If you are not familiar with the systems at the time, this was a major leap forward in both user experience and productivity. For large IBM mainframes, development was still mostly punch card based using batch systems (both DOS/VS and OS/VS2). It could take a day to get a turn around for a compile. With VM, every programmer had their own computer, with an editor and file system to edit, store, and compile programs. It also allowed a single mainframe to run multiple copies of the DOS and/or MVS. If you want to try this system out for yourself, it is all in the public domain. Look up the Hercules emulator and the VM SixPack and MVS 3.8. You can relive the golden age of DP.

Yep, back in those days I was at University and was writing a lot of FORTRAN programs which would be run on an IBM mainframe. After creating my program I had to transcribe it manually onto punch cards. Then I had to submit my stacks of punch cards (some stacks were huge) in proper order and submit them to "operations". Sometime in the dead of night someone would take those punch cards, run them into a card reader, run the program. The next day I would find my stacks of cards alone with a print out of my program and the results. The average turn around was 12 to 24 hours from submitting the cards to finding the printout and results the next day.

She used the term 'abend' to mean the program crashed. That's proper old school!

Wow, mind=blown. Around 10 years after this, I interned/temped at the IBM Cambridge Scientific Center and at the time both Love Seawright and Dick MacKinnon worked there. Both were high-up execs then and we didn't see much of them day-to-day. Good old VM and CMS, I must have "IPL CMS"d about a bazillion times in my short time @IBM. By the mid-80s Rexx had gotten really popular so a lot of scripts were written in that language but there were plenty of EXEC scripts around still. We also had the internal VNET network with email, file transfer, mailing-lists (maybe forums too) - very "internet-like" long before the internet. Gotta figure out how to get "ABEND" into my coding vocabulary again, had completely forgotten the term.

Brings back memories. We used it as a way to provide a backup for smaller plant systems in case of extended outages. It was a dog, even on a one meg 168, but it did work as designed albeit more slowly. We never embraced CMS for development due to capacity limitations. Remember, in 1975 a meg of memory cost $50,000!

Now this is retrocomputing content. Showing computing professionals of the era (something archetypally nerdy about them) actually using the hardware and software to get something done. One thing not mentioned here because everybody interested in this video in 1975 would've known it anyway: the terminals were not like modern Unix terminals like xterm and so forth, which emulate DEC VT100 and above terminals, which presented themselves as just a grid of character cells on the end of a serial line. They had their own proprietary high-speed data connection, and a protocol that was closer to submitting web forms. Though you couldn't see them, there were fields in which you entered data which the terminal retained, and then when you hit enter the terminal would send the data entered as records back to the mainframe, which would then send commands back to update the display. So when Love is entering commands, there's a field at the bottom of the screen that accepts her command, and when she hits enter, only then does the command get sent to the mainframe. This allows for less interactive displays -- only Enter/Send and the F keys send interrupts to the program running on the mainframe -- but it was perfect for conserving the bandwidth and involving the CPU as little as possible, allowing the mainframe to support many, many more terminals than it otherwise could have. You can style your modern Linux, Mac, or even Windows terminal to look like the venerable 3270 with Ricardo Bánffy's TrueType 3270 font: github.com/rbanffy/3270font

This takes me back. I was a systems programmer specialising in VM/CMS, CMS and systems written in REXX. Later, I got to use Z/VM on our machine used for client recovery systems testing. I also could handle the other two operating systems, VSE and OS/VS, formerly MVS. CICS too.

The neatest thing I ever did was to get the University of Toronto's Operating system called Turing to boot on its own VM and run an interactive terminal that we then used to compile a C program and produce results on a virtual printer. and each of the six student teams was able to do that simultaneously. Back then we were pushing that mainframe pretty hard. I think the System Operator in the data center showed us our usage on the console as 95% of its memory and processor capacity when we all hit compile at the same time! It would be another 25 years before I could replicate that on a desktop with 4Gb or RAM and 16TB of hard drive under ProxMox.

Ah, the good old days! I remember the day when we cutover from punch cards to PC XT computers with 3270 emulator cards and text editor software. We could use any XT on campus, as we had a site license for the text editor software, who's name I forgot long ago, and input the JCL and COBOL or assembler, or FORTRAN IV program code for our programs and save to 5.25 floppy disks. We could go anywhere on campus that had an "program upload" XT and 3270 emulator card and text editor software linked to the IBM 4341 in the datacenter. All of the professors and accounting staff had the same "program upload" systems. If we had an XT, AT, or clone at home, we could purchase a copy of the text editor at the college bookstore and work on our programs at home. For me, this was a game changer and I didn't have to spend so much time on campus punching cards in our student punch card center, that was open 24/7, 365 days a year, except for holidays. We all cheered when IBM hauled away the old punch card machines. The datacenter still kept a reader/punch attached to the 4341 until all of the old campus programs were converted over from punch cards.

I had to learn that language (my second, after RPN) at the behest of my astrophysics instructor, who, with no regard to our "feelings", gave the class an assignment due at the end of the week which required using the mainframe (a Fourier analysis of binary star luminosity data), though not a single one of us knew Fortran, or had used the University computer yet. We walked over to the Computer Science Department, where I had a girlfriend, and found a kind soul who taught us Fortran in about 30 minutes. Do or die!

Yes. It would be nice to hear more about their lives. I wonder if their parents focused their education and careers on STEM fields. It would also be interesting if they have a similarly monotonous sounding voice as they describe their feelings. It would be interesting if it became a dominant genetic trait.

@@IARRCSim "I wonder if their parents focused their education and careers on STEM fields." The word STEM didn't exist, and their parents *certainly* didn't "focus their education" on anything. Hell, _NO ONE'S_ parents "focused their education" on anything beyond what they schools taught. The very notion is absurd. They graduated high school in the 1960s, so took typing and home economics classes, in addition to regular English, Math and Social Studies classes. Based on experience, I'd bet that the older woman started programming in college as a Math major, went to IBM and then moved to Training. The younger one was probably hired by the IBM training department, and she showed an aptitude for the technical side.

Amazing that in only 5 short years, MS-DOS-based PC's would be in households around the globe. Though not presented to the user's command-line shell, MS-DOS *was* capable supporting multi-tasking - just without any memory protection between the tasks.

More like 10 years. Before the Tandy machine in 1984 PCs were expensive office equipment rarely found in the home.

Wrote cms programs back in the 80's.

Look up the Z390 emulator (formerly PC 370) by Donald Higgins and the book Mainframe Assembler Programming by Bill Qualls (free online at his eponymous website). Use the excellent book in an undergrad computer science course and it is one of my favorite computer books of all time, up there in clarity and examples with K&R's C Programming Language and The Rust Programming language books. This video really is a look at the 'good old days' when promotional materials were filmed by actual people involved rather than paid talking heads. Really interesting, thanks for posting.

In 1989 I was employed in a company designing and engineering industrial systems using Unix machines, and one of the super geniuses involved told the newly employed me everyone knowing how to search in a Unix machine was an expert, and I was so impressed, shortly after a young guy was employed, and he was also this computer expert, only with PC's, he become a part of the Unix team, and one day he (accidentally?) disconnected the keyboard destroying the unix machine, after that he hated unix and used any opportunity to tell everyone

1980 is "first released", it was in internal use at IBM CSC in 1979. I know because I used it then & there as a summer intern. So it evolved sometime between '75 & '79, public release '80. (Other IBM CONFIDENTIAL packages I saw in '79 were still NDA & confidential in '82.)

I've written conservatively 30,000 lines of code in my life for all sorts of applications and data management tasks, and 10 minutes into this video I am 98% unclear on what the hell IBM Data Centers and VMs were doing in 1975 and whatever the hell they are doing here. The 70s and 80s tech industry predates me by a long time.

oh, the command «file» to file the file. Save sound a lot more dramatic, but im glad that confusion is gone nevertheless

Is this the sequel to Revenge of the Nerds? Seriously though, could someone please explain exactly what's going on here. Are the VM's on the mainframe and their terminals are the equivalent of thin clients or are the VM's on their computers and the mainframe is just for storing the data or am I completely wrong about everything?

I wonder how many German-speaking IBM COBOL developers must have chuckled at having an evening in their code.
