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.

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?

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.
