I found the microfiche for the KDF-11B on Bitsavers,
but they're missing
the one for the KDF-11A unfortunately!

So, if the CPU checks OK, maybe the DLV11-J has a problem with
interrupts? Is
there a DL11 diag you can run on it? (If not, I can whip up a simple
test to
check it out.)
The diagnostics manual mentions this:
NDLAA0.BIN DLVll-J (M8043 & FALCON) LOGIC TEST
But, the only XXDP disks I have are the ones from AK6DN, and that test
doesn't appear to be on any of them.
I have another memory board, but I know it's
bad, so I can't try
that!
Probably the one you have passes the memory diag, though, right?
I've run a memory test program I found that's not part of XXDP, and I
believe it's fine, but is there a test in XXDP I could run? I don't see
anything in the XXDP manual related to an M8044/MSV11. Now that I think
about it, I probably should find a way to really verify the memory is
working!
The MMU test from XXPP does pass, but I'm not sure if that also tests the
memory.
If it's not an issue with the DL11
interrupting, it sounds like we may
have
to dig into that diag to find out what it thinks it's doing when it
blows up.
If I can get my tool-chain working (currently downloading the abs-loader
isn't working right somehow), I'll see if I can figure out how to load
it,
and DDT along with it, and poke into it.
Locating the fiche would be another way to go...
