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.

BTW - it turns out I do have the 11/34a printset...
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'm much less of a guru than anybody as
I've never had my hands on *real*
PDP-11 hdwr until last summer/fall. I'm actually in the learning mode but
have done enough fiddling and have about half the resources I need to be
sort of maybe a little knowledgeable. (Is that vague enough?? :) That'll
be proved when I start working with the list for help on getting my own
11/34A system running.
Maybe my experiences, and the documentation of same, will help...
(I hope we're not putting everyone else to sleep with it) Let me know what tech mans and printsets you need.
Then I'll see what I
can do to copy missing ones for you if indeed I have them. However, I
lack several myself or have apparently too-early versions so may not
completly fill-in your needs.
As I mentioned, I have the 11/34a printset. I have not yet found
the VT11 printset, nor have I found an LPS printset...
Do you have these? (Does someone else have these?)
