I've had that happen to me once (out of 10+ PETs at my house). It was my
original 32K PET I got new in 1979. I think it was the $C000 ROM. The
symptom was that it would drop into the TIM prompt on power-on. Obviously,
losing a different ROM would probably have made the machine lock up. I
burned a 2532 with the first 4K of BASIC on it, and all was well.
Unfortunately, with the Static PET motherboards, and their non-2332 ROMs,
it's not trivial to just burn an EPROM. You'd need some sort of pin
swabber, but at least then you could use a common part.

If they come up

I've run into about 1/2 dozen PET's over the years which have had ROM's go
bad. Seems to be a real problem with the devices Commodore used.
