Well, to make troubleshooing the system simpler, I've pulled nearly every
Q-bus module from it. I still got the same
?06 HALT INST
PC = A0050419
error message even after I pulled everything except the M7606 CPU module,
the two 4Meg M7608 Memory boards, the RDQX3 controller, and the TK50
controller.
Taking things further, I pulled one of the memory boards... rebooted...
Success! One of the memory boards I had was a National Semiconductor M7608
"clone" board. It either inherently sucks or was functionally unsound.
Pulling that board fixed the problem. Of course now I've got a 5Meg
MicroVAX II. So now I'd better go pickup an M7609 :-)
Anyway, my machine has now happily made it to the Nboot prompt. So my
quest continues into phase 2.
