything
In the last couple of weeks I have written about how the Power Plant Men were introduced to the “Quality Process” (otherwise known as “Six Sigma”). We had created teams with our crews and we met once each week to come up with Quality ideas. By August, 1993, I had received my official Certificate Certifying that I had completed all the QuickStart training and was on my way to making a difference in the Power Plant World!
My Customer Service Team Certificate. This made me official!
So, what do these two events have in common and how did this lead the President of the Electric Company to send out a search warrant on a lowly (lowlife is more like it) Plant Electrician in North Central Oklahoma? Well. This is what happened…
First you have to remember that in 1993, the Internet was not easily accessible by the general public. Company e-mail was still not a reality in our company. We had dumb terminals and large IBM printers. That was the extent of most employees interaction with a computer. Each printer had a designation. It was a five character ID beginning with a “P”. So, the printer in the Electric Shop Office might be…. P1234. I needed to know this number if I wanted to send something to it.
At the time, the only thing people had to send to each other were requests for things from the mainframe systems that were used to run the company. So, for instance, if you wanted to request some parts from the warehouse at our plant, we would send over a list of parts to the warehouse printer where Dick Dale and Darlene Mitchell would pick it up and go retrieve the parts. So, the people that used the terminals and computers with mainframe emulators on them knew the most commonly used printer numbers in the plant.
If you wanted to send something to someone in Oklahoma City, or to the Power Plant in Muskogee, then you would have to call over there and ask the person what their Printer ID is so you can be sure you are sending your request to the appropriate printer. Without e-mail, and any other form of computerized communication. This was the only way at the time.
So, after our Customer Service Team was formed, we would meet once each week to brainstorm new ideas that would benefit the company. Andy Tubbs was our team leader, as he was our foreman.
Andy Tubbs – True Power Plant Electrician
The other members of our Customer Service Team were Diana Brien, Scott Hubbard, Sonny Kendrick, Ben Davis and Gary Wehunt. I haven’t properly introduced my bucket buddy Diana Brien in a post before. I have recently obtained a photograph that I can share:
My Bucket Buddy Diana Brien
We were called bucket buddies because we carried tool buckets with us whenever we went to work on something. They doubled as our stool and tripled as our trash can.
Thursday, July 15, 1993 during our Quality Brainstorming session, while we were pouring out ideas like…. “What if we changed out the street lights at the plant so that they would be different colors…. wouldn’t that help morale?…. and “How about if we wrapped fluorescent Christmas lights around the high voltage electric lines between here and Oklahoma City so that they could light up the night with colorful lights during the Christmas Season?”….. And other ingenious Brainstorming ideas that are bound to pull up an occasional brilliant idea….. well. One such idea popped up!
I don’t remember which one of our brilliant brainstorming ideas conjured up this idea, but Andy Tubbs suddenly blurted out…. “What if we had the Printer IDs added as a column in the Corporate Directory? — You see, each quarter we received an updated paper copy of the Corporate Phone Book. It included the names and office phone numbers of all the Electric Company employees. It also included their mail code. So, if you wanted to send something through inter-company mail to them, you would know where to send it. Our mail code was PP75. That was the code for our power plant.
So, what if we added a column where we had the printer ID that each person would use for people to send printed requests, among other things? This was Brilliant! We could just make this proposal and send it downtown to Corporate Headquarters where it would be lost in the “mail”. Or we could do more research to prove that it was a possible proposal that was really do-able.
So, I suggested…. Well… I can print a form out on every printer in the entire company requesting that they include all the names of all the people that use that printer and mail it through inter-company mail back to me at PP75. — I had recently uncovered a special printer command that allowed me to do this hidden away on the Honeywell mainframe. So, we took a vote and it was decided that we would pursue this proposal. I set to work on creating the form that I would send to every printer. If we could not only send the proposal to the Communications department downtown, but also a list of everyone and their printers, the work would already have been done for them.
I wanted to send a real fancy letter because I had already created a header using the Quality print settings on the printers. I had created a Company Logo that (I thought) ingeniously used the backspace command to create two words with one word on top of the other in the middle of a sentence…. Our company began as Oklahoma Gas and….. in the logo, I wanted the word Gas to be on top of the word And as it was in our company logo in smaller letters than the others. So… after playing around with it for a while, I created the logo and had it saved on the mainframe.
I know. I was rotten to Gene Day. Here is an example of the header with the “GAS AND” in the middle of the name. Remember. This is on an old IBM Dot Matrix printer using the High Quality setting
After attaching the header to the form, I included a message that told the person that discovered the form on the printer to add the names of all people who used the printer below and to send the form to Kevin Breazile at PP75. As I mentioned. In order to make the form look pretty, I turned on the Quality Print settings on the printer at the beginning of the document. Like the story of the Sorcerer’s Apprentice….. I didn’t know a good way to turn off all the settings I changed to revert the printers back to their original settings.
I ran the command to send the document to every printer on the print server and away they went…. A copy printed out on the printer in the Electric Shop office so I knew it was working. Copies printed out on the other 12 printers at our plant. They also printed out on the 500 other printers throughout Oklahoma. — With the thought that “My work here is done.” I went back to work repairing plant electric equipment.
The following Monday I had the day off. When I returned to work on Tuesday, Denise Anson called me from the front office. She said that I had a large stack of mail. I thought, “Oh good!” Results from our request on Thursday have arrived! I hurried up to the front office.
When I entered the mail cubicle I was surprised to see how big the pile of envelopes were. The stack of inter-company envelopes was over two feet high. “Um…. Thanks….” I said to Denise. I picked up the stack and headed back to the Electric Shop to sort out the forms.
After opening the first few envelopes. I suddenly came to an astonishing discovery. Not only did the form print out on the large mainframe IBM printers used in office areas, it also had printed out on other types of printers…. I opened one envelope and found the form printed out on a “Work Order” printer. The paper size was different than the standard paper size, and I hadn’t put a page feed at the end of the document, so, it had left the paper in the middle of the page…. “Uh Oh”.
My “Uh Oh” changed to “UH OH!” after opening a few more of the inter-company envelopes. I found that the form had printed out on Pay Check Printers! And Billing Printers! “UH OH!” quickly changed to “OH NO!” When I read comments like “Under no circumstances print anything on this Printer Again!!!!” I realized I had really messed things up. By changing the font size and the quality settings, the billing, payroll and work order printers all had to be manually reset and the jobs that printed out paychecks, customer bills and employee work orders had to be re-run!
After taking all the forms out of their envelopes, the stack of papers was over 4 inches thick, just to give you an idea about how many responses we had.
A couple of hours later, Tom Gibson called me to his office. “Uh Oh.” (remember… One “uh oh” erases all previous “atta boy”s). When I entered Tom’s office, I could tell that something was definitely wrong. Like I mentioned earlier. Tom’s ears were beet red…. and in case you don’t know what a beet looks like. Here is one:
The same color of Tom Gibson’s ears
Of course… I knew what this was all about, only I didn’t know yet, how Tom had found out about it…. Tom began by saying…. “Ron Kilman just received a call from James Harlow asking him who is Kevin Breazile and why is he printing something out on my printer? Ron didn’t like the fact that he wasn’t aware that you had sent something to the President of the Company’s printer.
James G. Harlow Jr.
Sorry. That’s the biggest picture I could find of James Harlow….
Um what could I say? So, I said this…
“Well. This was a quality idea that our team had. We wanted to collect the names of people that used each printer so that we could send in a proposal to have the printer ID added in the Corporate Directory.”
I didn’t mention that Harlow’s Secretary had returned the form with all the people that used his computer as I had requested, because I knew that the President of the Electric Company was not asking because he was upset that I had printed something out on HIS printer. No. He had probably been told that the reason the bills were late being sent to the one million customers that month was because some kook had messed up their printers and the jobs had to be run over again causing the delay. So, I thought it was best not to go down that route at this time…
So, I stuck with my story, which was the truth…. I had printed out the forms on all the printers as part of a quality idea by our CST (Customer Service Team). — I also didn’t mention that three years earlier, Tom had asked me to learn everything I could about the company computer, because he believe that the computer was going to be the wave of the future.
Even though Tom believed my explanation, he told me…. “Kevin, Ron never wants this to happen again, therefore, you are never to send anything out of this plant without Ron Kilman’s personal approval. Is that clear?”
I replied to Tom that this was unreasonable. I send things to other departments all the time. I send Substation Inspection forms, and blueprint revisions and all sorts of other forms downtown all the time. Ron Kilman wouldn’t want to waste his time approving all those things….
Tom thought about it and revised his statement…. “Then, don’t ever send out anything that isn’t part of your normal daily job without Ron’s approval first.” — Ok. I thought…. this works, since everything I do is part of my normal daily job…. Even printing out forms on all the printers in the company… since that was part of our normal “Quality Process” Customer Service Team activity…. So, I happily agreed. And I left Tom’s office happy that I hadn’t joined the ranks of the unemployed.
That was one thing about working at the plant at this time. As long as your heart was in the right place…. That is, you tried your best to keep the electricity humming through the electric lines…. then the chances of being fired for messing up, even as big of a mess up as this, most often didn’t end up by losing your job.
I sometimes think that this was my biggest mess up of all time… however…. after this episode was over… there was a part two to this story….. Believe it or not…. Someone else in the company was overjoyed about what I had just done. They had been trying to do something similar for a long time, only to be told that it was impossible. — Doing the Impossible… I was good at that… Part two of this story is a story for another day…
Since this is a repost of this story, I have written part two, which you can read here: “Printing Impossible Power Plant Fast News Post“.

Ok, so I figured they plugged in the back of the terminal and then there was a Cat1 cable (no, not a Cat3, a Cat1) that plugged into that, and needed to plug into a jack in the wall that I was going to have to install. They called these funny connectors “Hoods”. The 25 pin Hoods that we used were blue. We had 9 pin hoods also that we used for the actual PCs that the clerks and the chemist were using. They had an emulator program to make them act like a dumb terminal:
A Serial RS232-DB9 9-Pin Female to RJ45 Adapter
In an early post called “Power Plant Men’s Club Prizes and a Story of Luck” I explained how I have always been cursed with being very lucky. Well, that’s what some may call it, but I prefer to believe that one of my best friends St. Anthony helps me out at certain times. Well, this was one time when I asked for his assistance. St. Anthony of Padua is considered the Patron Saint of lost items. So, I asked him to help me figure out how I was going to do all this work in a reasonable amount of time.
St. Anthony of Padua
As is often the case, St. Anthony pointed me in the right direction. This particular day, he told me to tell my problem to Charles Foster. My close friend and one of the two Electric Shop foremen (not mine. I was working for Andy Tubbs). So, during lunch I told him what Tom Gibson told me to do, and showed him the blueprints where they wanted the terminals placed throughout the plant.
One of the places that needed a terminal was right there in the electric shop office. Charles looked around the office and said, “You know what? there used to be an old intercom system in this office that I think goes up to the telephone room. In fact, I think all the intercoms that were originally installed in the plant went to the telephone room.”

There were some places where the intercom system didn’t go where I needed to install either a dumb terminal or at least connect a computer. So, I was looking for any kind of alternate way to install the jack without having to run cables all the way from the telephone room to these locations. So, I went out and bought a book about networking so that I could learn more about what was really going on. If I had bought it a few years later it might have been called “Dumb Terminals for Dummies”, but the Dummies books hadn’t come around yet.
I have since thrown that book away after using it for years to prop up the corner of our sofa bed for the times when my mom would come and visit and she would sleep on the bed, only it had a broken bracket, and the Networking book was just the right thickness to level the bed…. But there was one page in the book that I found that allowed me to hook up dumb terminals in places where there was only a phone line.
You see. When the phone lines were run throughout the plant, they used a three pair cable. Well. A phone really only uses two wires (or one pair). so, this left 4 more wires not doing anything. The only problem was that the dumb terminal used 4 pair, or 8 wires…
An RJ45 Cable has 8 wires
So, when I was reading the networking book, I ran across a diagram that made me stop and stare. I like to think that I was holding a half eaten apple in my hand and I had just taken a bite when I stopped mid-bite and stared. It would have been a nice picture to remember sort of like when the apple fell on Newton’s head. Only we didn’t have cellphones with cameras in those days, so no one was around to take my picture. The diagram I saw was this:
The pin configuration for an RJ45 connector
What? This showed 4 of the wires are nothing but grounds…. The network cable only really uses 4 of the 8 wires. Which means I only needed two pair. And guess what? The phone lines run all over the plant were 3 pair with only one pair being used! So, I was able to install the computer jacks right next to the telephone jacks and use the same cable that the telephone was using, and they all tied back to the telephone room where the main computer switch was located that connected to the Mainframe computer back in Oklahoma City through something called a Memotec X.25 Modem.
So, now that I have gone through all this detail to tell you how I was able to quickly install all these terminals and printers around the plant in a way as if it is exciting (because it is to me). I know that many of you are so bored out of your gourd that you have already stopped reading before you have reached this sentence…. I suppose those of you that are still following along are wondering “Why?”
Why would we want to install all these dumb terminals throughout a power plant that connected to the Honeywell Mainframe down at Corporate Headquarters? Well. It was because all the plant operators, mechanics, welders, machinists, electricians, instrument and controls and heavy equipment operators were going to start using it to do stuff. Yeah. All of us were being introduced to the computer age. From the janitor on up.
Each printer had 4 character ID that identified it, so if you were looking at a work order on the terminal, you could choose to print it. You just had to know the 4 character number and you could print the work order out on any computer in the company. Usually, this meant, you wanted to use the printer that was closest to you. But if you wanted to print something out for the warehouse, as long as you knew their printer ID, you could send them a printout of some part that you wanted them to retrieve for you. Then call them up and tell them you printed something out on their printer.
Ok. So the average Joe didn’t see much benefit, but it did get them used to seeing computer monitors all over the place, which at least helped them in the future when the real computers showed up. Right now, they were just “Dumb Terminals” and that’s what a lot of the operators and maintenance people thought… they are just dumb…
I, on the other hand was in hog heaven. You see. I had called downtown to the IT department and asked to get a user name so that I could log directly into the mainframe. After all, my supervisor Tom had told me to learn “everything” I could about “this computer”. So, I took him up on it. I quickly was learning UNIX commands, though at the time, I didn’t know that’s what they were called.
I began learning the Computer language called “A” before I realized there was a “B” language and a “C” language, and that C was the one that was really used at the time. As it turned out the mainframe had manuals for everything right on it. That is how I was able to cause so much trouble the next few years.
Oh, and one more interesting thing I discovered on the mainframe. It had this interesting feature called “Email”. Yeah. Only, after figuring out how to pull up a list of all the emails on the system I found that there was only a handful of people that actually had e-mail addresses. So, the only person I would email on the mainframe was an engineer named Craig Henry.
Craig Henry. Engineer and Gentleman
I had met him briefly once, but in the next few years, he was a valuable source of information. Email seemed like a great idea, but what good was it if there was only a few people you could send an email?
As for Craig Henry… As Humphrey Bogart said to Claude Rains in Casablanca, “This is the beginning of a Beautiful Friendship.” Come to think of it… Craig Henry sort of reminds me of Claude Rains… I must admit, I learned a lot more from him than he ever learned from me.
Power Plant Customer Service Team Gone Wild

I never would have guessed that playing Power Plant Man jokes on Gene Day would have led me to the “Uh Oh!” moment I later encountered when I was told in no uncertain terms that the President of the Electric Company, James G. Harlow Junior was personally upset with something I had done. I had learned my first year as a summer help at the coal-fired Power Plant in North Central Oklahoma that “One ‘Uh Oh’ wipes out all previous ‘Atta Boys’!” I could tell by the way the Electric Supervisor, Tom Gibson’s ears were glowing red that this was considered a little more serious than I had first realized.
I have mentioned in previous posts that playing jokes on Gene Day was one of my favorite Power Plant Man Pastimes. See the post, “Power Plant Humor and Joking With Gene Day“. Also see, “Psychological Profile of a Power Plant Control Room Operator“. My lunch breaks were usually consumed with learning more about how to program the Honeywell mainframe computer used by just about all the company processes that actually ran the company from payroll, to billing, to work orders and Inventory. I figured that as I learned more about the computer system, the more elaborate jokes I would be able to play on Gene.
Already I had learned about the escape codes used by the large IBM printers that were used throughout the company at the time. This allowed me to create graphic images on the printer as well as large bold letters.
IBM Dot Matrix Network Printer
Besides the telephone and inter-company mail, printers were the only other way to communicate to non-present Power Plant Men in 1989. We had not yet been introduced to e-mail. I was one of the few people in the company that had an e-mail address on the mainframe, and the only other person that I knew that I could write to was Craig Henry, a Corporate Engineer downtown.
Craig Henry. Engineer and Gentleman
Much like the first time when I met Gene Day, when I first encountered Craig Henry, I could tell right away that he was a down-to-earth person that would shoot straight. Craig probably wouldn’t remember this far into the past that I would reach out to him occasionally just to say “Hi” and to pick his brain about how the corporate IT infrastructure was setup. I figured since he was one of the few people in the company that even knew what an e-mail address was at the time, he most likely had more knowledge about such things than the average person in Corporate Headquarters.
After finding out that Gene Day would go work out at the Rock Gym in Stillwater, Oklahoma after work, and I had played the joke on him with the notes from the private investigator, I used my knowledge of Printer Escape codes to write documents on the mainframe that when printed out would turn on the graphic commands on the printer so that I could print out pictures. I don’t mean that I would have a saved picture that I would send to a printer like we might do today. No. I had to create these pictures one pixel at a time using commands in a UNIX document on the mainframe. It was all codes that would not make sense to anyone that didn’t know the graphic commands of the IBM printers.
I had been teasing Gene Day about meeting up with a young “coed” from the University at the Gym each day. I would do this by printing out messages on the Control Room printer by the the Shift Supervisor’s office when I knew that Gene Day was there filling in as the Shift Supervisor. They were usually notes from someone that called herself “Bunny”. Usually they were short notes or “love letters” from Bunny just saying something about how she enjoyed her time with Gene at the Gym.
At the bottom I would sign it “Bunny” then under it, the printer would read the graphic commands and create a small Playboy Bunny symbol under the name. At the end, the document would send a command that would put the printer back into the text mode.
Of course. Whenever I walked into the control room shortly after, just to see how the precipitator was doing, Gene Day would confront me about the notes. With a grin on his face he would say, “This isn’t funny! What if my wife found one of these notes?” — Like that was ever going to happen…. unless he was like me, and likes to save everything.
Note to Gene Day from Bunny (now she knows)
In order to create the bunny at the bottom I had to create the pixels in small blocks of 9 pixel patterns. Here is the code I used to create the bunny:
See? I save everything
In the last couple of weeks I have written about how the Power Plant Men were introduced to the “Quality Process” (otherwise known as “Six Sigma”). We had created teams with our crews and we met once each week to come up with Quality ideas. By August, 1993, I had received my official Certificate Certifying that I had completed all the QuickStart training and was on my way to making a difference in the Power Plant World!
My Customer Service Team Certificate. This made me official!
So, what do these two events have in common and how did this lead the President of the Electric Company to send out a search warrant on a lowly (lowlife is more like it) Plant Electrician in North Central Oklahoma? Well. This is what happened…
First you have to remember that in 1993, the Internet was not easily accessible by the general public. Company e-mail was still not a reality in our company. We had dumb terminals and large IBM printers. That was the extent of most employees interaction with a computer. Each printer had a designation. It was a five character ID beginning with a “P”. So, the printer in the Electric Shop Office might be…. P1234. I needed to know this number if I wanted to send something to it.
At the time, the only thing people had to send to each other were requests for things from the mainframe systems that were used to run the company. So, for instance, if you wanted to request some parts from the warehouse at our plant, we would send over a list of parts to the warehouse printer where Dick Dale and Darlene Mitchell would pick it up and go retrieve the parts. So, the people that used the terminals and computers with mainframe emulators on them knew the most commonly used printer numbers in the plant.
If you wanted to send something to someone in Oklahoma City, or to the Power Plant in Muskogee, then you would have to call over there and ask the person what their Printer ID is so you can be sure you are sending your request to the appropriate printer. Without e-mail, and any other form of computerized communication. This was the only way at the time.
So, after our Customer Service Team was formed, we would meet once each week to brainstorm new ideas that would benefit the company. Andy Tubbs was our team leader, as he was our foreman.
Andy Tubbs – True Power Plant Electrician
The other members of our Customer Service Team were Diana Brien, Scott Hubbard, Sonny Kendrick, Ben Davis and Gary Wehunt. I haven’t properly introduced my bucket buddy Diana Brien in a post before. I have recently obtained a photograph that I can share:
My Bucket Buddy Diana Brien
We were called bucket buddies because we carried tool buckets with us whenever we went to work on something. They doubled as our stool and tripled as our trash can.
Thursday, July 15, 1993 during our Quality Brainstorming session, while we were pouring out ideas like…. “What if we changed out the street lights at the plant so that they would be different colors…. wouldn’t that help morale?…. and “How about if we wrapped fluorescent Christmas lights around the high voltage electric lines between here and Oklahoma City so that they could light up the night with colorful lights during the Christmas Season?”….. And other ingenious Brainstorming ideas that are bound to pull up an occasional brilliant idea….. well. One such idea popped up!
I don’t remember which one of our brilliant brainstorming ideas conjured up this idea, but Andy Tubbs suddenly blurted out…. “What if we had the Printer IDs added as a column in the Corporate Directory? — You see, each quarter we received an updated copy of the Corporate Phone Book. It included the names and office phone numbers of all the Electric Company employees. It also included their mail code. So, if you wanted to send something through inter-company mail to them, you would know where to send it. Our mail code was PP75. That was the code for our power plant.
So, what if we added a column where we had the printer ID that each person would use for people to send printed requests, among other things? This was Brilliant! We could just make this proposal and send it downtown to Corporate Headquarters where it would be lost in the “mail”. Or we could do more research to prove that it was a possible proposal that was really do-able.
So, I suggested…. Well… I can print a form out on every printer in the entire company requesting that they include all the names of all the people that use that printer and mail it through inter-company mail back to me at PP75. — I had recently uncovered a special printer command that allowed me to do this hidden away on the Honeywell mainframe. So, we took a vote and it was decided that we would pursue this proposal. I set to work on creating the form that I would send to every printer. If we could not only send the proposal to the Communications department downtown, but also a list of everyone and their printers, the work would already have been done for them.
I wanted to send a real fancy letter because I had already created a header using the Quality print settings on the printers. I had created a Company Logo that (I thought) ingeniously used the backspace command to create two words with one word on top of the other in the middle of a sentence…. Our company began as Oklahoma Gas and….. in the logo, I wanted the word Gas to be on top of the word And as it was in our company logo in smaller letters than the others. So… after playing around with it for a while, I created the logo and had it saved on the mainframe.
I know. I was rotten to Gene Day. Here is an example of the header with the “GAS AND” in the middle of the name. Remember. This is on an old IBM Dot Matrix printer using the High Quality setting
After attaching the header to the form, I included a message that told the person that discovered the form on the printer to add the names of all people who used the printer below and to send the form to Kevin Breazile at PP75. As I mentioned. In order to make the form look pretty, I turned on the Quality Print settings on the printer at the beginning of the document. Like the story of the Sorcerer’s Apprentice….. I didn’t know a good way to turn off all the settings I changed to revert the printers back to their original settings.
I ran the command to send the document to every printer on the print server and away they went…. A copy printed out on the printer in the Electric Shop office so I knew it was working. Copies printed out on the other 12 printers at our plant. They also printed out on the 500 other printers throughout Oklahoma. — With the thought that “My work here is done.” I went back to work repairing plant electric equipment.
The following Monday I had the day off. When I returned to work on Tuesday, Denise Anson called me from the front office. She said that I had a large stack of mail. I thought, “Oh good!” Results from our request on Thursday have arrived! I hurried up to the front office.
When I entered the mail cubicle I was surprised to see how big the pile of envelopes were. The stack of inter-company envelopes was over two feet high. “Um…. Thanks….” I said to Denise. I picked up the stack and headed back to the Electric Shop to sort out the forms.
After opening the first few envelopes. I suddenly came to an astonishing discovery. Not only did the form print out on the large mainframe IBM printers used in office areas, it also had printed out on other types of printers…. I opened one envelope and found the form printed out on a “Work Order” printer. The paper size was different than the standard paper size, and I hadn’t put a page feed at the end of the document, so, it had left the paper in the middle of the page…. “Uh Oh”.
My “Uh Oh” changed to “UH OH!” after opening a few more of the inter-company envelopes. I found that the form had printed out on Pay Check Printers! And Billing Printers! “UH OH!” quickly changed to “OH NO!” When I read comments like “Under no circumstances print anything on this Printer Again!!!!” I realized I had really messed things up. By changing the font size and the quality settings, the billing, payroll and work order printers all had to be manually reset and the jobs that printed out paychecks, customer bills and employee work orders had to be re-run!
After taking all the forms out of their envelopes, the stack of papers was over 4 inches thick, just to give you an idea about how many responses we had.
A couple of hours later, Tom Gibson called me to his office. “Uh Oh.” (remember… One “uh oh” erases all previous “atta boy”s). When I entered Tom’s office, I could tell that something was definitely wrong. Like I mentioned earlier. Tom’s ears were beet red…. and in case you don’t know what a beet looks like. Here is one:
The same color of Tom Gibson’s ears
Of course… I knew what this was all about, only I didn’t know yet, how Tom had found out about it…. Tom began by saying…. “Ron Kilman just received a call from James Harlow asking him who is Kevin Breazile and why is he printing something out on my printer? Ron didn’t like the fact that he wasn’t aware that you had sent something to the President of the Company’s printer.
James G. Harlow Jr.
Sorry. That’s the biggest picture I could find of James Harlow….
Um what could I say? So, I said this…
“Well. This was a quality idea that our team had. We wanted to collect the names of people that used each printer so that we could send in a proposal to have the printer ID added in the Corporate Directory.”
I didn’t mention that Harlow’s Secretary had returned the form with all the people that used his computer as I had requested, because I knew that the President of the Electric Company was not asking because he was upset that I had printed something out on his printer. No. He had probably been told that the reason the bills were late being sent to the one million customers that month was because some kook had messed up their printers and the jobs had to be run over again causing the delay. So, I thought it was best not to go down that route at this time…
So, I stuck with my story, which was the truth…. I had printed out the forms on all the printers as part of a quality idea by our CST. — I also didn’t mention that three years earlier, Tom had asked me to learn everything I could about the company computer, because he believe that the computer was going to be the wave of the future.
Even though Tom believed my explanation, he told me…. “Kevin, Ron never wants this to happen again, therefore, you are never to send anything out of this plant without Ron Kilman’s personal approval. Is that clear?”
I replied to Tom that this was unreasonable. I send things to other departments all the time. I send Substation Inspection forms, and blueprint revisions and all sorts of other forms downtown all the time. Ron Kilman wouldn’t want to waste his time approving all those things….
Tom thought about it and revised his statement…. “Then, don’t ever send out anything that isn’t part of your normal daily job without Ron’s approval first.” — Ok. I thought…. this works, since everything I do is part of my normal daily job…. Even printing out forms on all the printers in the company… since that was part of our normal “Quality Process” Customer Service Team activity…. So, I happily agreed. And I left Tom’s office happy that I hadn’t joined the ranks of the unemployed.
That was one thing about working at the plant at this time. As long as your heart was in the right place…. That is, you tried your best to keep the electricity humming through the electric lines…. then the chances of being fired for messing up, even as big of a mess up as this, most often didn’t end up by losing your job.
I sometimes think that this was my biggest mess up of all time… however…. after this episode was over… there was a part two to this story….. Believe it or not…. Someone else in the company was overjoyed about what I had just done. They had been trying to do something similar for a long time, only to be told that it was impossible. — Doing the Impossible… I was good at that… Part two of this story is a story for another day…
Since this is a repost of this story, I have written part two, which you can read here: “Printing Impossible Power Plant Fast News Post“.
Working Smarter with Power Plant Dumb Terminals
Originally posted January 3, 2014:
After the reorganization at the coal-fired power plant in North Central Oklahoma during 1987, a bunch of new faces showed up at the plant. I mentioned in last week’s post that we had a new plant manager, Ron Kilman (See Post: “From Pioneers to Power Plant Managers“). In that post I also mentioned that the PC age was rapidly growing and I had bought a computer of my own and was eager to learn more. The Electrical Supervisor, Leroy Godfrey had retired, and was replaced by a guy named Tom Gibson. Tom was a good supervisor who was willing to think out of the box.
Tom gave me one of my first assignments directly by calling me to his office. Well, Leroy had never really called me to his office before. When Leroy wanted to chew you out, he was happy to come down to the Electric Shop and do it, so I didn’t really know what to expect by being “called to his office”. Believe me… it wasn’t the last time he had “called me to his office.” But it was the most satisfying time. Mainly because this time, when I arrived, Tom’s face wasn’t beet red with anger like it was on one later occasion.
This is what Tom told me to do… He said that we needed to install computer terminals all over the plant. They had a chart where they wanted the terminals to go. There were about 15 locations all over the plant including the coalyard which was about 1/2 mile from the main plant. Along with those, there were a bunch of IBM Network printers that needed to be installed with the terminals.
Then Tom told me the best part. He wanted me to do it all myself. Then he told me an even better part…. He said, (and I quote) “I want you to learn everything you can about this computer stuff. I think it will come in handy.” As my friend Stephen Todd at Dell would say, “That was the ‘Keys to the Kingdom”. I told him I would be glad to do everything he asked.
That last part later came back to haunt Tom…. but he did tell me…. learn “everything” I could about the computer. When he was referring to “The Computer”, he was talking about the company mainframe, a Honeywell system that resided in Oklahoma City at Corporate Headquarters.
A Honeywell Mainframe computer
The Terminals I was going to install were called “Dumb terminals”. they weren’t computers, they were just monitors with a keyboard that connected directly to a switch back in the telephone room that was connected via a microwave link directly to Oklahoma City and the Honeywell system:
A DEC terminal like this.
So, when I returned to the electric shop, I began my “hacker” apprenticeship. One that would later allow me to harass Gene Day in the Control Room, confuse Dick Dale in the warehouse, cause headaches for the IT department downtown, and finally cause the President of the Electric Company to personally call our Plant Manager Ron asking who was this guy Kevin Breazile! Hence the reason for Tom Gibson’s beet red face a few years later. But that is another story for another time.
I had two things right away that I had to figure out. How was I going to run cables from the telephone room in the office to each of the places around the plant that needed a computer terminal and what are these funny connectors and what do I need to do with them?
A Modular DB25M to RJ45 Adapter
Ok, so I figured they plugged in the back of the terminal and then there was a Cat1 cable (no, not a Cat3, a Cat1) that plugged into that, and needed to plug into a jack in the wall that I was going to have to install. They called these funny connectors “Hoods”. The 25 pin Hoods that we used were blue. We had 9 pin hoods also that we used for the actual PCs that the clerks and the chemist were using. They had an emulator program to make them act like a dumb terminal:
A Serial RS232-DB9 9-Pin Female to RJ45 Adapter
In an early post called “Power Plant Men’s Club Prizes and a Story of Luck” I explained how I have always been cursed with being very lucky. Well, that’s what some may call it, but I prefer to believe that one of my best friends St. Anthony helps me out at certain times. Well, this was one time when I asked for his assistance. St. Anthony of Padua is considered the Patron Saint of lost items. So, I asked him to help me figure out how I was going to do all this work in a reasonable amount of time.
St. Anthony of Padua
As is often the case, St. Anthony pointed me in the right direction. This particular day, he told me to tell my problem to Charles Foster. My close friend and one of the two Electric Shop foremen (not mine. I was working for Andy Tubbs). So, during lunch I told him what Tom Gibson told me to do, and showed him the blueprints where they wanted the terminals placed throughout the plant.
One of the places that needed a terminal was right there in the electric shop office. Charles looked around the office and said, “You know what? there used to be an old intercom system in this office that I think goes up to the telephone room. In fact, I think all the intercoms that were originally installed in the plant went to the telephone room.”
An old intercom sort of like this only older and in a box that sat on the desk and it had more switches
I vaguely remembered the intercoms when I was working as a summer help as there used to be an old box sitting in the garage when I worked for Stanley Elmore. They were later cut out and removed, because it wasn’t really practical and so it wasn’t used. Charles told me to start there, because there were intercoms everywhere. In the control room, the warehouse, and even in the coalyard! And definitely in the office area. This was just what I needed to hear. My work was already half done.
I pulled the cables out from under the desk where they had been cut and checked them out. There were definitely enough cable pairs to do the job. In most places I had to install both a terminal and a printer, so I had a lot of dual wall jacks just for this job:
A dual RJ45 Wall Jack
There were some places where the intercom system didn’t go where I needed to install either a dumb terminal or at least connect a computer. So, I was looking for any kind of alternate way to install the jack without having to run cables all the way from the telephone room to these locations. So, I went out and bought a book about networking so that I could learn more about what was really going on. If I had bought it a few years later it might have been called “Dumb Terminals for Dummies”, but the Dummies books hadn’t come around yet.
I have since thrown that book away after using it for years to prop up the corner of our sofa bed for the times when my mom would come and visit and she would sleep on the bed, only it had a broken bracket, and the Networking book was just the right thickness to level the bed…. But there was one page in the book that I found that allowed me to hook up dumb terminals in places where there was only a phone line.
You see. When the phone lines were run throughout the plant, they used a three pair cable. Well. A phone really only uses two wires (or one pair). so, this left 4 more wires not doing anything. The only problem was that the dumb terminal used 4 pair, or 8 wires…
An RJ45 Cable has 8 wires
So, when I was reading the networking book, I ran across a diagram that made me stop and stare. I like to think that I was holding a half eaten apple in my hand and I had just taken a bite when I stopped mid-bite and stared. It would have been a nice picture to remember sort of like when the apple fell on Newton’s head. Only we didn’t have cellphones with cameras in those days, so no one was around to take my picture. The diagram I saw was this:
The pin configuration for an RJ45 connector
What? This showed 4 of the wires are nothing but grounds…. The network cable only really uses 4 of the 8 wires. Which means I only needed two pair. And guess what? The phone lines run all over the plant were 3 pair with only one pair being used! So, I was able to install the computer jacks right next to the telephone jacks and use the same cable that the telephone was using, and they all tied back to the telephone room where the main computer switch was located that connected to the Mainframe computer back in Oklahoma City through something called a Memotec X.25 Modem.
So, now that I have gone through all this detail to tell you how I was able to quickly install all these terminals and printers around the plant in a way as if it is exciting (because it is to me). I know that many of you are so bored out of your gourd that you have already stopped reading before you have reached this sentence…. I suppose those of you that are still following along are wondering “Why?”
Why would we want to install all these dumb terminals throughout a power plant that connected to the Honeywell Mainframe down at Corporate Headquarters? Well. It was because all the plant operators, mechanics, welders, machinists, electricians, instrument and controls and heavy equipment operators were going to start using it to do stuff. Yeah. All of us were being introduced to the computer age. From the janitor on up.
Each printer had 4 character ID that identified it, so if you were looking at a work order on the terminal, you could choose to print it. You just had to know the 4 character number and you could print the work order out on any computer in the company. Usually, this meant, you wanted to use the printer that was closest to you. But if you wanted to print something out for the warehouse, as long as you knew their printer ID, you could send them a printout of some part that you wanted them to retrieve for you. Then call them up and tell them you printed something out on their printer.
Ok. So the average Joe didn’t see much benefit, but it did get them used to seeing computer monitors all over the place, which at least helped them in the future when the real computers showed up. Right now, they were just “Dumb Terminals” and that’s what a lot of the operators and maintenance people thought… they are just dumb…
I, on the other hand was in hog heaven. You see. I had called downtown to the IT department and asked to get a user name so that I could log directly into the mainframe. After all, my supervisor Tom had told me to learn “everything” I could about “this computer”. So, I took him up on it. I quickly was learning UNIX commands, though at the time, I didn’t know that’s what they were called.
I began learning the Computer language called “A” before I realized there was a “B” language and a “C” language, and that C was the one that was really used at the time. As it turned out the mainframe had manuals for everything right on it. That is how I was able to cause so much trouble the next few years.
Oh, and one more interesting thing I discovered on the mainframe. It had this interesting feature called “Email”. Yeah. Only, after figuring out how to pull up a list of all the emails on the system I found that there was only a handful of people that actually had e-mail addresses. So, the only person I would email on the mainframe was an engineer named Craig Henry.
Craig Henry. Engineer and Gentleman
I had met him briefly once, but in the next few years, he was a valuable source of information. Email seemed like a great idea, but what good was it if there was only a few people you could send an email?
As for Craig Henry… As Humphrey Bogart said to Claude Rains in Casablanca, “This is the beginning of a Beautiful Friendship.” Come to think of it… Craig Henry sort of reminds me of Claude Rains… I must admit, I learned a lot more from him than he ever learned from me.

Already I had learned about the escape codes used by the large IBM printers that were used throughout the company at the time. This allowed me to create graphic images on the printer as well as large bold letters.
IBM Dot Matrix Network Printer
Besides the telephone and inter-company mail, printers were the only other way to communicate to non-present Power Plant Men in 1989. We had not yet been introduced to e-mail. I was one of the few people in the company that had an e-mail address on the mainframe, and the only other person that I knew that I could write to was Craig Henry, a Corporate Engineer downtown.
Craig Henry. Engineer and Gentleman
Much like the first time when I met Gene Day, when I first encountered Craig Henry, I could tell right away that he was a down-to-earth person that would shoot straight. Craig probably wouldn’t remember this far into the future that I would reach out to him occasionally just to say “Hi” and to pick his brain about how the corporate IT infrastructure was setup. I figured since he was one of the few people in the company that even knew what an e-mail address was at the time, he most likely had more knowledge about such things than the average person in Corporate Headquarters.
After finding out that Gene Day would go work out at the Rock Gym in Stillwater, Oklahoma after work, and I had played the joke on him with the notes from the private investigator, I used my knowledge of Printer Escape codes to write documents on the mainframe that when printed out would turn on the graphic commands on the printer so that I could print out pictures. I don’t mean that I would have a saved picture that I would send to a printer like we might do today. No. I had to create these pictures one pixel at a time using commands in a UNIX document on the mainframe. It was all codes that would not make sense to anyone that didn’t know the graphic commands of the IBM printers.
I had been teasing Gene Day about meeting up with a young “coed” from the University at the Gym each day. I would do this by printing out messages on the Control Room printer by the the Shift Supervisor’s office when I knew that Gene Day was there filling in as the Shift Supervisor. They were usually notes from someone that called herself “Bunny”. Usually they were short notes or “love letters” from Bunny just saying something about how she enjoyed her time with Gene at the Gym.
At the bottom I would sign it “Bunny” then under it, the printer would read the graphic commands and create a small Playboy Bunny symbol under the name. At the end, the document would send a command that would put the printer back into the text mode.
Of course. Whenever I walked into the control room shortly after, just to see how the precipitator was doing, Gene Day would confront me about the notes. With a grin on his face he would say, “This isn’t funny! What if my wife found one of these notes?” — Like that was ever going to happen…. unless he was like me, and likes to save everything.
Note to Gene Day from Bunny (now she knows)
In order to create the bunny at the bottom I had to create the pixels in small blocks of 9 pixel patterns. Here is the code I used to create the bunny:
See? I save everything
In the last couple of weeks I have written about how the Power Plant Men were introduced to the “Quality Process” (otherwise known as “Six Sigma”). We had created teams with our crews and we met once each week to come up with Quality ideas. By August, 1993, I had received my official Certificate Certifying that I had completed all the QuickStart training and was on my way to making a difference in the Power Plant World!
My Customer Service Team Certificate. This made me official!
So, what do these two events have in common and how did this lead the President of the Electric Company to send out a search warrant on a lowly (lowlife is more like it) Plant Electrician in North Central Oklahoma? Well. This is what happened…
First you have to remember that in 1993, the Internet was not easily accessible by the general public. Company e-mail was still not a reality in our company. We had dumb terminals and large IBM printers. That was the extent of most employees interaction with a computer. Each printer had a designation. It was a four character ID beginning with a “P”. So, the printer in the Electric Shop Office might be…. P123. I needed to know this number if I wanted to send something to it.
At the time, the only thing people had to send to each other were requests for things from the mainframe systems that were used to run the company. So, for instance, if you wanted to request some parts from the warehouse at our plant, we would send over a list of parts to the warehouse printer where Dick Dale and Darlene Mitchell would pick it up and go retrieve the parts. So, the people that used the terminals and computers with mainframe emulators on them knew the most commonly used printer numbers in the plant.
If you wanted to send something to someone in Oklahoma City, or to the Power Plant in Muskogee, then you would have to call over there and ask the person what their Printer ID is so you can be sure you are sending your request to the appropriate printer. Without e-mail, and any other form of computerized communication. This was the only way at the time.
So, after our Customer Service Team was formed, we would meet once each week to brainstorm new ideas that would benefit the company. Andy Tubbs was our team leader, as he was our foreman.
Andy Tubbs – True Power Plant Electrician
The other members of our Customer Service Team were Diana Brien, Scott Hubbard, Sonny Kendrick, Ben Davis and Gary Wehunt. I haven’t properly introduced my bucket buddy Diana Brien in a post before. I have recently obtained a photograph that I can share:
My Bucket Buddy Diana Brien
We were called bucket buddies because we carried tool buckets with us whenever we went to work on something. They doubled as our stool and tripled as our trash can.
Thursday, July 15, 1993 during our Quality Brainstorming session, while we were pouring out ideas like…. “What if we changed out the street lights at the plant so that they would be different colors…. wouldn’t that help morale?…. and “How about if we wrapped fluorescent Christmas lights around the high voltage electric lines between here and Oklahoma City so that they could light up the night with colorful lights during the Christmas Season?”….. And other ingenious Brainstorming ideas that are bound to pull up an occasional brilliant idea….. well. One such idea popped up!
I don’t remember which one of our brilliant brainstorming ideas conjured up this idea, but Andy Tubbs suddenly blurted out…. “What if we had the Printer IDs added as a column in the Corporate Directory? — You see, each quarter we received an updated copy of the Corporate Phone Book. It included the names and office phone numbers of all the Electric Company employees. It also included their mail code. So, if you wanted to send something through inter-company mail to them, you would know where to send it. Our mail code was PP75. That was the code for our power plant.
So, what if we added a column where we had the printer ID that each person would use for people to send printed requests, among other things? This was Brilliant! We could just make this proposal and send it downtown to Corporate Headquarters where it would be lost in the “mail”. Or we could do more research to prove that it was a possible proposal that was really do-able.
So, I suggested…. Well… I can print a form out on every printer in the entire company requesting that they include all the names of all the people that use that printer and mail it through inter-company mail back to me at PP75. — I had recently uncovered a special printer command that allowed me to do this hidden away on the Honeywell mainframe. So, we took a vote and it was decided that we would pursue this proposal. I set to work on creating the form that I would send to every printer. If we could not only send the proposal to the Communications department downtown, but also a list of everyone and their printers, the work would already have been done for them.
I wanted to send a real fancy letter because I had already created a header using the Quality print settings on the printers. I had created a Company Logo that (I thought) ingeniously used the backspace command to create two words with one word on top of the other in the middle of a sentence…. Our company began as Oklahoma Gas and….. in the logo, I wanted the word Gas to be on top of the word And as it was in our company logo in smaller letters than the others. So… after playing around with it for a while, I created the logo and had it saved on the mainframe.
I know. I was rotten to Gene Day. Here is an example of the header with the “GAS AND” in the middle of the name. Remember. This is on an old IBM Dot Matrix printer using the High Quality setting
After attaching the header to the form, I included a message that told the person that discovered the form on the printer to add the names of all people who used the printer below and to send the form to Kevin Breazile at PP75. As I mentioned. In order to make the form look pretty, I turned on the Quality Print settings on the printer at the beginning of the document. Like the story of the Sorcerer’s Apprentice….. I didn’t know a good way to turn off all the settings I changed to revert the printers back to their original settings.
I ran the command to send the document to every printer on the print server and away they went…. A copy printed out on the printer in the Electric Shop office so I knew it was working. Copies printed out on the other 12 printers at our plant. They also printed out on the 500 other printers throughout Oklahoma. — With the thought that “My work here is done.” I went back to work repairing plant electric equipment.
The following Monday I had the day off. When I returned to work on Tuesday, Denise Anson called me from the front office. She said that I had a large stack of mail. I thought, “Oh good!” Results from our request on Thursday have arrived! I hurried up to the front office.
When I entered the mail cubicle I was surprised to see how big the pile of envelopes were. The stack of inter-company envelopes was over two feet high. “Um…. Thanks….” I said to Denise. I picked up the stack and headed back to the Electric Shop to sort out the forms.
After opening the first few envelopes. I suddenly came to an astonishing discovery. Not only did the form print out on the large mainframe IBM printers used in office areas, it also had printed out on other types of printers…. I opened one envelope and found the form printed out on a “Work Order” printer. The paper size was different than the standard paper size, and I hadn’t put a page feed at the end of the document, so, it had left the paper in the middle of the page…. “Uh Oh”.
My “Uh Oh” changed to “UH OH!” after opening a few more of the inter-company envelopes. I found that the form had printed out on Pay Check Printers! And Billing Printers! “UH OH!” quickly changed to “OH NO!” When I read comments like “Under no circumstances print anything on this Printer Again!!!!” I realized I had really messed things up. By changing the font size and the quality settings, the billing, payroll and work order printers all had to be manually reset and the jobs that printed out paychecks, customer bills and employee work orders had to be re-run!
After taking all the forms out of their envelopes, the stack of papers was over 4 inches thick, just to give you an idea about how many responses we had.
A couple of hours later, Tom Gibson called me to his office. “Uh Oh.” (remember… One “uh oh” erases all previous “atta boy”s). When I entered Tom’s office, I could tell that something was definitely wrong. Like I mentioned earlier. Tom’s ears were beet red…. and in case you don’t know what a beet looks like. Here is one:
The same color of Tom Gibson’s ears
Of course… I knew what this was all about, only I didn’t know yet, how Tom had found out about it…. Tom began by saying…. “Ron Kilman just received a call from James Harlow asking him who is Kevin Breazile and why is he printing something out on my printer? Ron didn’t like the fact that he wasn’t aware that you had sent something to the President of the Company’s printer.
James G. Harlow Jr.
Sorry. That’s the biggest picture I could find of James Harlow….
Um what could I say? So, I said this…
“Well. This was a quality idea that our team had. We wanted to collect the names of people that used each printer so that we could send in a proposal to have the printer ID added in the Corporate Directory.”
I didn’t mention that Harlow’s Secretary had returned the form with all the people that used his computer as I had requested, because I knew that the President of the Electric Company was not asking because he was upset that I had printed something out on his printer. No. He had probably been told that the reason the bills were late being sent to the one million customers that month was because some kook had messed up their printers and the jobs had to be run over again causing the delay. So, I thought it was best not to go down that route at this time…
So, I stuck with my story, which was the truth…. I had printed out the forms on all the printers as part of a quality idea by our CST. — I also didn’t mention that three years earlier, Tom had asked me to learn everything I could about the company computer, because he believe that the computer was going to be the wave of the future.
Even though Tom believed my explanation, he told me…. “Kevin, Ron never wants this to happen again, therefore, you are never to send anything out of this plant without Ron Kilman’s personal approval. Is that clear?”
I replied to Tom that this was unreasonable. I send things to other departments all the time. I send Substation Inspection forms, and blueprint revisions and all sorts of other forms downtown all the time. Ron Kilman wouldn’t want to waste his time approving all those things….
Tom thought about it and revised his statement…. “Then, don’t ever send out anything that isn’t part of your normal daily job without Ron’s approval first.” — Ok. I thought…. this works, since everything I do is part of my normal daily job…. Even printing out forms on all the printers in the company… since that was part of our normal “Quality Process” Customer Service Team activity…. So, I happily agreed. And I left Tom’s office happy that I hadn’t joined the ranks of the unemployed.
That was one thing about working at the plant at this time. As long as your heart was in the right place…. That is, you tried your best to keep the electricity humming through the electric lines…. then the chances of being fired for messing up, even as big of a mess up as this, most often didn’t end up by losing your job.
I sometimes think that this was my biggest mess up of all time… however…. after this episode was over… there was a part two to this story….. Believe it or not…. Someone else in the company was overjoyed about what I had just done. They had been trying to do something similar for a long time, only to be told that it was impossible. — Doing the Impossible… I was good at that… Part two of this story is a story for another day…
Since this is a repost of this story, I have written part two, which you can read here: “Printing Impossible Power Plant Fast News Post“.
Power Plant Customer Service Team Gone Wild

I never would have guessed that playing Power Plant Man jokes on Gene Day would have led me to the “Uh Oh!” moment I later encountered when I was told in no uncertain terms that the President of the Electric Company, James G. Harlow Junior was personally upset with something I had done. I had learned my first year as a summer help at the coal-fired Power Plant in North Central Oklahoma that “One ‘Uh Oh’ wipes out all previous ‘Atta Boys’!” I could tell by the way the Electric Supervisor, Tom Gibson’s ears were glowing red that this was considered a little more serious than I had first realized.
I have mentioned in previous posts that playing jokes on Gene Day was one of my favorite Power Plant Man Pastimes. See the post, “Power Plant Humor and Joking With Gene Day“. Also see, “Psychological Profile of a Power Plant Control Room Operator“.

Working Smarter with Power Plant Dumb Terminals
Originally posted January 3, 2014:
After the reorganization at the coal-fired power plant in North Central Oklahoma during 1987, a bunch of new faces showed up at the plant. I mentioned in last week’s post that we had a new plant manager, Ron Kilman (See Post: “From Pioneers to Power Plant Managers“). In that post I also mentioned that the PC age was rapidly growing and I had bought a computer of my own and was eager to learn more. The Electrical Supervisor, Leroy Godfrey had retired, and was replaced by a guy named Tom Gibson. Tom was a good supervisor who was willing to think out of the box.
Tom gave me one of my first assignments directly by calling me to his office. Well, Leroy had never really called me to his office before. When Leroy wanted to chew you out, he was happy to come down to the Electric Shop and do it, so I didn’t really know what to expect by being “called to his office”. Believe me… it wasn’t the last time he had “called me to his office.” But it was the most satisfying time. Mainly because this time, when I arrived, Tom’s face wasn’t beet red with anger like it was on one later occasion.
This is what Tom told me to do… He said that we needed to install computer terminals all over the plant. They had a chart where they wanted the terminals to go. There were about 15 locations all over the plant including the coalyard which was about 1/2 mile from the main plant. Along with those, there were a bunch of IBM Network printers that needed to be installed with the terminals.
Then Tom told me the best part. He wanted me to do it all myself. Then he told me an even better part…. He said, (and I quote) “I want you to learn everything you can about this computer stuff. I think it will come in handy.” As my friend Stephen Todd at Dell would say, “That was the ‘Keys to the Kingdom”. I told him I would be glad to do everything he asked.
That last part later came back to haunt Tom…. but he did tell me…. learn “everything” I could about the computer. When he was referring to “The Computer”, he was talking about the company mainframe, a Honeywell system that resided in Oklahoma City at Corporate Headquarters.
A Honeywell Mainframe computer
The Terminals I was going to install were called “Dumb terminals”. they weren’t computers, they were just monitors with a keyboard that connected directly to a switch back in the telephone room that was connected via a microwave link directly to Oklahoma City and the Honeywell system:
A DEC terminal like this.
So, when I returned to the electric shop, I began my “hacker” apprenticeship. One that would later allow me to harass Gene Day in the Control Room, confuse Dick Dale in the warehouse, cause headaches for the IT department downtown, and finally cause the President of the Electric Company to personally call our Plant Manager Ron asking who was this guy Kevin Breazile! Hence the reason for Tom Gibson’s beet red face a few years later. But that is another story for another time.
I had two things right away that I had to figure out. How was I going to run cables from the telephone room in the office to each of the places around the plant that needed a computer terminal and what are these funny connectors and what do I need to do with them?
A Modular DB25M to RJ45 Adapter
Ok, so I figured they plugged in the back of the terminal and then there was a Cat1 cable (no, not a Cat3, a Cat1) that plugged into that, and needed to plug into a jack in the wall that I was going to have to install. They called these funny connectors “Hoods”. The 25 pin Hoods that we used were blue. We had 9 pin hoods also that we used for the actual PCs that the clerks and the chemist were using. They had an emulator program to make them act like a dumb terminal:
A Serial RS232-DB9 9-Pin Female to RJ45 Adapter
In an early post called “Power Plant Men’s Club Prizes and a Story of Luck” I explained how I have always been cursed with being very lucky. Well, that’s what some may call it, but I prefer to believe that one of my best friends St. Anthony helps me out at certain times. Well, this was one time when I asked for his assistance. St. Anthony of Padua is considered the Patron Saint of lost items. So, I asked him to help me figure out how I was going to do all this work in a reasonable amount of time.
St. Anthony of Padua
As is often the case, St. Anthony pointed me in the right direction. This particular day, he told me to tell my problem to Charles Foster. My close friend and one of the two Electric Shop foremen (not mine. I was working for Andy Tubbs). So, during lunch I told him what Tom Gibson told me to do, and showed him the blueprints where they wanted the terminals placed throughout the plant.
One of the places that needed a terminal was right there in the electric shop office. Charles looked around the office and said, “You know what? there used to be an old intercom system in this office that I think goes up to the telephone room. In fact, I think all the intercoms that were originally installed in the plant went to the telephone room.”
An old intercom sort of like this only older and in a box that sat on the desk and it had more switches
I vaguely remembered the intercoms when I was working as a summer help as there used to be an old box sitting in the garage when I worked for Stanley Elmore. They were later cut out and removed, because it wasn’t really practical and so it wasn’t used. Charles told me to start there, because there were intercoms everywhere. In the control room, the warehouse, and even in the coalyard! And definitely in the office area. This was just what I needed to hear. My work was already half done.
I pulled the cables out from under the desk where they had been cut and checked them out. There were definitely enough cable pairs to do the job. In most places I had to install both a terminal and a printer, so I had a lot of dual wall jacks just for this job:
A dual RJ45 Wall Jack
There were some places where the intercom system didn’t go where I needed to install either a dumb terminal or at least connect a computer. So, I was looking for any kind of alternate way to install the jack without having to run cables all the way from the telephone room to these locations. So, I went out and bought a book about networking so that I could learn more about what was really going on. If I had bought it a few years later it might have been called “Dumb Terminals for Dummies”, but the Dummies books hadn’t come around yet.
I have since thrown that book away after using it for years to prop up the corner of our sofa bed for the times when my mom would come and visit and she would sleep on the bed, only it had a broken bracket, and the Networking book was just the right thickness to level the bed…. But there was one page in the book that I found that allowed me to hook up dumb terminals in places where there was only a phone line.
You see. When the phone lines were run throughout the plant, they used a three pair cable. Well. A phone really only uses two wires (or one pair). so, this left 4 more wires not doing anything. The only problem was that the dumb terminal used 4 pair, or 8 wires…
An RJ45 Cable has 8 wires
So, when I was reading the networking book, I ran across a diagram that made me stop and stare. I like to think that I was holding a half eaten apple in my hand and I had just taken a bite when I stopped mid-bite and stared. It would have been a nice picture to remember sort of like when the apple fell on Newton’s head. Only we didn’t have cellphones with cameras in those days, so no one was around to take my picture. The diagram I saw was this:
The pin configuration for an RJ45 connector
What? This showed 4 of the wires are nothing but grounds…. The network cable only really uses 4 of the 8 wires. Which means I only needed two pair. And guess what? The phone lines run all over the plant were 3 pair with only one pair being used! So, I was able to install the computer jacks right next to the telephone jacks and use the same cable that the telephone was using, and they all tied back to the telephone room where the main computer switch was located that connected to the Mainframe computer back in Oklahoma City through something called a Memotec X.25 Modem.
So, now that I have gone through all this detail to tell you how I was able to quickly install all these terminals and printers around the plant in a way as if it is exciting (because it is to me). I know that many of you are so bored out of your gourd that you have already stopped reading before you have reached this sentence…. I suppose those of you that are still following along are wondering “Why?”
Why would we want to install all these dumb terminals throughout a power plant that connected to the Honeywell Mainframe down at Corporate Headquarters? Well. It was because all the plant operators, mechanics, welders, machinists, electricians, instrument and controls and heavy equipment operators were going to start using it to do stuff. Yeah. All of us were being introduced to the computer age. From the janitor on up.
Each printer had 4 character ID that identified it, so if you were looking at a work order on the terminal, you could choose to print it. You just had to know the 4 character number and you could print the work order out on any computer in the company. Usually, this meant, you wanted to use the printer that was closest to you. But if you wanted to print something out for the warehouse, as long as you knew their printer ID, you could send them a printout of some part that you wanted them to retrieve for you. Then call them up and tell them you printed something out on their printer.
Ok. So the average Joe didn’t see much benefit, but it did get them used to seeing computer monitors all over the place, which at least helped them in the future when the real computers showed up. Right now, they were just “Dumb Terminals” and that’s what a lot of the operators and maintenance people thought… they are just dumb…
I, on the other hand was in hog heaven. You see. I had called downtown to the IT department and asked to get a user name so that I could log directly into the mainframe. After all, my supervisor Tom had told me to learn “everything” I could about “this computer”. So, I took him up on it. I quickly was learning UNIX commands, though at the time, I didn’t know that’s what they were called.
I began learning the Computer language called “A” before I realized there was a “B” language and a “C” language, and that C was the one that was really used at the time. As it turned out the mainframe had manuals for everything right on it. That is how I was able to cause so much trouble the next few years.
Oh, and one more interesting thing I discovered on the mainframe. It had this interesting feature called “Email”. Yeah. Only, after figuring out how to pull up a list of all the emails on the system I found that there was only a handful of people that actually had e-mail addresses. So, the only person I would email on the mainframe was an engineer named Craig Henry.
Craig Henry. Engineer and Gentleman
I had met him briefly once, but in the next few years, he was a valuable source of information. Email seemed like a great idea, but what good was it if there was only a few people you could send an email?
As for Craig Henry… As Humphrey Bogart said to Claude Rains in Casablanca, “This is the beginning of a Beautiful Friendship.” Come to think of it… Craig Henry sort of reminds me of Claude Rains… I must admit, I learned a lot more from him than he ever learned from me.
Power Plant Customer Service Team Gone Wild
I never would have guessed that playing Power Plant Man jokes on Gene Day would have led me to the “Uh Oh!” moment I later encountered when I was told in no uncertain terms that the President of the Electric Company, James G. Harlow Junior was personally upset with something I had done. I had learned my first year as a summer help at the coal-fired Power Plant in North Central Oklahoma that “One ‘Uh Oh’ wipes out all previous ‘Atta Boys’!” I could tell by the way the Electric Supervisor, Tom Gibson’s ears were glowing red that this was considered a little more serious than I had first realized.
I have mentioned in previous posts that playing jokes on Gene Day was one of my favorite Power Plant Man Pastimes. See the post, “Power Plant Humor and Joking With Gene Day“. Also see, “Psychological Profile of a Power Plant Control Room Operator“. My lunch breaks were usually consumed with learning more about how to program the Honeywell mainframe computer used by just about all the company processes that actually ran the company from payroll, to billing, to work orders and Inventory. I figured that as I learned more about the computer system, the more elaborate jokes I would be able to play on Gene.
Already I had learned about the escape codes used by the large IBM printers that were used throughout the company at the time.
IBM Dot Matrix Network Printer
Besides the telephone and inter-company mail, printers were the only other way to communicate to non-present Power Plant Men in 1989. We had not yet been introduced to e-mail. I was one of the few people in the company that had an e-mail address, and the only other person that I knew that I could write to was Craig Henry, a Corporate Engineer downtown.
Craig Henry. Engineer and Gentleman
Much like the first time when I met Gene Day, when I first encountered Craig Henry, I could tell right away that he was a down-to-earth person that would shoot straight. Craig probably wouldn’t remember this far into the future that I would reach out to him occasionally just to say “Hi” and to pick his brain about how the corporate IT infrastructure was setup. I figured since he was one of the few people in the company that even knew what an e-mail address was at the time, he most likely had more knowledge about such things than the average person in Corporate Headquarters.
After finding out that Gene Day would go work out at the Rock Gym in Stillwater, Oklahoma after work, and I had played the joke on him with the notes from the private investigator, I used my knowledge of Printer Escape codes to write documents on the mainframe that when printed out would turn on the graphic commands on the printer so that I could print out pictures. I don’t mean that I would have a saved picture that I would send to a printer like we might do today. No. I had to create these pictures one pixel at a time using commands in a UNIX document on the mainframe. It was all codes that would not make sense to anyone that didn’t know the graphic commands of the IBM printers.
I had been teasing Gene Day about meeting up with a young “coed” from the University at the Gym each day. I would do this by printing out messages on the Control Room printer by the the Shift Supervisor’s office when I knew that Gene Day was there filling in as the Shift Supervisor. They were usually notes from someone that called herself “Bunny”. Usually they were short notes or “love letters” from Bunny just saying something about how she enjoyed her time with Gene at the Gym.
At the bottom I would sign it “Bunny” then under it, the printer would read the graphic commands and create a small Playboy Bunny symbol under the name. At the end, the document would send a command that would put the printer back into the text mode.
Of course. Whenever I walked into the control room shortly after, just to see how the precipitator was doing, Gene Day would confront me about the notes. With a grin on his face he would say, “This isn’t funny! What if my wife found one of these notes?” — Like that was ever going to happen…. unless he was like me, and like to save everything.
In the last couple of weeks I have written about how the Power Plant Men were introduced to the “Quality Process” (otherwise known as “Six Sigma”). We had created teams with our crews and we met once each week to come up with Quality ideas. In August, 1993, I had received my official Certificate Certifying that I had completed all the QuickStart training and was on my way to making a difference in the Power Plant World!
My Customer Service Team Certificate. This made me official!
So, what do these two events have in common and how did this lead the President of the Electric Company to send out a search warrant on a lowly Plant Electrician in North Central Oklahoma? Well. This is what happened…
First you have to remember that in 1993, the Internet was not easily accessible by the general public. Company e-mail was still not a reality in our company. We had dumb terminals and large IBM printers. That was the extent of most employees interaction with a computer. Each printer had a designation. It was a four character ID beginning with a “P”. So, the printer in the Electric Shop Office might be…. P123. I needed to know this number if I wanted to send something to it.
At the time, the only thing people had to send to each other were requests for things from the mainframe systems that were used to run the company. So, for instance, if you wanted to request some parts from the warehouse at our plant, we would send over a list of parts to the warehouse printer where Dick Dale and Darlene Mitchell would pick it up and go retrieve the parts. So, the people that used the terminals and computers with mainframe emulators on them knew the most commonly used printer numbers in the plant.
If you wanted to send something to someone in Oklahoma City, or to the Power Plant in Muskogee, then you would have to call over there and ask the person what their Printer ID is so you can be sure you are sending your request to the appropriate computer. Without e-mail, and any other form of computerized communication. This was the only way at the time.
So, after our Customer Service Team was formed, we would meet once each week to brainstorm new ideas that would benefit the company. Andy Tubbs was our team leader, as he was our foreman.
Andy Tubbs – True Power Plant Electrician
The other members of our Customer Service Team were Diana Brien, Scott Hubbard, Sonny Kendrick, Ben Davis and Gary Wehunt. I haven’t properly introduced my bucket buddy Diana Brien in a post before. I have recently obtained a photograph that I can share:
My Bucket Buddy Diana Brien
We were called bucket buddies because we carried tool buckets with us whenever we went to work on something. They doubled as our stool and tripled as our trash can.
Thursday, October 14, 1993 during our Quality Brainstorming session, while we were pouring out ideas like…. “What if we changed out the street lights at the plant so that they would be different colors…. wouldn’t that help morale?…. and “How about if we wrapped fluorescent Christmas lights around the high voltage electric lines between here and Oklahoma City so that they could light up the night with colorful lights during the Christmas Season?”….. And other ingenious Brainstorming ideas that are bound to pull up an occasional brilliant idea….. well. One such idea popped up!
I don’t remember which one of our brilliant brainstorming ideas conjured up this idea, but Andy Tubbs suddenly blurted out…. “What if we had the Printer IDs added as a column in the Corporate Directory? — You see, each quarter we received an updated copy of the Corporate Phone Book. It included the names and phone numbers of all the Electric Company employees. It also included their mail code. So, if you wanted to send something through inter-company mail to them, you would know where to send it. Our mail code was PP75. That was the code for our power plant.
So, what if we added a column where we had the printer ID that each person would use for people to send printed requests, among other things? This was Brilliant! We could just make this proposal and send it downtown to Corporate Headquarters where it would be lost in the “mail”. Or we could do more research to prove that it was a possible proposal that was really doable.
So, I suggested…. Well… I can print a form out on every printer in the entire company requesting that they include all the names of all the people on that use that printer and mail it through inter-company mail back to me at PP75. — I had recently uncovered a special printer command that allowed me to do this hidden away on the Honeywell mainframe. So, we took a vote and it was decided that we would pursue this proposal. I set to work on creating the form that I would send to every printer. If we could not only send the proposal to the Communications department downtown, but also a list of everyone and their printers, the work would already have been done for them.
I wanted to send a real fancy letter because I had already created a header using the Quality print settings on the printers. I had created a Company Logo that (I thought) ingeniously used the backspace command to create two words with one word on top of the other in the middle of a sentence…. Our company began as Oklahoma Gas and….. in the logo, I wanted the word Gas to be on top of the word And as it was in our company logo in smaller letters than the others. So… after playing around with it for a while, I created the logo and had it saved on the mainframe.
After attaching the header to the form, I included a message that told the person that discovered the form on the printer to add the names of all people who used the printer below and to send the form to Kevin Breazile at PP75. As I mentioned. In order to make the form look pretty, I turned on the Quality Print settings on the printer at the beginning of the document. Like the story of the Sorcerer’s Apprentice….. I didn’t know a good way to turn off all the settings I changed to revert the printers back to their original settings.
I ran the command to send the document to every printer on the print server and away they went…. A copy printed out on the printer in the Electric Shop office so I knew it was working. Copies printed out on the other 12 printers at our plant. They also printed out on the 500 other printers throughout Oklahoma. — With the thought that “My work here is done.” I went back to work repairing plant electric equipment.
The following Monday was my birthday, so in normal Power Plant Fashion, I had the day off. When I returned to work on Tuesday, Denise Anson called me from the front office. She said that I had a large stack of mail. I thought, “Oh good!” Results from our request on Thursday have arrived! I hurried up to the front office.
When I entered the mail cubicle I was surprised to see how big the pile of envelopes were. The stack of inter-company envelopes was over two feet high. “Um…. Thanks….” I said to Denise. I picked up the stack and headed back to the Electric Shop to sort out the forms.
After opening the first few envelopes. I suddenly came to an astonishing discovery. Not only did the form print out on the large mainframe IBM printers used in office areas, it also had printed out on other types of printers…. I opened one envelope and found the form printed out on a “Work Order” printer. The paper size was different than the standard paper size, and I hadn’t put a page feed at the end of the document, so, it had left the paper in the middle of the page…. “Uh Oh”.
My “Uh Oh” changed to “UH OH!” after opening a few more of the inter-company envelopes. I found that the form had printed out on Pay Check Printers! And Billing Printers! “UH OH!” quickly changed to “OH NO!” When I read comments like “Under no circumstances print anything on this Printer Again!!!!” I realized I had really messed things up. By changing the font size and the quality settings, the billing, payroll and work order printers all had to be manually reset and the jobs that printed out paychecks, customer bills and employee work orders had to be re-run!
After taking all the forms out of their envelopes, the stack of papers was over 4 inches thick, just to give you an idea about how many responses we had.
A couple of hours later, Tom Gibson called me to his office. “Uh Oh.” (remember… One “uh oh” erases all previous “atta boy”s). When I entered Tom’s office, I could tell that something was definitely wrong. Like I mentioned earlier. Tom’s ears were beet red…. and in case you don’t know what a beet looks like. Here is one:
The same color of Tom Gibson’s ears
Of course… I knew what this was all about, only I didn’t know yet, how Tom had found out about it…. Tom began by saying…. “Ron Kilman just received a call from James Harlow asking him who is Kevin Breazile and why is he printing something out on my printer? Ron didn’t like the fact that he wasn’t aware that you had sent something to the President of the Company’s printer.
James G. Harlow Jr.
Sorry. That’s the biggest picture I could find of James Harlow….
Um what could I say? So, I said this…
Well. This was a quality idea that our team had. We wanted to collect the names of people that used each printer so that we could send in a proposal to have the printer ID added in the Corporate Directory.
I didn’t mention that Harlow’s Secretary had returned the form with all the people that used his computer as I had requested, because I knew that the President of the Electric Company was not asking because he was upset that I had printed something out on his printer. No. He had probably been told that the reason the bills were late being sent to the one million customers that month was because some kook had messed up their printers and the jobs had to be run over again causing the delay. So, I thought it was best not to go that route…
So, I stuck with my story, which was the truth…. I had printed out the forms on all the printers as part of a quality idea by our CST. — I also didn’t mention that three years earlier, Tom had asked me to learn everything I could about the company computer, because he believe that the computer was going to be the wave of the future.
Even though Tom believed my explanation, he told me…. “Kevin, Ron never wants this to happen again, therefore, you are never to send anything out of this plant without Ron Kilman’s personal approval. Is that clear?”
I replied to Tom that this was unreasonable. I send things to other departments all the time. I send Substation Inspection forms, and blueprint revisions and all sorts of other forms downtown all the time. Ron Kilman wouldn’t want to waste his time approving all those things….
Tom thought about it and revised his statement…. “Then, don’t ever send out anything that isn’t part of your normal daily job without Ron’s approval first.” — Ok. I thought…. this works, since everything I do is part of my normal daily job…. Even printing out forms on all the printers in the company… since that was part of our normal “Quality Process” Customer Service Team activity…. So, I happily agreed. And I left Tom’s office happy that I hadn’t joined the ranks of the unemployed.
That was one thing about working at the plant at this time. As long as your heart was in the right place…. That is, you tried your best to keep the electricity humming through the electric lines…. then the chances of being fired for messing up, even as big of a mess up as this, most often didn’t end up by losing your job.
I sometimes think that this was my biggest mess up of all time… however…. after this episode was over… there was a part two to this story….. Believe it or not…. Someone else in the company was overjoyed about what I had just done. They had been trying to do something similar for a long time, only to be told that it was impossible. — Doing the Impossible… I was good at that… Part two of this story is a story for another day…
Working Smarter with Power Plant Dumb Terminals
After the reorganization at the coal-fired power plant in North Central Oklahoma during 1987, a bunch of new faces showed up at the plant. I mentioned in last week’s post that we had a new plant manager, Ron Kilman (See Post: “From Pioneers to Power Plant Managers“). In that post I also mentioned that the PC age was rapidly growing and I had bought a computer of my own and was eager to learn more. The Electrical Supervisor, Leroy Godfrey had retired, and was replaced by a guy named Tom Gibson. Tom was a good supervisor who was willing to think out of the box.
Tom gave me one of my first assignments directly by calling me to his office. Well, Leroy had never really called me to his office before. When Leroy wanted to chew you out, he was happy to come down to the Electric Shop and do it, so I didn’t really know what to expect by being “called to his office”. Believe me… it wasn’t the last time he had “called me to his office.” But it was the most satisfying time. Mainly because this time, when I arrived, Tom’s face wasn’t beet red with anger like it was on one later occasion.
This is what Tom told me to do… He said that we needed to install computer terminals all over the plant. They had a chart where they wanted the terminals to go. There were about 15 locations all over the plant including the coalyard which was about 1/2 mile from the main plant. Along with those, there were a bunch of IBM Network printers that needed to be installed with the terminals.
Then Tom told me the best part. He wanted me to do it all myself. Then he told me an even better part…. He said, (and I quote) “I want you to learn everything you can about this computer stuff. I think it will come in handy.” As my friend Stephen Todd at Dell would say, “That was the ‘Keys to the Kingdom”. I told him I would be glad to do everything he asked.
That last part later came back to haunt Tom…. but he did tell me…. learn “everything” I could about the computer. When he was referring to “The Computer”, he was talking about the company mainframe, a Honeywell system that resided in Oklahoma City at Corporate Headquarters.
A Honeywell Mainframe computer
The Terminals I was going to install were called “Dumb terminals”. they weren’t computers, they were just monitors with a keyboard that connected directly to a switch back in the telephone room that was connected via a microwave link directly to Oklahoma City and the Honeywell system:
A DEC terminal like this.
So, when I returned to the electric shop, I began my “hacker” apprenticeship. One that would later allow me to harass Gene Day in the Control Room, confuse Dick Dale in the warehouse, cause headaches for the IT department downtown, and finally cause the President of the Electric Company to personally call our Plant Manager Ron asking who was this guy Kevin Breazile! Hence the reason for Tom Gibson’s beet red face a few years later. But that is another story for another time.
I had two things right away that I had to figure out. How was I going to run cables from the telephone room in the office to each of the places around the plant that needed a computer terminal and what are these funny connectors and what do I need to do with them?
A Modular DB25M to RJ45 Adapter
Ok, so I figured they plugged in the back of the terminal and then there was a Cat1 cable (no, not a Cat3, a Cat1) that plugged into that, and needed to plug into a jack in the wall that I was going to have to install. They called these funny connectors “Hoods”. The 25 pin Hoods that we used were blue. We had 9 pin hoods also that we used for the actual PCs that the clerks and the chemist were using. They had an emulator program to make them act like a dumb terminal:
A Serial RS232-DB9 9-Pin Female to RJ45 Adapter
In an early post called “Power Plant Men’s Club Prizes and a Story of Luck” I explained how I have always been cursed with being very lucky. Well, that’s what some may call it, but I prefer to believe that one of my best friends St. Anthony helps me out at certain times. Well, this was one time when I asked for his assistance. St. Anthony of Padua is considered the Patron Saint of lost items. So, I asked him to help me figure out how I was going to do all this work in a reasonable amount of time.
St. Anthony of Padua
As is often the case, St. Anthony pointed me in the right direction. This particular day, he told me to tell my problem to Charles Foster. My close friend and one of the two Electric Shop foremen (not mine. I was working for Andy Tubbs). So, during lunch I told him what Tom Gibson told me to do, and showed him the blueprints where they wanted the terminals placed throughout the plant.
One of the places that needed a terminal was right there in the electric shop office. Charles looked around the office and said, “You know what? there used to be an old intercom system in this office that I think goes up to the telephone room. In fact, I think all the intercoms that were originally installed in the plant went to the telephone room.”
An old intercom sort of like this only older and in a box that sat on the desk and it had more switches
I vaguely remembered the intercoms when I was working as a summer help as there used to be an old box sitting in the garage when I worked for Stanley Elmore. They were later cut out and removed, because it wasn’t really practical and so it wasn’t used. Charles told me to start there, because there were intercoms everywhere.

If I had bought it a few years later it might have been called “Dumb Terminals for Dummies”, but the Dummies books hadn’t come around yet.
I have since thrown that book away after using it for years to prop up the corner of our sofa bed for the times when my mom would come and visit and she would sleep on the bed, only it had a broken bracket, and the Networking book was just the right thickness to level the bed….

I know that many of you are so bored out of your gourd that you have already stopped reading before you have reached this sentence…. I suppose those of you that are still following along are wondering “Why?”

Right now, they were just “Dumb Terminals” and that’s what a lot of the operators and maintenance people thought… they are just dumb…
I, on the other hand was in hog heaven. You see. I had called downtown to the IT department and asked to get a user name so that I could log directly into the mainframe. After all, my supervisor Tom had told me to learn “everything” I could about “this computer”. So, I took him up on it. I quickly was learning UNIX commands, though at the time, I didn’t know that’s what they were called.
I began learning the Computer language called “A” before I realized there was a “B” language and a “C” language, and that C was the one that was really used at the time. As it turned out the mainframe had manuals for everything right on it. That is how I was able to cause so much trouble the next few years.
Oh, and one more interesting thing I discovered on the mainframe. It had this interesting feature called “Email”. Yeah. Only, after figuring out how to pull up a list of all the emails on the system I found that there was only a handful of people that actually had e-mail addresses. So, the only person I would email on the mainframe was an engineer named Craig Henry. I had met him briefly once, but in the next few years, he was a valuable source of information. Email seemed like a great idea, but what good was it if there was only a few people you could send an email?
As for Craig Henry… As Humphrey Bogart said to Claude Rains in Casablanca, “This is the beginning of a Beautiful Friendship.” Come to think of it… Craig Henry sort of reminds me of Claude Rains… I must admit, I learned a lot more from him than he ever learned from me.

Shenanigans by way of computers…👿 …your good intentions may have backfired, but I have to give you kudos for your dedication and your ‘nerdiness (I mean that as a compliment, by the way).

On the record – Harlow made me promise it would never happen again. Off the record – I thought it was funny (unintended consequences always accompany “improvements”). Harlow surely knew that.
