Texas Company's Antique Computers Are For Production, Not Display
concealment writes "Sparkler Filters up north in Conroe [Texas] still uses an IBM 402 in conjunction with a Model 129 key punch – with the punch cards and all – to do company accounting work and inventory. The company makes industrial filters for chemical plants and grease traps. Lutricia Wood is the head accountant at Sparkler and the data processing manager. She went to business school over 40 years ago in Houston, and started at Sparkler in 1973. Back then punch cards were still somewhat state of the art."
See kottke.org for an eye-popping view of one of the "programs" — imagine debugging that.
"THAT", (a wired board), is vastly easier to debug than any modern software. In fact a trainee can usually debug it by trial an error in just a few minutes.

My working C=64 ain't got nothing on this fine machine.
Hideki!
That shouldn't shock anyone who's dealt with PLCs.
or a parts cost more then a full new system
I wouild rather use this than trusting Microsoft products to manage my accounts
Yeah, so did I. You were supposed to use the last 6 columns for a number that you could use in sorting the cards. We also used markers so you could line up the cards based on the position of a diagonal stripe on the edge. PL/1 - what a language! I had to write an assembler in PL/1. It was a great way to learn what we used to call "structured programming".
My dad had an Altair 8080 CP/M machine that he build in 75 and ran in his business until well after the turn of the century.
That why you use sequence numbers in 73-80. Been there, done that. But only did it once.

Learned quickly to run a magic marker squiggly line over the top of those card decks...
"If it ain't broke, don't replace it. Even if replacing it would lead to a 3 fold increase in employee productivity."
A few other folks posted something similar above at the same time.
Anyway, if I were in charge, here's what I'd do:
Look at the power consumption of the machine. It's probably a lot.
Have the accountant write the specs for what that was to do.
Buy the accountant ANY damn laptop they wanted.
Sell that old machine to some computer collector that would pay through the nose to acquire.
Profit. Or at least, it would compensate the costs of moving the system to something a little more modern - a MS Office App is probably all this company needs or an intranet web app.
Why upgrade?
That machine is gonna die one day.
Having something a little more modern will allow for growth and integration.
And now long would you have to run it to spend the same amount of money it takes to buy modern equipment and pay for someone to convert your accounting over?
I like "if it ain't broke" in general, but this thing has to be a massive power drain, and when it finally does break, they're likely going to be screwed.
While in college there was still a working punch card machine on campus. Our intro to computer science professor made us write our first program using punch cards. He said we would get two things out of it. We would understand why some things are the way they are with respect to programming languages and command lines. And we would have book marks for life (the program was short but we had to buy a deck of blanks at the bookstore). I still use these cards for bookmarks.
In 1973 a small company could buy a computer to keep books, so well it can still be used today, but just ten years earlier, NASA, with a budget of 6% of the USA's GDP, wasn't able to use computers to help design the F-1 engines?
I think that's the point here. It WORKS, so you don't have to. I'm sure all sorts of dipshit hipster technolibertardians are salivating at the mouth to replace a simple system that works with an iPad app and keeping all their data in a "cloud" service, increasing their costs a thousandfold, reducing the reliability of their systems and giving them more complexity for no gain other than to stay buzzword compliant and keep a sad bunch of brogrammers supplied with horn rimmed glasses and pabst for another week.
Company where I worked decided there perfectly fine AS/400 systems were not good enough and would save lots of money replacing the 20 year old system with SAP.
Hilarity ensued.
(and lots of 70 hour weeks... only 5% implemented with 15 years worth of projected savings already spent).
She was like chocolate when she drank... semi-sweet at first and then increasingly bitter.
Wouldn't the power savings of replacing the computer and all the peripherals justify the replacement of all that with even an entry level PC, from 10 years ago?
Kind of like mowing the lawn with a pair of scissors. Yeah, I'm sure it could be done.
I thought the Computer History Museum got that IBM 402. There's one in the Computer History Museum now. They may have the machine the company was using for parts.
Here it is running in Conroe, TX in 2011. (Terrible video, though)
And people bitch about XP users hanging onto an old and obsolete system.

I took an embedded systems course in university (Engineering Physics program)....we had to build boards up from components, write software in assembly, and then load it into the hardware and cause the hardware to do stuff.
My longest debug session was when I couldn't figure out why my software wasn't working properly...turned out that my team-mates had mis-wired the stepper motor. Once I figured out exactly how they had screwed up the wiring I was able to compensate in software and it worked perfectly.
That's an 026 keypunch he's leaning on, not a 129.
That's why smart people punched sequence numbers in columns 73-80. It helped if you had access to a card sorter, otherwise you'd incur machine time using the sort program to punch a new deck.
There was a lot of standalone electromechanical hardware (not just punches and sorters) to support punched card data processing - my mother (now 80) worked for a utility company in the 50s and alternated her time between doing data entry (card punch) and data verification - essentially retyping the data on a card verifier with the punched card in place to check the data entry was correct.
Actually, an early version of the IBM FORTRAN compiler (for a real computer) marked the cards according to the statement type on a lexical analysis pass and then sorted the cards by that field so it could load the compiler code that dealt with each particular type of statement in turn (the computer having very little memory). The generated code was then resorted to match the original program card sequence.
Yeah, BINDERE DUNDAT.
c. 1977, cutting my teath on "real programming" in Fortran, and CDC 6600 Assembler with punched cards (post HP2000 Basic -- everyone starts with Basic - in high school). We did have a few plugboard computers, including at least one analog computer, as well.
In Liberty, Rene
...that would take documentation of the plugboard wiring of the old 400 series "accounting machines" and produce source that would work exactly the same as the accounting machine, give 80-column card images for the data. It wouldn't emulate any cross-connects to other tab equipment (sorters, punches, interpreters) but it did a wonderful job of moving plug-board programming to the more modern computers (360, in particular). Anyone know where that software might be? As I recall, it was on a micro-spool of magnetic tape originally, purchased at user group meetings. Time to google...nothing so far...
They're paying a huge electricity bill to run a task and iPhone would run faster.
OK, I get it, Sparkler hates trees. But the insanity of someone protecting their job by never updating technology is just amazing. I would love to see what they have spent on maintenance over the years for that electromechanical junk. And I really wonder where they are getting punch cards. Can you even get them any more, or are they having a printer make custom batches for them? And, of course, there is no really useable backup of all of the company's data for when the inevitable final failure hits. For less than the cost of their next punch card order they could be on a modern system with performance and good data backup. But then I guess that Lutricia Wood might be concerned that others might be able to do thing that only the high priestess of data systems does now. Good thing that she will live forever and never retire, otherwise Sparkler would be in a very bad position.

And I thought my alma mater was out-of-touch running an IBM 7094 (w/ core in oil!) in 1976 as its main campus computer.
seeing people trip or drop stacks or boxes of cards on the floor and then crying
Grab a marker pen and draw some diagonal lines/crosses on the edges of the stack. You can easily see which ones are out of order.
You can also see if anybody has swapped a couple of them around as a "joke".
No sig today...
At this company, we use difference engines. And that's the way we like it!
But can it run crysis?
Let's load it up with 10,000+ punch cards.
It's not a matter of "if it ain't broke, don't fix it".
Even if it correctly does the computations it's supposed to do, it's doing it at a cost probably thousands of times of what it would cost with a non-obsolete system. Power costs, paying someone with the incredibly rare skill set needed to operate that machine, repair labor/costs, etc.
It's no different than, say, using manual labor to grow corn. Sure, it can be done, but at a cost manyfold of using modern techniques.
Replacing this dated equipment will also result in replacing operator, and that can have all kinds of hidden costs. If someone worked for your business for 40 years and is loyal and productive employee, then why do you care if they want to do it with punch cards or abacus? They had 40 years to prove that whatever they are doing works, unless there are new process requirements, there is no reason to change
Decision chart:
1. Did any processes change or about to change? Yes/No
Yes - Go To 3.
No - Go To 2.
2. Job gets done? Yes/No
Yes - leave it alone.
3. No - look into optimizing/fixing.
...of spaghetti code!
One critical irreplaceable part breaks, and they can no longer process payroll or inventory.
All because they don't want to hire somebody to spend a week or two to replace the functionality of that obscene waste of energy with a simple spreadsheet. The simple value of data security, not to mention the inter-operability between the data generated and things like, I dunno... check printing and direct deposit, for example, seems obvious.
I'd also guess there would be a lot less work for their accounting department. Either they could save the expense of one or two peoples' salaries, or at least spread the workload savings among the staff. In any event, it simply doesn't make sense not to modernize it.

The new system is easier to find guys who can do the work, and they will be more willing to work with you.

Dark Reflection
How much is the IBM support contract for this?
No offense AC, but there is an element of "stupid" to doing this. How are you going to fix it if it breaks, and more importantly, what will it cost? Also, the same thing could very likely be done with off the shelf commodity hardware and some cheap (or free) accounting software. Accounting productivity would be DRAMATICALLY increased just in the amount of time saved each day. Sounds to me like someone in that company is lacking some serious business sense. Punched cards had their day, but that day is long gone.
I went there when it was still called FTU. I remember the exact same thing. I remember seeing someone drop a large box of cards in the Florida rain which of course meant they lost everything. I went there 1977-78 ... when were you there?

Banks still using OS/2 Warp3 with custom programs and too expensive to replace. Using ISA boards, motherboards, and cpu's you can't find reliable replacement parts for.
Especially the ones that don't even need punch cards to run. Mechanical computers can handle everything from algebra to complex calculus, and are completely impervious to EMP or hacking (except, perhaps being literally hacked, like with a hacksaw).

IBM 402, 403 and 407's were tabulators not computers. As an old IBM program support rep., the first time I ran in to an RPG program it made no sense to me till I realized that RPG is nothing more than an emulation of a tabulator control panel.
This company is probably the only one in the area that will still be operational in case of a nuclear war. that type of computing device is pretty much impervious to EMPs.
Just sayin'. Bet lots of you wise-guys couldn't even figure out the manual.
Ran into a tools company in Texas that was still running an old Autocoder machine.
When they first told us about it they said: "Well its not really Autocoder, we're just doing it under emulation." They lied.
Thanks. That would have been real helpful 40 YEARS AGO!
The key to the whole thing was the rubber banded few cards at the front of the box that ran IEHSORT(?) on the sequence numbers of the rest of the box.
Yes, that was SOP when I was in college, but it only helps. It is often possible to swap two cards an not make a visible "jag" in the line. Still, it works pretty well.
I used to see people carrying multiple cardboard boxes of cards and was impressed until I learned that they were fairly simple COBOL programs. That is when I decided to never learn COBOL. Once saw a student crying after dropping a two tray COBOL deck on a windy day.

I had a very annoying related bug in a mainframe program once that took me forever to get to the bottom of, where a text parser I had written was getting the weirdest errors. Eventually I discovered that somewhere in between the input text file on disk and my program was a virtual card punch and virtual card reader - each line of text went through as a virtual punch card for legacy reasons - and the virtual card punch was being ever-so-helpful and automatically punching sequence numbers in 73-80!
Socialism: a lie told by totalitarians and believed by fools.
and then crying when they had try to reorder them to get their program to work
That was the tears, later came the laughter when CA's mainframe Librarian product would state:
"-END CARD MISSING - MAKE SURE DECK WAS NOT DROPPED"
Even though it was reading from disk or tape...
(This was about 20 years ago, As far as I know it still does this to this day)
Wouldn't it be easier to emulate this hardware? I mean, if anything went wrong with a hardware system like this, the business would cease to exist. Hire a college student to write an emulator (if there isn't one already) and get an emulator image that does the same thing this ancient hardware does. As an added bonus, the thing would probably run 1000x faster on a Pentium II, but that isn't the reason to emulate it. An enterprising programmer would be able to write a JCA layer and tie this system in with a modern web interface.

change for the sake of change. Let me say up front that i've worked in IT for over 15 years. Mostly as a DBA but I did network admin, hardware, development and OS.
I keep hearing how the next version will do X, save Y amount of time and Z money. Won't require as many people to maintain it, etc. Yet it never seems to be the case. Vendors keep us on a continuous upgrade cycle because bug fixes aren't back ported or to get the latest security patches, etc. Managers, architects seem to focus more on resume building than a stable environment.
I can't get any commitment for maintaining production but if i'm an hour late on a project task i'll have an army standing in my cubicle harassing me. I constantly hear developers wanting to go back to the basics because the new piece of software that's supposed to make their life easier isn't as stable.
Yes, I love to play with the latest and greatest features but i'm not sure if from the companies perspective if its always worth the money. I have to say working in IT support can be a very frustrating and stressful job.

Hell's Kitchen rules #42.
I used all that gear in high school and high school summer jobs. I've wired panels for an IBM 402, an IBM 407 (the last of the electromechanical accounting machines and the best one), a 514/519 reproducer (a 519 has a mark sense reader option), and the 77 and 84 collators. And, of course, card sorters and punches. I was able to draw graphs with a 402 and generate poetry with an 84 collator. This is pushing the limits of those machines.
The normal processing cycle for a sales/billing operation looks like this:
The card operations aren't that bad. All this stuff is slow, but automatic. The data entry is the labor-intensive part of the operation.
True. But you have to admit, much COBOL was stored on and run from 80-column or maybe IBM 96-column) cards. Boxes and boxes of them, given the amazingly low code density (i.e., verbosity) of the language.
I would venture here and now in the 21st Century COBOL is safely away from punched cards. However, my Air Force computer programming curriculum 30 years ago was 4 weeks (out of a 6-week class) of COBOL punched onto cards and run in batch mode. Rubber bands and the designated runner of the day to take the decks across the base (6 blocks) to the system room to be compiled and run.
You absolutely DID NOT use the compiler to check your syntax when your code-compile-checkout cycle was measured in hours and you had two days to complete a project. Fanatical desk checking was the rule of the day. And since the instructors were competitive assholes and introduced an under-the-table prize for the first in the class to complete the project, so was sabotage of everyone else's decks. The runner of the day was a hell of a job... wonderful opportunities for bribery and also threats.
Now get off my runway!
Welcome to the Panopticon. Used to be a prison, now it's your home.
The main cost of getting off of old systems is usually converting data to a newer format. Is there any bargain-basement way of doing that here? I am thinking of something like, using an arduino connected to the 402's printer port to capture data to a PC, and then having the 402 "print" all the old data. The 402's blazing print speed of "100 (80-column) lines per minute" doesn't sound fast enough to bury an Arduino or even a gen-1 USB connection.
:>D
I am not a professional programmer but I think if I knew the guy and liked him I might be willing to help for free--or at least, pretty darn cheap. The money involved has to be part of the issue here. Of course, maybe they only know how to create programs on the 402.... So what they'd really want is a 'virtual' 402 program, where they could change reports by 'wiring up' new on-screen programming boards.
Worked for the GOVT back in the late 80s, early 90s at the MEPS Center in Cleveland..
At that time they were still using reel to reel storage and punch cards!
Military Intelligence at its best :)
Really? We used to drag a marker across the top of the cards in a diagonal line from front to back. It was immediately obvious which cards were out of order.
And that, audience, is why sort routines were so popular back then.
deleting the extra space after periods so i can stay relevant, yeah.
That is what I meant.
It did originally.
The reason COBOL required indention originally (and the reason it generally no longer does) is because it was necessary for punch cards. The indention moved the holes to where the card parser could identify codes correctly.
The road to tyranny has always been paved with claims of necessity.
everything could equals punch card, my father did some FORTRAN on those cards....
But at some point you do have to move on. They have long since past this point. If they have a failure, they are screwed and will have to start from scratch, with a deadline looming over their heads.
I used an IBM 403 to run a Boy Scout mailing list in the early 1970s. It's the successor to the 402, and has 133 vertical bars with the character set on them, which slide into position based on the program and punch card data and then get whacked with a hammer to print. The kids and most of the adults weren't allowed to mess with the plug board on the side, but we could do anything we wanted with the paper-tape driver and the keypunch and card sorter, so there was still a fair bit of hacking room. (There was one adult who knew what he was doing with the wires.)
Later, when I got to high school, the girls in the secretarial-track training got taught how to actually program the things (I think; they definitely learned keypunch typing and drum programming, but I think they also got to do the wires.)

I have to admit, that actually *is* sorta cool. Imagine, you can probably repair a bit on that computer with a well-bent paperclip. When everything goes down the drain, this thing will still be up and running, maintainable and you will be able to build your own spare parts for it using a regular toolbox and a soldering iron.
Then again, my very first computer, a PC 1402 Sharp Pocket Computer from 1986 with cashstrip printer is probably like a bazillion times faster and more powerfull than that thing. It would probalby take less than two weeks to replace the entire workflow with a single cheap-ass current programmable calculator and you could add some features along the way. That makes it quite strange too. Cool, but very strange.
My 2 cents.

a) I am a literal product of IBM. My parents met while working for Big Blue in the late 60's.
b) I emailed my father with this link, and here is his reply:
"Actually, I really did know how to wire ("program") the 402. And I probably still could if necessary. It was so easy, but a little complicated. If you made an error, you just re-ran the deck of cards.
A little known fact was that you could make it run faster if you used a rubber band in a special pulley location.
"
That's standard Electronic Accounting Machinery and punch cards.. "Tab cards" if you need to order them..
15 years ago, you could still buy standard 80 column cards by the case (couldn't buy a box of 2000, had to buy 5 boxes), and I suspect someone still makes them and sells them. There's a lot of old S/360 machines around of one sort or another.
And, I think that's an 029 keypunch (based on the switches above the keyboard), which *was* state of the art in the early 70s, as opposed to the earlier 026. A quick check shows that the 029 was introduced in the mid-60s along with S/360. I used to have to use multipunch in 1973 to get 029 codes for parenthesis and such in FORTRAN programs when using a 026 punch, which is what my HS had. (some motor memory things you never forget.. The last time I used a keypunch was at UCLA in 1979, and I wound up sitting in front of one in around 1997 needing to punch some cards. Reached under to turn on the power, hit the toggle switch above the keyboard for the feed to get the first card in, and blasted away like I had never stopped using it. Truly an odd feeling.)
see, for instance, http://www.youtube.com/watch?v=iXLfiAvkbyg that's a 129
http://www.youtube.com/watch?v=QSNox5iqNmU is an 029

That's when I was there! Maybe we ran into each other back then.
Sure, we used punch cards for the two Fortran-for-engineers classes I took in '66-67. We coded Fortran IV and Fast Fortran using "official Fortran coding forms."
It works when the requirements are set high for some artificial reason, for instance to reduce numbers of applicants to a popular course or school, and the actual background required to do the course is less than demanded. Of course that creates a lot of ill felling where some people that couldn't get in via general entry are allowed in, but if you have a limited number of places and want the next generation of doctors or whatever to be spread all over the country instead of just in the affluent parts of major cities then admission has to be a bit more complex than just the few with the highest test scores. Sucks for those that miss out but better overall.
In a small company like that? The head accountant who was there for forty years could certainly make the call to upgrade the system if she wanted to. At the most she might need the OK of the boss that she is on a first name basis with. But simply saying to the boss, "we really need to update this ancient equipment, it will save up a lot of money in just a few years" should be enough. No, the only thing that makes much sense is someone standing in the way of the logical choice. And if it is the boss he isn't being well advised.
I'm an American. I love this country and the freedoms that we used to have.
Yup... CDC 6600 assembler made no sense at all until you realized or were told that the 6600 was designed to run FORTRAN fast. Then the light was blinding.
One of my first engineering jobs was programming an old milling machine. You wrote the program code in an editor on a computer, then had it output on a roll of punched paper tape. The code was punched into the tape transversely, in simple 8-bit ASCII. Hanging chads would really ruin your day.
My big contribution was a program that could punch a human readable header onto the tape. Written in the finest QBASIC.

In the mid 70's Josten's, of school ring and caps/gowns fame used a Honeywell Octal Tape Operating System Mainframe for Payroll, and an IBM 360 - 40 with 64k core for all other DP. They also had a 360-30 to create punched tape to control the machines that made the rings. Honeywell SSEC used a Fairchild with cards full of reed relays for substrate (wafer) measurements in the mid 70's, and to 'fix' it we would open the card drawers and fan the cards, USUALLY unsticking a stuck relay. As late as 2000, Ryobi was using a DEC mainframe for engineering MRP/ ERP. Then there were the old UNIX boxes and the 1200 BAUD modems (an upgrade) with audio coupling - lol
With equipment like that, you're going to need an old grey-bearded mechanic on-site daily to keep things running. I supported a microfilm lab a really long time ago that processed aperture cards for distribution. They had a room full of antique IBM "unit record" machines and an old support engineer overhauling one machine or another every day. And that stuff was fossilized back in the 70's.
