to swap boards.
Your help is much appreciated, Tony!
But, if you know what and why to do something, a swap is not a crime.
Of course, you swap only *one* board. If that solved the problem, you
can label the swapped board with a note of the seen symptom.
I say that it solved the problem, not fixed it. That's for later ...
What I can tell you is how to trace that fault. The
diagnostic seems to
be saying that the top bit (bit 15) of CSR1 could not be cleared. So,
let's grab the prints (but not tonight, it's late...) and find CSR 1,
find out what should set and clear bit 15, and see what's going on there.
That's what I'd do, the diagnostic output is descriptive enough. However,
... I don't have the printset of the RK611 :-( and it is not on bitsavers :-(
I'm afraid I will have to put the RK07/RK611 on hold for a short time ...
