I had a trip down memory lane yesterday - I cleared a path to the filing
cabinet and got out my old IBM glossy leaflets. As well as things like
"IBM 3090 - the Base for Growth into the Nineties" I found a couple of
things on the 9370 series. I also found some stuff on PC graphics
platforms and 3270PCs (of which more in my next).

If you are interested in operating systems, those listed for the model
60 were:
VM/SP
VSE/SP
IX/370 (The AIX you were asking about)
MVS (which won't run on the 9373 (model 20) or model 40.)
There were also integrated packages carrying their own environment based
on VM, which was then called VM/IS
Just because the sticker says 30 amps does not mean it will draw that
much! In general, those ratings are worst case (a fully blown system), and
includes some safety factor (as well as some surge).
Oh I already knew that, William. A 30A breaker works out fine to handle the
six 9332 DASD units (IBM's accronym for these type of hard disks for some
of you other observers), 9345 tape drive, rack power controllers and the
9370-60 CPU. Can't recall exactly, but total draw was about 11
to 12 amps or so when I
Sounds about right. 11A at 230V is 2.5 kVA, which will do 1.8kW at 0.7 power
factor (typical for a rectified mains power supply) with ease.
Still dumped alotta heat! :-) We got cheap electricity in this town. $0.036
per KWH vs. about $0.08 or more per KWH outside of the area.
Even $0.08 is less than we pay (typically $0.11). But we can get dual
tariff systems which charge us the same peak rate and less than half
that off-peak for heating etc. But I digress.
Can't wait to work more with the system later this year if the wife has no
additional remodeling in the new house for me to do :-(
Have fun!

This sounds like a perfect time to get on my soapbox concerning big
computers and electricity!
Lets say you have this wonderful IBM mainframe and wish to use it. When
you add up all of the DASDs, maybe a terminal or two, perhaps you end up
with a 3 kW system. Now run that value thru your electric bill. I think
that you will find that a night of hacking on your system will cost less
than a ticket to a movie!
And I must admit that I am suprised that the CPU sucks so much. I suppose
if some of the memory was taken out, it would be quite a bit less. My
Sun-4/280 draws a hell of a bunch, but it has 32 megs of 41256 DRAMS,
each one sucking a little bit. Just removing 24 megs from it drops the
power consumption greatly.

Yep. Just the 9375-60 Processor Unit weighs-in at 290 pounds (132 Kilos) !
(My memory failed and I called it a 9370-60) The unit is about 27 or 28
inches tall, about 27" deep and fits in the 19" rack width. What a hogger
to move. Two large fans in the power supply move a bunch of air thru the P.
S. sections and circuit board rack. Only two or three additional circuit
boards added over the base model. 18 total, IIRC.
I just found within a paper archive on my desk (aka: a pile) that the 9370
was announced in October 1986: "Four models of new midrange S/370 CPU's.
0.5 to 2.5 MIPS." My company got this unit (likely the first one of the
production machines) in mid to late '87.
Have
fun!
Planning on it, Philip! I would be able to keep the list informed of my
progress with getting the system completely up and running if any interest.
This is especially true if list members help me out through the list. Could
be informative for a few others like I've been pleasantly informed. While
I was watching past threads in which list members helped get other folks
through startup questions/problems on DEC machines, etc., I learned a few
things which is rather satisfying.

Yes, I am interested in OS's for this iron. VSE/SP was running on it before
system shutdown in mid-'96. Don't know what version though. Gotta get past
that place where IPL stopped to see an opening screen.
I could not take the 3174-1R Communications controller and all 20 of the
3191 Display Stations. No space!!! Kept 2 3191's. I suspect the machine is
looking for the 3174, cannot find it and then halts during IPL with a
message that I cannot recall now. The Processor Console is actually an IBM
PS/2 model 30 (the bottom-of-the-PS/2-line 8086 machine). Hard disk is
possibly getting flaky and I need to find a replacement or simply try to
run the 9370 Processor Console software on a different PC. Microcode was
loaded into the 9375 from the Console machine's hard disk during IPL.
The _huge_ 3262 printer weighed over 500 pounds (227 kilos) so that was a
definite no-no to drag home :-(
I need any VSE/SP OS manuals that can support me! But I want to keep an
eye open for IX/370 and any documentation which I previously heard of being
available. Is it true what I heard that IX/370 runs on top of VM/SP??? If
true and I can find IX/370, then that would for sure mean I try to obtain
VM/SP and documentation for this machine too.
In addition, any other literature, brochures, advertising, etc. which are
related to the 9370 systems I would be interested in obtaining to help
further document them. Anybody have anything they're willing to part with
out there?
There were also integrated packages carrying their own environment based
on VM, which was then called VM/IS
