It's probably 1134A F.M. print set #MP00190? In it you'll see on sheet 3
of 3 on the Unit Assembly dwg E-UA-1134A-0-0 the illustrations regarding
the cabling between the KY11-LB and the M7859. The key indicators are
marked. I placed a Post-it note right on that page reminding me of that
swap as I usually forget little details like that over a period of time.

I don't think so. Many folks seem to like the nuts 'n' bolts of hardware
discussion from what I've seen over time here. We're doing a bit of
documenting of getting our systems up which is important for the archives.
Besides, the folks interested in listening-in are probably watching (and
may contribute to the discussion) and the folks not interested are skipping
it (based upon reading the Subject line)

I have neither. Sorry. BTW, fill me in briefly on what an LPS is.

One of the things that would help me a lot is the KD11-EA Maintenance
Manual #EK-KD11EA-MM-001. I suspect my problem is more complicated so any
way to better navigate the CPU hardware details will be of great help.

Also, the PDP-11/34 System User's Manual I have lacks specifics on the
/34A. Although mention is made of the 'A' it seems the manual
(EK-11034-UG-001, copyrighted 1977) was written before the /34A was
released. No mention in it of the M9312 (which has a diagnostic ROM
aboard). Just a bunch on the M9301. Anybody know if the diagnostic ROMs on
the 9301 and 9312 are the same? The 9312 diagnostic ROM part # is 23-248F1.
I have M9312 technical manual but *it* doesn't know about the 11/34A, just
the /34. Go figure.
