Well, I pulled the E2 op-amp and replaced it with a NOS one of the same
model. Put the supply together and now I am getting -17 volts on pins E2
to ground (E10).
I'm thinking of just replacing the power transistor Q12 with a 7912 -12v
regulator that I have here and bypassing the whole op

The link below is a screenshot from the onboard KDJ11-B 'print a memory map'
function. It confirms the DEC MSV11-R is recognized as parity.

I don't know what that is, but it's not an MSV11-R. Here:
https://gunkies.org/wiki/File:MSV11-R.jpg
is an MSV11-R.

I can confirm that the DEC MSV11-R is a PMI card. I own two and have used them
with my KDJ11-B.
The vcfed.org thread linked by someone else was actually started by me when I
purchased them and couldn't find dipswitch
One is a DEC M7458 MSV11-R, the other is from a 3rd party "General Robotics
Corp." according to the printing on the board, which apparently happens to
share the same model name.

Would love to see it, I have such a machine in the queue for restoration.

Cool, but can't see without logging in. Was the other pic wrong?

Ok. I think this is a picture of it:
http://www.aceware.com.au/acms/images/Invent/GeneralRoboticsMSV_11R.jpg
However if it is PMI then it does not have ECC. That's more like a
MSV11-Q type memory.

The link doesn't work but this does.

Maybe it's PMI memory without ECC? I count 18 bits across which seems
like the MSV11-Q parity memory.
Does it say PMI on the side?

That must have been quite a machine to beat a person five times in Tic Tac

Yes, the Monrobot is particularly interesting
because (among other things) it was reviewed
in the New Yorker magazine.

So, I've come across an odd book that might interest some here: "Achieving
Accuray: A Legacy of Computers and Missiles", by Marshall William McMurray.
The first couple of chapters merely re-tell the story of earliest computers
(pre-elecronic and electronic), up through the IBM 701, Elliott 401,
Hey, all.
I was browsing various craigslist places around the US and found someone
selling off a substantial collection of classic micros outside Minneapolis
