- Computer History: IBM ANNOUNCES SYSTEM/370 MAINFRAME COMPUTER, The original 1970 Announcement Film! Introduction of the IBM SYSTEM/370 family of mainframe computers (in 1970) was a pivotal moment in computing history. This original IBM film describes the origins of the 370 and some of its capabilities and advancements over its predecessor, the IBM 360. This full color, partially restored original 370 announcement film describes the thought processes that went into the development of the new IBM SYSTEM/370 advanced architecture. The 370 became IBM's most widely used platform not only for decades. The film is provided for educational and historical purposes and runs about 10 minutes, followed by an Appendix of photos, supporting material and references. Your comments and experiences with the IBM SYSTEM/370 are most welcome!
We hope you enjoy this brief taste of the world of computing, as it was, just a few decades past. Uploaded by Computer History Archives Project (CHAP)

During my IT career spanning 46 years as an operator and as a systems programmer I worked with 360/40, 370/125, 135, 145, 155, 308X, 4381, 4341, 4331, 309X, ES/9000, 9672, z/196 and z9-13.
Hi @knightwatchman, Wow, that is an impressive list of equipment!! Very good experience spanning many years. Thank you for sharing that! ~ VK, CHAP
@@ComputerHistoryArchivesProject Thanks! I forgot to mention 370/138 and 148. Back in those days it seemed we had to upgrade every two to three years.
I repaired all of them being an IBM CE......some more 370/158 with AP- Attached Processor -, 3031 & 3033.
@@Jose_Altuve_ I was a mainframe customer for 14 years then an IBM SE for 32. Retired 2019. Loved you (CE) guys. Oh man, 303X's. What beasts they were. I had a 3031 down for 18 hours once. Took 16 hours to find the problem and two hours to fix it. CE(s) reported it was a tri-lead failure. Man ... they had oscilloscopes all over that machine trying to find the problem.
Thanks for this. When I started my programming career in the 70s, the company had just replaced their S/360 65s with S/370 168s. I worked on many 370 architecture machines until the early 2000s, including 370, 43xx, 93xx, 30xx, and a few compatibles such as Amdahl, and ITEL (I think)
Hi @Stuart-AJC, thanks very much for your input on this and your experience with various 370 and other machines! It sounds like you have some great experience. From the 360 to the 30xx machines covers a lot of ground! That's a broad time frame of technologies! Do you have a favorite system? ~ Victor
@@ComputerHistoryArchivesProject I think the more obscure ones. The 9375, which was a S/370 in an AS/400 type chassis was an unusual one I worked on in Africa.
And the last one I worked on which was the P/370, basically a S/370 on a single card in an RS/6000. The RS/6000 ran AIX, and the P/370 ran VM & CMS
Hi @Stuart-AJC, those are some interesting computer models. The P/370 especially was a unique machine from what I have read. It has a unique place in IBM's toolbox of computer systems. Thank you very much for sharing your info and memories on these machines. Great history! ~ VK
WOW, 3MB of storage!? Who would ever need that much storage?
😂👍
Don't worry, nobody with one of those newfangled home computers is ever going to need more than 640K of RAM, so 3Mb of storage will see you fine forever!😅
Used more for speed of calculating than storing information. Memories and such were created as the need would dictate.
my kingston pendrive is 1TB 😀
One shop I worked in had two model 168 machines. They bumped main memory up to 6 MB!
It's nice to see @ 10:40 the dashboard saying "ACME is on".
"With 100% monolithic circuitry. The performance computers for the seventies."
Ironic that the blue color has faded out of this IBM film
Yes, that would be ironic.
At 9:55 is one of my favorite devices: the 2305. That unit kept the fixed heads at a temperature of (I think) about 10C, a large amount of space under the window was the cooling system. There was a small box in the back that would cool cans of quite quickly. a meter deep, 2m wide, 1.5 m high. Could handle 4 channels coming into it, the 2ms response time was because of multiple heads on each track. Lots of power draw. Maximum storage capacity: 16 MBytes! (The 3330's they showed could go up to 220M per pack.)
Hi @ericlburch, thank you very much for sharing your memories of the 2305 device! Sounds like you are very familiar with its workings and uses. Good memories! Appreciate your feedback! ~ Victor, CHAP
Reassuring really on to see "chaps with pipes" drafting the future. Those were the days...
Hi @connclissmann6514, Yes, definitely, the pipes made them more intelligent... or at least looking more intelligent. : )
Wow, as little as 2.5ms access time on a fixed disk. Amazing speeds!
Yes, pretty fast for those days too!
@@gmc9753 Now available with an SSD interface ... or maybe not? 😊
These early machines did not have virtual storage as I recall. The model 167 did if I recall correctly.
The white shirts are on the way 😂
Due to memory limits, programmers were really cleaver on how they utilized memory. With gigabytes of RAM available so inexpensively, programs have become bloated.
Thanks CHAP for the look back.
Two million bytes? Wow! And Bill Gates told us once, nobody needs more than 640kB in his computer.
Great video!
Glad you enjoyed it. Hope you will explore some of our other vintage tech and computer videos too.
3:08 Now that's some good old -fashioned IBM multi-tasking there! Put that in your pipe and smoke it son.
The real innovation the 370 line brought out was virtual memory. The 145 was the first box that had the DAT (data address translation) hardware but that was not anounced until some months after the first box was delivered, The 165 and 155 did not have this hardware. We lucked out as we bought a 145 and ran MFT on it, We were able to migrate to VS1 without any additional hardware!
Hi @haroldz9915, yes, great point. The virtual memory was quite an upgrade in this family of computers. It added a new aspect to large scale computing. Thank you for your thoughtful feedback! ~ VK, CHAP
DAT is actually "Dynamic" Address Translation. It's the process of translating a virtual address during a storage reference (which makes it "dynamic") into its corresponding real address. The 155 did have a DAT, but it was an optional feature. We called it a "DAT BOX". The CE would show up with a box and plug it into the 155. That upgrade made the 155 a 370/155 II aka 155-2. I loved working with this machine. It "talked" to you constantly with all those flashing lights and that buzzing 3215 operator console.
@@knightwatchman correct, faulty memory
@ Mine isn't so great anymore either, but when it comes to that 155 its still pretty vivid.
The 165 could be upgraded to a 165 Mod 2 that added a DAT to provide virtual memory. You could then run MVS 3.8 (OS/V2). Our shop had a 165 Mod 2 but it was an expensive upgrade for the 165 and not a lot of shops had this upgrade. We also had an Amdahl 470/V6, which was roughly equal to a bit more than the power of an IBM 370/168
この時代はコンピュータの設計は製図だったんですね。プログラムの設計も手書きだったし、プログラミングも紙に書いたのを打ち込んで貰って自分で直接プログラムを打ち込まなかった時代だし。今からすると、コンピュータの設計にコンピュータ使わないのか？と驚きですよね。
Thank god we have computers now that can design systems, i would hate it to draw everything by hand
(Google Translate says: "In this era, computer design was done through drafting. This was a time when programs were designed by hand, and programming was written on paper and then someone typed it in for me, so I didn't have to type in the program myself. From now on, why don't we use computers to design computers? That's surprising, isn't it?" ) --Hi @800neko, -- Thank you for the thoughtful insight! VK
@ The google translate is incorrect. It translates more to something like:
"Back in those days, computer design was done through drafting. Program design was also handwritten, and programming involved writing code on paper and having someone else input it-you didn’t enter the program directly yourself. Looking back now, it’s surprising to think that computers weren’t even used for designing computers!"
The fact that the Japenese commenter is reflecting on the fact that the first computers were designed without a computer is lost in Google's translater
@@kaasbaas9532 Thank you for the accurate translation.
Hi 😊
❤😊
Ibm یه اسطوره است
Glad you enjoyed it! Thank you.
Nice 3D model of a 370/3033 ruclips.net/video/jZVkqASp1Kk/видео.html
Very nice 3d modeling. Thank you!
Amazing video. Thank you so much!!!! Loved seeing an African American in there! 😊
