Last night was the primary application of power (Read: Smoke Test)
for my PDP 11/44. Everything spun up, the room lights stayed lit,
and, so far, no one complained about the noise the fans made. 
However, I have a problem. The diagnostic rom says "?22 CP HUNG"
and a T/E trace says "CONSOLE -A7".

Does anyone have any guess as to where I should start looking?
