11/34 up! (sort of)

Woohoo, I finally, after over a decade of being somewhat out of the pdp11
hobby, have managed to bring back to life one of my pdp11/34s!

It's a plain 11/34 with dl11-w, ky11-lb, ms11-L, rl11 and a M9312
terminator/boot rom board.  I have an emulex controller and some fuji 160s
I'll tack on later so I can run 2.9BSD once I get the basic build confirmed
safe.

It's not in great shape at the moment, apparently, as these xxdp 2.5 diags
are crashing left and right.  But it at least boots the os and tries.

I initially had, but mysteriously lost the console emulator/ODT
functionality, seems it's starting at 165000 instead of 165200 at poweron.
Maybe a 9312 switch mis-set...  So I'm booting from the panel by calling
the address of the ODT or the rl02 boot rom, which does the trick.


Would anyone care to recommend some xxdp diags I should be running or next
steps to isolate what's wrong / right with it?

thx

P.S.

I tried to boot rsx11m v4.1, but got a strange crash with all zeroes in the
stack and registers.  What might that indicate?
