11/34A/RK07 not booting. Help wanted - test-drb@ccmp.vtda.org

19 Nov 1998

...
 This time it's the PDP-11/34A system. I was able to
get it checked out and
lit up okay. It has the Programmers Console (KY11-LB) and an M9312
Bootstrap/Terminator module plus RK611 and UDA50 drive interfaces. 
Switch 2 is OFF on the 9312 therefore, registers printout onscreen and the
system prompt (@ in this case) appears after CNTL/BOOT keys are
simultaneously pressed. Seems okay so far. However, the 11/34-11/34A user's
manual says the prompt should be a '$' (?). 
Hmm - "$" is what I've always seen with the 11/34A ROM's.  Is
it possible that you aren't running the standard 11/34A ROM's?
What are the DEC ROM numbers on your 9312?  The part numbers
will be of the frm 23-nnnA9, where "nnn"=752 for the RK06/07
bootstrap.  Sometimes the "23-" is left off.

But the register printout is correct...

...
 Upon trying to boot the thing I am instructed to simply
type DM onto the
terminal and the 11/34A will boot off the RK07 #0. Well, nothing happens. 
Does the DM echo?  What if you type some nonsense characters - like YY?
