Last weekend I may have fried my disk drives on an Apple //e. Are the drive toast? Read below, please. After a motherboard swap I fired it up, heard a tiny tiny pop, smelled smoke and got no disk activity. After swapping disk drives and controller cards I was able to boot up. The cable's red wire and pin 1 were oriented correctly -- but perhaps it was off a row, or not in full electircal contact (or same with edge connector on board)?
I've done that, most likely damage is the 74LS125 chip on the analog board inside the drive. The chips are socketed so replacement is easy
