M9312 Bootstrap Questions - test-drb@ccmp.vtda.org

24 Feb 2003

Well, my 11/34C has the M9312 in it.
See www.pdp-11.nl and click on the folder PDP-11/34A.
Inside that folder is a folder called CPU information,
in there is the folder options, and the last item is the
document "bootstrap" (M9312). Maybe that's a little help.
I have a scan of the M9312 manual and also of the M9301
manual wich will be at Jay's in a few weeks ...

- Henk.

 Jeffrey,

 are you sure the 11/34 manual is talking about the M9312? - I seem to 
 remember that my copy describes the M9301, of which, IIRC, there are 
 -YA, -YB, and -YF versions.

 Since all M9301s are completely different from the M9312, it 
 would be no 
 surprise if you cannot match the switches between docs and hardware...

  Ok, I got my PDP-11/34 mounted in its rack and
have started to audit
 jumpers, switches, etc. I am being cornfused by the M9312 bootstrap
 terminator module.

 First, I'm confused about what version of the module I   have. My 11/34
user's
  manual (EK-11034-UG-001 '77) talks about a
-YA, -YB, and   -YF version of the
  board. My M9312 manual (EK-M9312-TM-003 '81)
talks only in terms of
 bootstrap ROM part numbers. The DIP switch references in   the two documents
  conflict, even differing on the switch settings
necessary   just to boot into
  the console emulator.  ...
