I recently acquired an Apple //e (M/N A2S2064) computer. Upon powering it up, I have found that all the keys repeat indefinitely, until i press a new key and then that key repeats forever. I have looked all over the internet and have found a few forum threads talking about this, but I havent found one with a solution. The computer has a 64Kb ram expansion card and the card that the dual disk drive plugs into as well as color graphics. If I remove both of those, I get the ] prompt and then a repeating key. I have done a system diagnosis (ctrl+open apple + closed apple + repeat) and I get system OK. Does anyone have any advice on how to fix this?
