I've been working on getting a PDP-11/23 running for a while now, with
various amounts of success!
I had it in a state where I could boot XXDP from a virtual TU-58 and
everything seemed to work pretty well. I then got ambitious and got an RL02
and an RLV11 (M8013+M8014), and last night I tried to get the RLV11 to pass
the unconnected diagnostics that just test the controller.
I tinkered with it for a while, but never got it to work. Then, in between
trying a few things (but without touching the hardware), the machine seemed
to get very flaky. Right now I can still boot an XXDP tape image, but as
soon as I try to do anything it dumps me back to ODT:
NOT ENOUGH MEMORY TO BOOT XXDP-XM
BOOTING UP XXDP-SM SMALL MONITOR
XXDP-SM SMALL MONITOR - XXDP V2.6
BOOTED FROM DD0
28KW OF MEMORY
RESTART ADDRESS: 152010
TYPE "H" FOR HELP
I tried removing the RLV11 boards, returning the machine to it's former
state, but I have the same issue.
I'm pretty new to all of this and always have trouble figuring out what the
next debugging step should be.
My machine is a PDP-11/23 with a H9273 backplane. I have, in this order
from the top: M8186, M8043, M8044DF, and an M8012 at the bottom.
Any help would be appreciated! Thanks!
