OT: Reflowing GPUs and the fruit company (was Re: Resurrecting integrated circuits by cooking them.)

Yup, I've had this issue too and it does come back every so often. The first time it lasted nearly a year. The second time, it lasted about 9 months. At some point it will fail to work, or I'll wind up actually damaging the chip and then it won't work anymore. Come to think of it, my very first

Re: Apple (Lisa 2/10) MAC XL UNIX 5

Depending on what version of UniPlus that is, a version was found a few years ago which was imaged and is installable.  UniPlus is a bunch of floppies (a bit under twenty off the top of my head), not just one, if you have the full set and it's a different version than what's out there already and

Pet 8032 in 40 column mode?

Hi, I seem to vaguely recall that there was a poke to enable 40 column mode on the 8032, anyone know what it is? Couldn't find it in the Pet FAQ.

Commodore Pet 8032 keyboard repair - conductive or capacitive?

I have a pair of 8032 Pets. One of them has a short on the motherboard that causes the fuse to blow whenever it's turned on - looks like its previous owner tried to repair it as the power connector is a bit burned and a new, non-pet power connector has been added. Likely one of the power
