Well actually the "everyone will do it once" on/off switch was by your right knee (not left) and was on the series 33, 44, 48 and 58 which used the same box layout. Hi-tech fix of course was a piece of cardboard taped over the switch

Ah, the knee-power-switch on the 58. He had one 1988 - 94, as a downgrade from a 70 when the company hit some rocks and did some reorganizing.

Hi Folks,
Wow IBM 360 I guess I will need to show my age also. My third employer hired me in 1984 to help finish a stalled conversion from the IBM 360 to a HP series 58. At least I think it was a 58 low and looked like and oversized desk with a wood grain top. You know the one with the power switch under the desk on the left so you could hit it with your knee and shut the power off.
If I remember correctly our 360 had 64K of memory, 5 tape drives, 2 disk drives (a total of 7 meg I think), card reader, and a really large fast printer (I think 1200 lines a min). I wish I was smart enough at the time to take pictures. I am pretty sure it was one of the very few 360's still running at the time. I remember the IBM repair tech was also the IBM typewriter repair guy also.
So I worked on a HP series II in school, started my first job on Sperry Univac 90/30, then IBM 360, back to HP, and now teach programming/windows/Linux. Shoot I have been around the block a few times. I have been folded, spindled and mutilated. When do I get to retire?

Hey, Jeff and List:
Amazing the backgrounds of the last few posts- started on a 360/20 BPS (i.e.
card compiler, etc.), graduated to a 360/50 128k with 4 x 20mb drives, 3 tapes, etc. at university- started in Operations, went back to school, into programming, CDC6400, HP2000, NCR8200, HP3000 and a partridge in a pear tree. Memories indeed. Thanks for sharing, list...

The 360/30 had some optional firmware that did 1401 emulation. Not sure if it was available on the whole 360 line however...
Don't recall if ours at UTC had it or not... I never played with a 1401.
UTC had one prior to the 360, but AFAIK all the
360 code was
running natively by the time I got there.
By default the 360/30 only had 32K of RAM, and the supervisor would run 4-12K of that, depending on how it was configured. We had a third-party memory extension that ran that up to 64K (when I worked at a service bureau downtown, they were similarly configured; there was a third-party solid state 32K extension). Both were setup with a "spooler" you could run in a foreground partition to help with printing.
However, the stock IBM COBOL compiler on the beast required 54K to run.
If you wanted to compile COBOL, you had to reboot without the spooler / foreground partition active so you had 54K to work with :)
So the infamous MS-DOS / Bill Gates claims of "640K ought to be enough"
rang especially true back in those days, when you were clamoring to squeeze things into 64K. Geez, PC's had 10x the memory you had on the mainframe :)
I did systems programming for the service bureau eventually (after starting as an operator), and their Nashville office had a
360/40 with
128K of memory. Big time fun (at the time) :)
UT-Knoxville had a 360/65 with 512K (I think it was...) but it was running OS/MFT... never played with that, only DOS / EDOS on lower 360s.
