I'll give him a shout. I won't be able to fit in a visit before I hop
in the car at the end of the week, but I can try to reach him.

It could. I do have multiple MS11-LD boards, but one per PDP-11/34
boardset, so I don't mind testing with them, I really do want a
dedicated board to stay with the 11/04. It seems from the behavior
that it's not a RAM fault so much as a demux fault or even something
wrong in the CPU (bad 74181) or, given the dual symptoms, faults in
both. Jason Timmons has promised me a DD11-PK if we can find it at
his house, then I could switch to testing with PDP-11/34 boards, and I
have multiple sets of those, all untested. My BA11-L has the larger
power supply, so it should be no problem to test the FP11-A I found,
once I am confident of the rest of the machine.
