@@ComputerHistoryArchivesProject Thank you. Your shows make me appreciate microcomputer technology much more, even in this 2024 year, as I type. I would not want to look back to using the typewriter or anyone else's computer. You are welcome, and thank you for typing to me. Happy Keyboarding!
The book shown at 11:38, "Planning a Computer System: Project Stretch"- Our high school library had a copy of that book (c 1971). I remember looking at it when I was an eager young computing neophyte and not really getting anything out of it.
I worked for IBM in 1966 as a summer student at the Kingston Research Facility, and we were already working on what would become the IBM370 system later. Our project was a "workstation" for an auto company, for the designing of chassis frames for vehicles. That had a "light pen" which could interrogate a CRT screen image, make data point on it, and make corrections or additions to the mechanical design. It used Vector Graphics. You could "rotate" the chassis (in small steps) to actually look at it from various angles. This was way before the age of Robotics, but that workstation could have been used today, for welder positioning, painting, machining, or similar. The main problem was that it only had 1024-bits of granularity on the CRT (both axes). As a result, it would only be as good as a human welder. I got a job later, at much better pay, with a defense company, but I have always wondered why IBM did not jump into that workstation business. Later companies made billions doing so.

If you make a grid of 3mm holes about 100x50. Fill the holes with flashing LEDs. When powered up the difference in the LED timing will, after about a minute, give you a blinking light panel that looks just like real work is being done. Give it some plausible sudotech label and put it on the front of a server rack. Amaze your friends.
Lots of potential uses for blinking lights with a modern machine. You could assign them all sorts of meanings. CPU usage graphs, individual drive usages, temperature readouts, your imagination is the limit.

I just got my new Stretch Computer delivered by FedEx last week. In no time I've got it all set-up. This system is a lifesaver. Thank you IBM! But really, when I started watching this, I thought IBM named the computer "Stretch" because of all those stacked cabinets stretched out behind the operator's console.
is yours working properly?..mine keeps turning on all the blinky lights at the same time (or in the pattern of a sad face) until i reset the power (after calling the local power station) which takes about an hour..by the way when i first got mine installed ..i forgot to call the local power station so they could bring a new nuclear reactor online and when i powered it on the entire city went dark...just a tip for others installing their new Stretch Computer at home ...i have not received my first power bill yet i am sure it will be fine...
@@MickeyMousePark No rolling blackouts yet since I turned on my new Stretch Computer. My first power bill also hasn't arrived, but I'm not worried. All the heat it generates I can sell to warm the entire neighborhood come this winter. I think mine works. I asked it to give me the square root of 9. After some churning and all those Christmas lights flashing in front, it gave me the answer of 3. Incredible. IBM is no Mickey Mouse operation. If your power bill is high, run an extension cord into the Disneyland main power grid, and you should be good to go. :)
Follow up comment. My wife's best friend got her first job, out of college, as an IBM engineer in Chicago. Her first job was to produce a "light blinking program" for the Chicago Sewer System Control Station" where they allowed the "tourists" to wander in a gallery, and observe the working of the sewer system. The frontal board of the IBM370 showed the ALU registers, stacks, and other functions, but in actual operation the lights were just a blurred slow-glow, since the machine was so fast. As a result, she wrote a program, which visually looked like the machine actually did "something" as interpreted by human slow-brained observers. I won't mention her name, but that girl should have been working for Pixar, if Pixar had existed then. She was good, and had the concept. Not DEI in those days. We all had to learn Sexadecimal, which IBM renamed Hexadecimal in all of their manuals, for social purposes. I still can do Hex in my head, since I worked it for so long, kinda like riding a bicycle.
When anyone ever mentions Allied Master-computer, this is the type of computer I imaging him based on. Organized wearhouses of these linked together combined with a mix of older and newer computer equipment connected. Some organized as they were added before AM gained consciousness, others piled on in a disorderly fashion by AM himself, and even more newer computers created by AM connected.

Is this 1960 film one of the first moments where the term "mainframe" is introduced? At 7 minutes into the video different "frames" are shown and at 8.29 he mentions that the Exchange carries the information form the "main frame" and the rest is history.
Hi @gerteldering, that is a very good observation. Could possibly be. They started using the term in the mid 1950's, which is when the machine was being conceptually designed. Good catch! ~
I was under the impression until recently that the IBM System/360 was the first computer to break out of the “octal closet” of bits grouped by threes (as in 36 bit words and 6bit text characters) and group bits by powers of 2, with 8 bit characters called “bytes” and 4 bit “hex” (hexadecimal) digits called “bubbles.” But someone told me that the 7030 Stretch had such an architecture before the 360. Having had no knowledge of the Stretch before, I searched and confirmed that it did indeed have multiples of 4 bits expressed as hex digits! Since then, all but a few IBM computers and all personal computers have used hex with 4, 8, 16, 32, and 64 bit processors.
Yet as we make things smaller, they are actually getting bigger. To accomplish what we do today we have gigantic data centers filled with small individual components that dwarf these large computers from the 60's.
It's kinda weird to consider that your smartphone, which even though it isn't as powerful as recently assembled gaming computers, is like hundreds thousands times more powerful than that IBM supercomputer (especially with several clusters of superscalar out-of-order shaders in recent GPUs which are a bit hard to stall even with graphics and OpenCL code spaghetti, so they're also commonly used for supercomputing task even in your own computer at home which is crazy considering you can buy $10+ millions computer hardware for $300 to 2,000 a chip on the video card). Technological advancement is crazy. Still, I appreciate having digitalized films available on TH-cam - history is worth preserving and shown.
the stretch was 40 kIPS. Your basic modern appliance uses a processor in the low MIPS range, and yet no one uses their dishwasher to run spreadsheets. Essentially we have an incredible amount of processing power in our homes nowadays, and most of it isn't utilized.
Those cards look remarkably like the PCBs I recall seeing in electronics shops in my youth (Smiths of Lisle St in Soho for example) Of course they were minus their gold plated contacts.
One example was sold to the French atomic research agency and is partially preserved in the Paris museum of Arts et Métiers. They have the control panel on display and some of the drum broken down so you can see all the heads and wiring. Probably the only example this side of the pond.
Interesting that it had both an Operator's and Engineer's consoles. My guess is the operator's console was used to run the computer, and the Engineer's was to keep the computer running! I saw enormous vertical hard disks like that in an old movie recently. Wish I could remember which one; I didn't think they were real!
Hi @gdavisloopfta380, yes, quite amazing to see two such large consoles on one computer! Quite massive and needed full time oversight. The vertical hard disk (RAMAC unit) were used connected to many other IBM big computers of the late 1950s.... Thanks very much for the feedback!
Hi @johnsavard7583, yes, very true. It seems the designers were way ahead of their competition at that time. Some pretty advanced concepts made it into the machine, and into future machines. ~ Some smart folks there.
Good question! Here is some info that might help: The system was probably air cooled. The 169,000 transistors required a total of 21.6 KW of power (21,600 KW). Several references stated that the whole system was over 100 KW at 110 volts, but that number depends on which auxiliary modules are included in the total. The system probably used aluminum racks as well. Overall, it would generate considerable heat, but much, much less than the earlier vacuum tube based machines. The large 7090, 7094 machines used cooled air under the raised floor. Extensive prep of the facility would be needed before installing the 7030 STRETCH, to ensure adequate air flow and power management for A/C units, plural. (As more info is obtained on this question, we will post it here as well. Thanks very much.)
@@ComputerHistoryArchivesProject O worked at a data gathering company in Phoenix that went from a mom and pop operation (and didn't spend the money to keep things up and running) and used "people A/C units" in the computer center. They got bought out by a larger company and decided to upgrade with the latest and greatest servers. During the planning sessions the sales rep told my bosses how much A/C would be required and how much power usage would be. I was looking at the spec sheets and called him out on his "estimate". I got ripped by the bosses and told to not disrespect the sales rep as this was his job. So, I ordered what he recommended and it arrived and I got the systems installed and had our electrical contractor add the requested panels installed. He didn't even get 1/4 of the servers plugged in and I "lost" the room due to heat load and got called in to get ragged on AGAIN. I pulled the meeting minutes and showed them where THEY over rode me and told me to go with what the sales rep said was needed. I ended up having to order 4 MORE Liebert's and additional electrical panels from the main switch gear room. A couple of heads rolled on that one and I was vindicated. Moral of the story LISTEN TO YOUR A/C. He does this for a living.
@@captainkeyboard1007 As I found out, sales reps will say ANYTHING to get a sale. He majorly DOWNSIZED the amount of heat that would be generated as well as the power consumption.

Man, I so want the little computer set at the 2:30 and 3:20 mark... My 7950x Snow White can crush Stretch and is about the size of that model stacked together... but like... 40 years later so... shrug, not a win ;-)
I read somewhere the Stretch was nicknamed "Twang!" because it pushed the technology too far. Many of the features were later "cleaned up" and used in the 360. Lytton Strachey described it: "I get the impression that Stretch is in some way the end of one line of development. Like some early computer programs, it is immensely ingenious, immensely complicated, and extremely effective. But somehow at the same time crude, wasteful and inelegant. And one feels there must be a better way of doing things."
The performance difference is quite dramatic. The $3 ESP8266 can do about 75 VAX MIPS non-floating point. The IBM 7090 metioned as being a little slower than IBM Stretch could do about 0.186 MIPS scientific calculations. The ESP8266 would have to do floating point in software but even so it would probably be way faster than the IBM Stretch.
You might try the Computer History Museum in Mountain View CA. I think they have portions of the original Stretch IBM 7030 machine. Because of the size and age, it is doubtful anyone has a full working system, but the parts are quite impressive themselves. ~ CHAP
That is a great question. Don't have the answer at the moment, but that is one for further research. My guess is that if they found a bad card on a machine used for high-accuracy atomic research calculations, they might want to stop and replace the card before doing more calculations. Just a thought. Perhaps someone in this thread will know the answer to your question about hot swapable SMS....
... ALL those people Were Engineers... you needed a Mathematics, or Science or an Engineering degree to work on systems like that. There weren't any ITT Techs, or DeVry, or Kaplan Institute graduates there, or from any of the other #Fake Trade schools like Corinthian Colleges (Everest, Heald, and WyoTech) 🤔 Those people got better jobs.
Very interesting. Does CHAP do the narration on these videos? How long was STRETCH the world's fastest? Some of the later systems mentioned were still around when I started. A school where I worked had an ex-NASA IBM 360/91 which had once been one of the world's fastest. Had a feeling of real power at my fingertips when running jobs on it.
Hi @dalecomer5951, Thanks very much for your feedback. We research and draft and produce narration when there is no narration to the film. Many early clips from the 1950's are silent, or have simply lost the audio portion over time. ~ STRETCH was top dog in speed from 1961 until 1964 when the CDC 6600 came out. Lawrence Livermore acquired a 6600 for $8 million in August 1964, and that was fastest until the faster CDC 7600 came out in 1969. It was a mad race for speed... Government funding kept the computer firms pumping out faster and faster machines. ~ Your work at NASA sounds like a great experience! the 360/91 was a powerhouse from what little I know of it. Sounds like fun!
@@ComputerHistoryArchivesProject Hi-- I worked for a school (State U.) which got the 360/91 surplus from NASA after Project Apollo. There were a number made available. I should find out what replaced those at NASA.

Like some early computer programs, it is immensely ingenious, immensely complicated, and extremely effective. But somehow at the same time crude, wasteful and inelegant. And one feels there must be a better way of doing things."
Hi @JedRothwell, good points! Thanks for the thoughtful feedback! ~ VK
good vid just think now you mobile phone has more power than that computer :) but still enjoy seeing that old tech :)
The machines built today's machines. Computers can out think every human on the planet.
It appears this computer used 64-bit words, so the 2 million word hard disks would store 16MB each - which is larger than my first hard disk!
And today the whole hall is lying on my desk as a matchbox-sized ESP8266...
The performance difference is quite dramatic. The $3 ESP8266 can do about 75 VAX MIPS non-floating point. The IBM 7090 metioned as being a little slower than IBM Stretch could do about 0.186 MIPS scientific calculations. The ESP8266 would have to do floating point in software but even so it would probably be way faster than the IBM Stretch.
Is anything like this still around and working, for demonstration purposes???
You might try the Computer History Museum in Mountain View CA. I think they have portions of the original Stretch IBM 7030 machine. Because of the size and age, it is doubtful anyone has a full working system, but the parts are quite impressive themselves. ~ CHAP
At 6:49 he says "more than one billion operations per second". It should probably be million - or maybe I'm just hearing it wrong...
Sounds like "billion" to me, too.
You are probably correct!
4:50 were the SMS Cards Hot Swapble, or did they have to power down the machine before hand?
That is a great question. Don't have the answer at the moment, but that is one for further research. My guess is that if they found a bad card on a machine used for high-accuracy atomic research calculations, they might want to stop and replace the card before doing more calculations. Just a thought. Perhaps someone in this thread will know the answer to your question about hot swapable SMS....
Yes. On, for instance, a 7094 system, the power down/up process was relatively slow, so we would hot-swap.
Must have been horrifying to that generation to see their jobs replaced by such leaps in computing.
Eventually the leaps in computing created a massive number of jobs.
I owe my career to the massive leaps in computing that followed in the 80s and beyond.
... ALL those people Were Engineers... you needed a Mathematics, or Science or an Engineering degree to work on systems like that. There weren't any ITT Techs, or DeVry, or Kaplan Institute graduates there, or from any of the other #Fake Trade schools like Corinthian Colleges (Everest, Heald, and WyoTech)
🤔
Those people got better jobs.
Very interesting. Does CHAP do the narration on these videos? How long was STRETCH the world's fastest? Some of the later systems mentioned were still around when I started. A school where I worked had an ex-NASA IBM 360/91 which had once been one of the world's fastest. Had a feeling of real power at my fingertips when running jobs on it.
Hi @dalecomer5951, Thanks very much for your feedback. We research and draft and produce narration when there is no narration to the film. Many early clips from the 1950's are silent, or have simply lost the audio portion over time. ~ STRETCH was top dog in speed from 1961 until 1964 when the CDC 6600 came out. Lawrence Livermore acquired a 6600 for $8 million in August 1964, and that was fastest until the faster CDC 7600 came out in 1969. It was a mad race for speed... Government funding kept the computer firms pumping out faster and faster machines. ~ Your work at NASA sounds like a great experience! the 360/91 was a powerhouse from what little I know of it. Sounds like fun!
@@ComputerHistoryArchivesProject Hi-- I worked for a school (State U.) which got the 360/91 surplus from NASA after Project Apollo. There were a number made available. I should find out what replaced those at NASA.
Air-conditioning has left the chat 😅 Seriosly I wonder what, transformer based, PSU they had and what waste heat those data centers had produced?
6 x 32 words = 192 kB
I.e., less than my Google TV remote control.
Was this the first look-ahead unit? You'd think Intel invented it in the 90s if you believe the marketing...
Kouini transistors
Is that a specific type?
IBM
Yes it is.
One Mega-FLOP! Such speed!
Thank you!
