Well done.
Of course the system now still won't boot (I can
hear the drive
head move, and then the RL02 FAULT light comes on) but it's likely
the OS/8 image got clobbered when the chip failed and the CPU
started writing to odd places.
Hmm... I don't think filesystem problems will cause the Fault light to
light up, just problems within the drive. You may need to trace back
all of the causes that sum up to "Fault" to see what's going on.
You can't write-protect the pack
either, since OS/8 swaps in and out frequently to maintain such a
tiny "footprint" in core.
Unfortunately not.
Anyhow I'm leaving tonight for three weeks of
vacation in sunny
Crete so it can just wait until I get home!
