big announcement for Friday: I have acquired a datacenter that has not been touched since approximately 2002, and is FULL of old 80s/90s/2000s IBM mainframe equipment.

@wec You gotta be kidding! Spill it, is it a ES/9000? jaw: dropped!!!
buncha S/390 G3s, G5s, and original Zs. craploads of 3270 and 3174 too lol (also two 3745s and two 3172s)

@wec 3745!!! i am so excited!!!

@wec I'm starting to think 80s computer hardware is our generation's answer to "basement full of model trains"
@WizardOfDocs @wec "But you can actually do shit with vintage computers!"
Do you do anything with those computers once you restore them?
"...no, but I--"

@WizardOfDocs @wec What about 90s computer hardware?
-
@wec @WizardOfDocs Glad to see there continues to be exceptions to the rule

the next outrageous project is going to be to migrate my mastodon to one running on a VAX 4000… far slower than an S/390 G3 (which clocks faster than an Alpha 21264, which ran my previous mastodon)

@wec OMG the first programming I ever did was on a 370 and all that JCL!
-
@wec You need to acquire a Bond Villain chair and a fluffy white cat for your mainframe lair. Just saying.

@SamanthaJaneSmith @wec Way back in the depths of time one of the folks at Interactive Systems (the first commercial Unix company, circa 1980) wrote a JCL interpreter and job processor for us by those who wanted to treat Unix as a batch processing machine. We copied the job pages and other stuff from UCLA's data center. It was quite impressive - an entire JCL deck just to copy a file, including several pages of resulting printout.

Just bear in mind that you can't get spare parts or maintenance for 3745s any more. (The $Dayjob quartet (split over two datacentres for resilience) were finally shut down after this moose retired; when the last remaining user "You can't shut us down, it's Safety Critical!" was advised of the running cost for their _eight_ sessions, and they would be charged for licenses, power, aircon & maintenance...) I spent 4 years trying to persuade them to switch to TCP/IP. 3:O#>

@karlauerbach @wec Oh yes! I can imagine although I don't know why anyone would want to do that. Although I do remember some really complex JCL for when the 370 acted as a front end for a Cray 1s... That was horrendous and generated a few forests of LP paper with stack overflow errors... I am going to have nightmares tonight!

@wec Wait, are you gonna outdo me on 3174s now? I thought I had cornered the market! (Had 20+ at one point, down to like 12)

@SamanthaJaneSmith @wec We did the JCL-on-Unix thing for the fun of it - and to show people who did not comprehend time sharing.
I got really good at JCL - I was doing satellite stuff and we had compilation jobs that could take 18 to 24 hours. So I rebuilt the JCL to optimize things and got it down to roughly 6 to 8 hours. Most people at that time did not realize that for sequential files - like compiler intermediary files - tape was much faster than disk. So I had umpteen tape drives spinning away. (Each run produced a mountain of printout - about eight feet high!!)
Another yuck-thing we did was to put the Unix swap onto a DecTape. Poor tape drive, but it did work.
BTW, out at the Livermore labs we used an old CDC 7600 and an obsolete Cray 1 to manage our tape library for the newer Crays. (I ported Unix onto those machines.)

@karlauerbach @wec I love the idea of doing it for fun! I am now nostalgic for tape drives and i hear you about the paper piles
Ah yes I remember putting a job to run in on a Monday and getting the results in a Friday. We did one run every two weeks. So it meant you really had to check the code thoroughly!
I also had the pleasure of using a CDC6700 and 7600 at the University of London computer centre. I really liked using them despite the large card decks due to the use of update and insert cards.
You said you worked in "satellite stuff" can I ask who for. I spent my whole career in the space industry hence the interest.

And I would be confident that none of that amazing hardware will ask you for your age or date of birth
