d this a year or two back with about 30 x SID, VIC, and PLA chips out of C64's. I heated them in the oven at about 250 for 15 minutes. None of them showed any more signs of life than before I tried it, unfortunately. -- -Pete Rittwage

o restore their programability, but I don't remember the specifics. I > tried a few at 450F for 15 minutes, but they still won't program. > Are you positive you have the programming voltage right? I have a box of really old ones and every time I have to research a little to find the right voltage for different brands. All 27128's are not the same, for example. Some are 12V, some may be 25V (for example). My programmer only has one setting in the software, and I have to change jumpers to modify programming voltage. My USB programmer won't touch any of the old ones because I assume it can't provide enough voltage/current for them. -Pete Rittwage
