I hope this qualifies as classic computing...
Does anyone have the pin-out for the P2 connector on MVME processor boards?
I think that the pin-out would be the same for MVME147, MVME177, MVME162,
etc. and would mate with the P2 adapter board.
I have a x/280 server chassis that has a power supply that's acting up (DC shuts down
after a few seconds)
Anyone have one they can spare? Sun PN 300-1024

or has anyone seen this problem before (caps in the DC monitor circuit?)

A couple of observations on the following code:
1/ It is written for, and uses TOPS20 syscalls. If you intend to run this
under TOPS10 change the syscalls (LITES% and DISMS%) to the equvialent
TOPS10 counterparts, can be done by including these lines:
SEARCH UUOSYM
OPDEF LITES% [LIGHTS]
OPDEF DISMS% [HIBER]
2/ The program uses the CIRC instruction, which is not present in stock
DEC processors, and possibly not known to MACRO-10. You could try
OPDEF CIRC [247000,,0]
if that is indeed the problem.

I have none prior experience with Multics, so it is going to be
interesting. I guess.

I couple years ago I completed the design for my USB Panda Display[1]
board. This is a modernization of the original Panda Display once
distributed by Spare Time Gizmos[2]. Both devices are intended to be
connected to a more-or-less modern x86-class computer running the klh-10
pdp10 emulator and provide useful blinkenlights. The development of klh10
is once again active, this time on Github[3]. I created my own repo of
klh10 as a means of writing support for my new Panda Display. The
display seems to be recognized and used, but what it displays is
meaningless. I cannot fully test it until I can get the old test program
compiled and working. Once that's done, I'll add my changes to the
PDP-10/klh10 repo and delete my own.
Here's a video of a computer with the old Panda Display running klh10:
https://www.youtube.com/watch?v=g_LcQ5apODg. The creator of that video,
Jan de Rie, got the program that was used to generate that pattern from
Mark Crispin, the creator of the Panda distribution of klh10. That
program appears at the end of this post.
I'm looking for someone who knows TOPS10 / TOPS20 well enough to figure
out for me why this test program won't compile. Once that's done, I can
complete the firmware for the USB Panda Display an its support within
klh10. I'll then make more copies of the USB Panda Display board (and
maybe overlays) for whoever wants them.

Yea, we tend to use couriers but it runs to a few hundred dollars a pop.
I will send pics off-list sometime next week.

Yes, it is identical. I was the original beta tester on the
SCDC and used it extensively. In fact, the designers called
it "the Frisbie port". :-)

You may need a null modem. Try swapping pins 2 and 3.
I can send you an genuine Andromeda DB25 adapter if you give
me a mailing address and promise to send me $10. :-)

They changed between the original Rev. A and final Rev. F
boards. Which one do you have?
I can send you a copy of the manual, complete with all my
editorial comments written on it.

I see some company selling them on eBay for $122.? Are they really worth
anything like that?? I have a couple sitting around here somewhere that I
don't expect to ever use again.? Just wondering if they are worth looking
for to sell.? In this hobby you can always use money for new (well, old
actually)
toys.
