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'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
The MMU test from XXPP does pass, but I'm not sure if that also tests the
