I've kept the chip in case it is one that it is needed, but I suspect the
kind of precise soldering involved is beyond my abilities. To be honest,
the only thing I've ever soldered before are power supplies, so I'm going to
have do a fair amount of practicing (not on the PET!) just to replace the
cap that's gone, never mind fixing the ROM. I was hoping that if the ROM
turns out to be something essential, I might be able to get someone (for a
suitable fee) to burn a new one for me, though that's assuming blank ROMs of
the right type can still be obtained... Anyway, hopefully it won't come to
that.
