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.
Do Power Plant Men and Corporate Headquarters Mix?

August 6, 1996 in Corporate Headquarters America, jaws began dropping a few minutes before 8 a.m. At first the security guard just thought some Power Plant Giant had taken a wrong turn and showed up at Corporate Headquarters to ask for directions. When another one showed up, this time carrying his Playmate lunch box, hard hat on his head, and lip quivering looking for a handy spittoon, the men in their suits and women in their fine dresses began running for cover. That was the day eight Power Plant Men took over the floor in the building where the Corporate Engineers usually lived.
If you want to understand the shock that emanated throughout the building, just picture the following bunch showing up on your doorstep:
Guardians of the Galaxy acting like Power Plant Men!
We had come from the four corners of the Oklahoma Electric Company Power Plant Kingdom and we were there in Oklahoma City because Corporate America needed our help! Two Power Plant Men from each of the main Power Plants were picked to help the company transition from the old Mainframe computer system to a new computer application called SAP. SAP was going to combine all of our computer needs into one big application that runs on the new computer network.
SAP Logo
Ernst and Young was the consulting company that was helping us install and implement SAP at our company. The company began the implementation some time in March, and the big bang go live date was going to be January 1, 1997. According to Ernst and Young, this was a physical impossibility. There was no way we could convert all of our requirements into SAP realities in such a short time.
The Maintenance Module for SAP hadn’t even been fully developed. We were actually working with SAP to design the module. Our company had demonstrated how a Best In Class Maintenance process worked, and SAP was designing their module around our needs. Everyone insisted that our aggressive timeline was too unreasonable and would never be met.
The Electric Company in Central Oklahoma had one Ace up their sleeve (well, maybe more than one)… That was “Power Plant Men!” As I mentioned in last week’s post (See the post “Destruction of a Power Plant God“), I was told on Monday, August 5, to show up for work the following day in Oklahoma City to work for 10 weeks on an SAP project.
Mike Gibbs, a mechanic from our plant was going with me. Our task was to convert all the Power Plant parts in the Inventory system in searchable strings that had a limited number of characters. Mike Gibbs used to work in the warehouse, so he was a good candidate for knowing what odd parts actually were.
Mike Gibbs
We were a cross-section of mechanics and electricians, and warehouse people. To give you an idea of how big our job was, we had over 100,000 different parts in the system. 75,000 of those parts were in the warehouse at the power plant where I worked. There were over 5,000 different types of Nuts and Bolts… just to give you an idea of the task ahead of us.
Ernst and Young said the task would take the eight regular employees four months to complete the task. The Electric Company said, “Power Plant Men can do it in 10 weeks.
We were able to use the office space used by all of the engineers because they all happened to be at the Coal-fired Power Plant in North Central Oklahoma where I normally worked because of the big explosion that destroyed part of the Turbine Generator room early Monday morning. While they packed up to begin the work of reconstruction, Mike and I packed up and headed to Oklahoma City.
Most of the “out-of-town” Power Plant Men stayed in hotels for the next 2 1/2 months, but Mike Gibbs and I decided that we couldn’t be away from our families that long, so we decided that we would drive back and forth to work each day from Stillwater, Oklahoma. This was about an hour drive with going to work traffic. We would meet in the parking lot of a Mexican Restaurant at the edge of town and take turns each day driving to Oklahoma City.
Normally, in an instance like this, we would get paid a mileage that was farther than if we drove to the plant and maybe even driving time to and from work each day, but when our Plant Manager Bill Green found out we were driving back and forth, he refused to pay us anything. He told us that it was far enough away that he would only pay for us to stay in a Hotel (which would have cost more than the mileage), he wouldn’t pay us mileage or even a per diem (which is a daily amount for expenses).
Bill Green knew that we were family men that wouldn’t want to be away from our families during the week if it was only an hour drive, so he played his card and said that we had to stay in a hotel, and he would pay the expense for that or he would pay nothing and we could drive back and forth all we wanted at our own expense, already knowing that we would rather wear our cars out and pay the extra gas each day to be with our families. I just thought this was pay back for me being so rotten all the time.
The first week I was there, I worked on converting the 5,000 different nuts, bolts and screws into cryptic search strings that all began with the three letter search word for bolt: BLT. If you wanted to search for a Bolt in the SAP inventory, you would know it begins with a the letters BLT. This only made me hungry all week, because to me, a BLT was a sandwich. A mighty good one too, I may add.
Power Plant Man sized Bacon Lettuce and Tomato Sandwich
After the first week, it was decided that having Power Plant Men roaming around between offices asking each other questions about parts was a hazard waiting to happen, so the engineer that was running our project Mark Romano had a special holding pen… um… I mean, cubicle built just for us. It was decided that we should all be together in what is called a “Bullpen Cube”. All nine of us. Bullpen was a good name considering that there was a lot of bull going around for all of us.
There were nine, because a young Corporate executive had been assigned to help us with all things “Corporate”. His name is Kent Norris. He was lucky enough to stay behind to work with us, instead of having to go spend the next 2 1/2 months at our plant up north helping to repair the fire damage.
Well. I say lucky. Lucky for us, maybe not for him. After all, he was someone from “corporate” stuck in a cubicle with 8 rascally Power Plant Men that kept themselves motivated by playing practical jokes on whoever was willing to fall for them. Not ever having experienced the likes of us before, Kent was in for 2 1/2 months of relentless practical jokes being played at his expense.
I must say that we had a terrific time teasing poor Kent, but he was such fun and took our jokes so well, that we could only admire his resilience to bounce back and smile after we ran him ragged with one joke after the next. I will go into more detail about the jokes we played on Kent in a later post. For now, I am just mentioning our situation, so that you can get a picture of our situation.
Kent helped us with our expense reports each week, and showed us all the good places to eat lunch. He helped us adapt to corporate life. He even showed us how to use our temporary badges to badge in and out of the doors when we entered and left the building.
Mike Gibbs discovered a better way. He just put his badge in his wallet, and since he was tall enough, when he walked up to the badge reader, he just pressed the back pocket of his blue jeans against the badge reader, and voila! The door would open like magic! Onlookers were always staring at this strange assortment of men in blue jeans and tee shirts walking through the office building during lunch.
I tried to remember all the people that were there in the cube with us… I remember that I was there, and so was Mike Gibb from the coal-fired Power Plant in North Central Oklahoma.
Our Coal Fired Power Plant
Ken Scott, who was the Maintenance Superintendent at the Gas-fired Power Plant by Konawa, and David Roe who worked in the warehouse at that plant.

Doyle Fullen, an Electric Foreman from the coal fired plant in Muskogee, and Robert Christy, a mechanic also from that plant.
Power Plant in Muskogee Oklahoma
I believe Dan Hayer, the warehouse man, was there from the gas-fired plant in Harrah, Oklahoma on a small lake called Horseshoe Lake. I don’t remember who else was there from that plant. I remember seeing someone there, but I think he was a more of a quiet type and for some reason, his name has escaped me.
Horseshoe Lake Plant as it looked back then
I was a sort of a computer programmer at this time, so I created small programs that would make our jobs easier. I created icons on the computers so that people didn’t have to log into the apps, and I created a couple of other small programs that just automated the monotonous manual steps that we would have to do over and over again as we plowed through the 100,000 different part descriptions.
After the first week, we had converted over 15,000 parts, and were on our way to meeting our goal.
So, how did we do? The Power Plant Men were able to convert all 100,000 parts in the inventory system to SAP in eight weeks! Two weeks ahead of schedule. This was typical for Power Plant Men, especially when you tell them it is impossible. This was another example of doing things that others said couldn’t be done.
I felt like a few people on our team were not too happy with me for creating things that made their job faster because they wanted to stay the full 10 weeks. Here we were in an air conditioned building working on computers all day instead of out in the heat and dirt.
We were all scheduled to go back to our home plants two weeks early when Mark Romano, our project manager came to our cube to give us the news… We had performed our job so well, they wanted to expand our scope. It seems that another department… I won’t mention which one, but their initials are T&D had been working on their measly 60,000 parts for the past 4 months and had only completed about 10,000 of them. They wanted to know if the Power Plant Men would be willing to give them a hand to convert the 50,000 parts in their inventory system the same way we did for Power Supply. Otherwise the go-live of January 1, would not be met since we were coming up to the end of September already.
Our Plant Managers had agreed that we could spend the next four weeks converting T&D’s parts as well, so of course, we agreed to stay on. I’m not sure if Corporate Headquarters was ever the same after that. Because we were able to stay on for the next four weeks, we were invited to an SAP banquet that we would have otherwise missed. We stood out like a sore thumb. I will write more about that banquet in a separate post as well as go into detail with some of the jokes that we played on Kent Norris.
Spending the 12 weeks in Corporate Headquarters was an important turning point in my career as a Power Plant Electrician. When we were in the bullpen cube, I was sitting in a chair where I could turn my head to the right and look out a window over the parking lot for the building. During the day I would watch people walking to-and-fro going about their business.
I had worked most of my adult life up to that point at a plant out in the country where when you climbed to the top of the 500 foot smoke stack and looked around, you could see fields and trees for 20 miles in any direction. Looking out that window at people made a big impression on me. Here I was sitting in an air conditioned office. No Coal Dust. No Fly Ash. No ear plugs to deafen the sound of steam shooting through the pipes turning the turbines. No 100 degrees in the summer. No freezing my fingers off in the winter. Just Power Plant Men quietly tapping on their computer keyboards, while they played jokes on Corporate Executive Kent. — This was the life.
I thought… things don’t get better than this. I was in computer heaven. Even though it was unconscious at the time, something stirred in me that thought… maybe… just maybe, I’m ready for a change…. I’ll wait and see what God wants me to do…
Comments from previous posts
Trust me. I experienced the four stages of grief before I accepted the reality of my situation. 🙂
Mike Gibbs looks like the kind of guy anyone would like to work with. The BLT looks wonderful even down to the last ounce of fatty substances know by medical science to clog arteries and all those smaller items adjoining them. BUT the main fact is that you chose GOD to help make your decision, Kudos and all to you for that!

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.
Do Power Plant Men and Corporate Headquarters Mix?
August 6, 1996 in Corporate Headquarters America, jaws began dropping a few minutes before 8 a.m. At first the security guard just thought some Power Plant Giant had taken a wrong turn and showed up at Corporate Headquarters to ask for directions. When another one showed up, this time carrying his Playmate lunch box, hard hat on his head, and lip quivering looking for a handy spittoon, the men in their suits and women in their fine dresses began running for cover. That was the day eight Power Plant Men took over the floor in the building where the Corporate Engineers usually lived.
If you want to understand the shock that emanated throughout the building, just picture the following bunch showing up on your doorstep:
Guardians of the Galaxy acting like Power Plant Men!
We had come from the four corners of the Oklahoma Electric Company Power Plant Kingdom and we were there in Oklahoma City because Corporate America needed our help! Two Power Plant Men from each of the main Power Plants were picked to help the company transition from the old Mainframe computer system to a new computer application called SAP. SAP was going to combine all of our computer needs into one big application that runs on the new computer network.
SAP Logo
Ernst and Young was the consulting company that was helping us install and implement SAP at our company. The company began the implementation some time in March, and the big bang go live date was going to be January 1, 1997. According to Ernst and Young, this was a physical impossibility. There was no way we could convert all of our requirements into SAP realities in such a short time.
The Maintenance Module for SAP hadn’t even been fully developed. We were actually working with SAP to design the module. Our company had demonstrated how a Best In Class Maintenance process worked, and SAP was designing their module around our needs. Everyone insisted that our aggressive timeline was too unreasonable and would never be met.
The Electric Company in Central Oklahoma had one Ace up their sleeve (well, maybe more than one)… That was “Power Plant Men!” As I mentioned in last week’s post (See the post “Destruction of a Power Plant God“), I was told on Monday, August 5, to show up for work the following day in Oklahoma City to work for 10 weeks on an SAP project.
Mike Gibbs, a mechanic from our plant was going with me. Our task was to convert all the Power Plant parts in the Inventory system in searchable strings that had a limited number of characters. Mike Gibbs used to work in the warehouse, so he was a good candidate for knowing what odd parts actually were.
Mike Gibbs
We were a cross-section of mechanics and electricians, and warehouse people. To give you an idea of how big our job was, we had over 100,000 different parts in the system. 75,000 of those parts were in the warehouse at the power plant where I worked. There were over 5,000 different types of Nuts and Bolts… just to give you an idea of the task ahead of us.
Ernst and Young said the task would take the eight regular employees four months to complete the task. The Electric Company said, “Power Plant Men can do it in 10 weeks.
We were able to use the office space used by all of the engineers because they all happened to be at the Coal-fired Power Plant in North Central Oklahoma where I normally worked because of the big explosion that destroyed part of the Turbine Generator room early Monday morning. While they packed up to begin the work of reconstruction, Mike and I packed up and headed to Oklahoma City.
Most of the “out-of-town” Power Plant Men stayed in hotels for the next 2 1/2 months, but Mike Gibbs and I decided that we couldn’t be away from our families that long, so we decided that we would drive back and forth to work each day from Stillwater, Oklahoma. This was about an hour drive with going to work traffic. We would meet in the parking lot of a Mexican Restaurant at the edge of town and take turns each day driving to Oklahoma City.
Normally, in an instance like this, we would get paid a mileage that was farther than if we drove to the plant and maybe even driving time to and from work each day, but when our Plant Manager Bill Green found out we were driving back and forth, he refused to pay us anything. He told us that it was far enough away that he would only pay for us to stay in a Hotel (which would have cost more than the mileage), he wouldn’t pay us mileage or even a per diem (which is a daily amount for expenses).
Bill Green knew that we were family men that wouldn’t want to be away from our families during the week if it was only an hour drive, so he played his card and said that we had to stay in a hotel, and he would pay the expense for that or he would pay nothing and we could drive back and forth all we wanted at our own expense, already knowing that we would rather wear our cars out and pay the extra gas each day to be with our families. I just thought this was pay back for me being so rotten all the time.
The first week I was there, I worked on converting the 5,000 different nuts, bolts and screws into cryptic search strings that all began with the three letter search word for bolt: BLT. If you wanted to search for a Bolt in the SAP inventory, you would know it begins with a the letters BLT. This only made me hungry all week, because to me, a BLT was a sandwich. A mighty good one too, I may add.
Power Plant Man sized Bacon lettuce and Tomato Sandwich
After the first week, it was decided that having Power Plant Men roaming around between offices asking each other questions about parts was a hazard waiting to happen, so the engineer that was running our project Mark Romano had a special holding pen… um… I mean, cubicle built just for us. It was decided that we should all be together in what is called a “Bullpen Cube”. All nine of us. Bullpen was a good name considering that there was a lot of bull going around for all of us.
There were nine, because a young Corporate executive had been assigned to help us with all things “Corporate”. His name is Kent Norris. He was lucky enough to stay behind to work with us, instead of having to go spend the next 2 1/2 months at our plant up north helping to repair the fire damage.
Well. I say lucky. Lucky for us, maybe not for him. After all, he was someone from “corporate” stuck in a cubicle with 8 rascally Power Plant Men that kept themselves motivated by playing practical jokes on whoever was willing to fall for them. Not ever having experienced the likes of us before, Kent was in for 2 1/2 months of relentless practical jokes being played at his expense.
I must say that we had a terrific time teasing poor Kent, but he was such fun and took our jokes so well, that we could only admire his resilience to bounce back and smile after we ran him ragged with one joke after the next. I will go into more detail about the jokes we played on Kent in a later post. For now, I am just mentioning our situation, so that you can get a picture of our situation.
Kent helped us with our expense reports each week, and showed us all the good places to eat lunch. He helped us adapt to corporate life. He even showed us how to use our temporary badges to badge in and out of the doors when we entered and left the building.
Mike Gibbs discovered a better way. He just put his badge in his wallet, and since he was tall enough, when he walked up to the badge reader, he just pressed the back pocket of his blue jeans against the badge reader, and voila! The door would open like magic! Onlookers were always staring at this strange assortment of men in blue jeans and tee shirts walking through the office building during lunch.
I tried to remember all the people that were there in the cube with us… I remember that I was there, and so was Mike Gibb from the coal-fired Power Plant in North Central Oklahoma.

I believe Dan Hayer, the warehouse man, was there from the gas-fired plant in Harrah, Oklahoma on a small lake called Horseshoe Lake. I don’t remember who else was there from that plant. I remember seeing someone there, but I think he was a more of a quiet type and for some reason, his name has escaped me.
Horseshoe Lake Plant as it looked back then
I was a sort of a computer programmer at this time, so I created small programs that would make our jobs easier. I created icons on the computers so that people didn’t have to log into the apps, and I created a couple of other small programs that just automated the monotonous manual steps that we would have to do over and over again as we plowed through the 100,000 different part descriptions.
After the first week, we had converted over 15,000 parts, and were on our way to meeting our goal.
So, how did we do? The Power Plant Men were able to convert all 100,000 parts in the inventory system to SAP in eight weeks! Two weeks ahead of schedule. This was typical for Power Plant Men, especially when you tell them it is impossible. This was another example of doing things that others said couldn’t be done.
We were all scheduled to go back to our home plants two weeks early when Mark Romano, our project manager came to our cube to give us the news… We had performed our job so well, they wanted to expand our scope. It seems that another department… I won’t mention which one, but their initials are T&D had been working on their measly 60,000 parts for the past 4 months and had only completed about 10,000 of them. They wanted to know if the Power Plant Men would be willing to give them a hand to convert the 50,000 parts in their inventory system the same way we did for Power Supply. Otherwise the go-live of January 1, would not be met since we were coming up to the end of September already.
Our Plant Managers had agreed that we could spend the next four weeks converting T&D’s parts as well, so of course, we agreed to stay on. I’m not sure if Corporate Headquarters was ever the same after that. Because we were able to stay on for the next four weeks, we were invited to an SAP banquet that we would have otherwise missed. We stood out like a sore thumb. I will write more about that banquet in a separate post as well as go into detail with some of the jokes that we played on Kent Norris.
Spending the 12 weeks in Corporate Headquarters was an important turning point in my career as a Power Plant Electrician. When we were in the bullpen cube, I was sitting in a chair where I could turn my head to the right and look out a window over the parking lot for the building. During the day I would watch people walking to-and-fro going about their business.
I had worked most of my adult life up to that point at a plant out in the country where when you climbed to the top of the 500 foot smoke stack and looked around, you could see fields and trees for 20 miles in any direction. Looking out that window at people made a big impression on me. Here I was sitting in an air conditioned office. No Coal Dust. No Fly Ash. No ear plugs to deafen the sound of steam shooting through the pipes turning the turbines. No 100 degrees in the summer. No freezing my fingers off in the winter. Just Power Plant Men quietly tapping on their computer keyboards, while they played jokes on Corporate Executive Kent. — This was the life.
I thought… things don’t get better than this. I was in computer heaven. Even though it was unconscious at the time, something stirred in me that thought… maybe… just maybe, I’m ready for a change…. I’ll wait and see what God wants me to do…
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.

We were all scheduled to go back to our home plants two weeks early when Mark Romano, our project manager came to our cube to give us the news… We had performed our job so well, they wanted to expand our scope. It seems that another department… I won’t mention which one, but their initials are T&D had been working on their measly 60,000 parts for the past 4 months and had only completed about 10,000 of them. They wanted to know if the Power Plant Men would be willing to give them a hand to convert the 50,000 parts in their inventory system the same way we did for Power Supply. Otherwise the go-live of January 1, would not be met since we were coming up to the end of September already.
Our Plant Managers had agreed that we could spend the next four weeks converting T&D’s parts as well, so of course, we agreed to stay on. I’m not sure if Corporate Headquarters was ever the same after that. Because we were able to stay on for the next four weeks, we were invited to an SAP banquet that we would have otherwise missed. We stood out like a sore thumb. I will write more about that banquet in a separate post as well as go into detail with some of the jokes that we played on Kent Norris.
Spending the 12 weeks in Corporate Headquarters was an important turning point in my career as a Power Plant Electrician. When we were in the bullpen cube, I was sitting in a chair where I could turn my head to the right and look out a window over the parking lot for the building. During the day I would watch people walking to-and-fro going about their business.
I had worked most of my adult life up to that point at a plant out in the country where when you climbed to the top of the 500 foot smoke stack and looked around, you could see fields and trees for 20 miles in any direction. Looking out that window at people made a big impression on me. Here I was sitting in an air conditioned office. No Coal Dust. No Fly Ash. No ear plugs to deafen the sound of steam shooting through the pipes turning the turbines. No 100 degrees in the summer. No freezing my fingers off in the winter. Just Power Plant Men quietly tapping on their computer keyboards, while they played jokes on Corporate Executive Kent. — This was the life.
I thought… things don’t get better than this. I was in computer heaven. Even though it was unconscious at the time, something stirred in me that thought… maybe… just maybe, I’m ready for a change…. I’ll wait and see what God wants me to do…
Do Power Plant Men and Corporate Headquarters Mix?
August 6, 1996 in Corporate Headquarters America, jaws began dropping a few minutes before 8 a.m. At first the security guard just thought some Power Plant Giant had taken a wrong turn and showed up at Corporate Headquarters to ask for directions. When another one showed up, this time carrying his Playmate lunch box, hard hat on his head, and lip quivering looking for a handy spittoon, the men in their suits and women in their fine dresses began running for cover. That was the day eight Power Plant Men took over the floor in the building where the Corporate Engineers usually lived.
If you want to understand the shock that emanated throughout the building, just picture the following bunch showing up on your doorstep:
Guardians of the Galaxy acting like Power Plant Men!
We had come from the four corners of the Oklahoma Electric Company Power Plant Kingdom and we were there in Oklahoma City because Corporate America needed our help! Two Power Plant Men from each of the main Power Plants were picked to help the company transition from the old Mainframe computer system to a new computer application called SAP. SAP was going to combine all of our computer needs into one big application that runs on the new computer network.
SAP Logo
Ernst and Young was the consulting company that was helping us install and implement SAP at our company. The company began the implementation some time in March, and the big bang go live date was going to be January 1, 1997. According to Ernst and Young, this was a physical impossibility. There was no way we could convert all of our requirements into SAP realities in such a short time.
The Maintenance Module for SAP hadn’t even been fully developed. We were actually working with SAP to design the module. Our company had demonstrated how a Best In Class Maintenance process worked, and SAP was designing their module around our needs. Everyone insisted that our aggressive timeline was too unreasonable and would never be met.
The Electric Company in Central Oklahoma had one Ace up their sleeve (well, maybe more than one)… That was “Power Plant Men!” As I mentioned in last week’s post (See the post “Destruction of a Power Plant God“), I was told on Monday, August 5, to show up for work the following day in Oklahoma City to work for 10 weeks on an SAP project.
Mike Gibbs, a mechanic from our plant was going with me. Our task was to convert all the Power Plant parts in the Inventory system in searchable strings that had a limited number of characters. Mike Gibbs used to work in the warehouse, so he was a good candidate for knowing what odd parts actually were.
Mike Gibbs
We were a cross-section of mechanics and electricians, and warehouse people. To give you an idea of how big our job was, we had over 100,000 different parts in the system. 75,000 of those parts were in the warehouse at the power plant where I worked. There were over 5,000 different types of Nuts and Bolts… just to give you an idea of the task ahead of us.
Ernst and Young said the task would take the eight regular employees four months to complete the task. The Electric Company said, “Power Plant Men can do it in 10 weeks.
We were able to use the office space used by all of the engineers because they all happened to be at the Coal-fired Power Plant in North Central Oklahoma where I normally worked because of the big explosion that destroyed part of the Turbine Generator room early Monday morning. While they packed up to begin the work of reconstruction, Mike and I packed up and headed to Oklahoma City.
Most of the “out-of-town” Power Plant Men stayed in hotels for the next 2 1/2 months, but Mike Gibbs and I decided that we couldn’t be away from our families that long, so we decided that we would drive back and forth to work each day from Stillwater, Oklahoma. This was about an hour drive with going to work traffic. We would meet in the parking lot of a Mexican Restaurant at the edge of town and take turns each day driving to Oklahoma City.
Normally, in an instance like this, we would get paid a mileage that was farther than if we drove to the plant and maybe even driving time to and from work each day, but when our Plant Manager Bill Green found out we were driving back and forth, he refused to pay us anything. He told us that it was far enough away that he would only pay for us to stay in a Hotel (which would have cost more than the mileage), he wouldn’t pay us mileage or even a per diem (which is a daily amount for expenses).
Bill Green knew that we were family men that wouldn’t want to be away from our families during the week if it was only an hour drive, so he played his card and said that we had to stay in a hotel, and he would pay the expense for that or he would pay nothing and we could drive back and forth all we wanted at our own expense, already knowing that we would rather wear our cars out and pay the extra gas each day to be with our families. I just thought this was pay back for me being so rotten all the time.
The first week I was there, I worked on converting the 5,000 different nuts, bolts and screws into cryptic search strings that all began with the three letter search word for bolt: BLT. If you wanted to search for a Bolt in the SAP inventory, you would know it begins with the letters BLT. This only made me hungry all week, because to me, a BLT was a sandwich. A mighty good one too, I may add.
Power Plant Man sized Bacon lettuce and Tomato Sandwich
After the first week, it was decided that having Power Plant Men roaming around between offices asking each other questions about parts was a hazard waiting to happen, so the engineer that was running our project Mark Romano had a special holding pen… um… I mean, cubicle built just for us. It was decided that we should all be together in what is called a “Bullpen Cube”. All nine of us.
There were nine, because a young Corporate executive had been assigned to help us with all things “Corporate”. His name is Kent Norris. He was lucky enough to stay behind to work with us, instead of having to go spend the next 2 1/2 months at our plant up north helping to repair the fire damage.
Well. I say lucky. Lucky for us, maybe not for him. After all, he was someone from “corporate” stuck in a cubicle with 8 rascally Power Plant Men that kept themselves motivated by playing practical jokes on whoever was willing to fall for them. Not ever having experienced the likes of us before, Kent was in for 2 1/2 months of relentless practical jokes being played at his expense.
I must say that we had a terrific time teasing poor Kent, but he was such fun and took our jokes so well, that we could only admire his resilience to bounce back and smile after we ran him ragged with one joke after the next. I will go into more detail about the jokes we played on Kent in a later post. For now, I am just mentioning our situation, so that you can get a picture of our situation.
Kent helped us with our expense reports each week, and showed us all the good places to eat lunch. He helped us adapt to corporate life. He even showed us how to use our temporary badges to badge in and out of the doors when we entered and left the building.
Mike Gibbs discovered a better way. He just put his badge in his wallet, and since he was tall enough, when he walked up to the badge reader, he just pressed the back pocket of his blue jeans against the badge reader, and voila! The door would open like magic! Onlookers were always staring at this strange assortment of men in blue jeans and tee shirts walking through the office building during lunch.
I tried to remember all the people that were there in the cube with us… I remember that I was there, and so was Mike Gibb from the coal-fired Power Plant in North Central Oklahoma.

I believe Dan Hayer, the warehouse man, was there from the gas-fired plant in Harrah, Oklahoma on a small lake called Horseshoe Lake. I don’t remember who else was there from that plant. I remember seeing someone there, but I think he was a more of a quiet type and for some reason, his name has escaped me.
Horseshoe Lake Plant as it looked back then
I was a sort of a computer programmer at this time, so I created small programs that would make our jobs easier. I created icons on the computers so that people didn’t have to log into the apps, and I created a couple of other small programs that just automated the monotonous manual steps that we would have to do over and over again as we plowed through the 100,000 different part descriptions.
After the first week, we had converted over 15,000 parts, and were on our way to meeting our goal.
So, how did we do? The Power Plant Men were able to convert all 100,000 parts in the inventory system to SAP in eight weeks! Two weeks ahead of schedule. This was typical for Power Plant Men, especially when you tell them it is impossible. This was another example of doing things that others said couldn’t be done.

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.

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. 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.

My hat’s off to you! You handled Bill’s refusal to pay for your travel expense much better than I would have.
