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. Ian Message was sent through the cbm-hackers mailing list
