Hooray!

I'm not surprised about the PLA and the RAM... in that order, they are
the most common things to fail.  A bad CIA is also not all that rare
(because of ESD to the User and Joystick ports).  All that *plus* ROMs
- that's a bit much for one board, but hardly unheard of unless the
PSU flakes out and jolts everything.

Good to hear the monitor fix was simple once the symptoms were fully
understood.  I've never had to repair the CRT control board in a PET,
but since it's not a readily available part, repair is more of an
option than replacing.

I've only ever seen a couple of PET64s ever, so it's wonderful to see
one brought back from the brink.
