Hello friends! I figure it's about time I created an account on this site given how long I've used Apple computers.
I just took my non-enhanced Apple //e out of storage yesterday and spent several hours using it successfully. Today it would not power on (no beep, no LEDs). I isolated the problem to the Disk ][ drives: when both are disconnected from the Disk ][ controller card, the computer starts normally.
Next I wanted to figure out whether the problem was just one drive or the controller card. Since I believe the drives are interchangeable, and because I didn't know if the controller would work with a drive connected only to drive connector 2, as a first step I decided to plug the drive 2 cable into the card's drive 1 connector. This resulted in a flickering Apple //e power LED and an unhappy crackling sound from inside drive 2. I opened drive 2 and don't see any obviously burnt components.
I'm now undecided about what to do next. I'm concerned that I've fried drive 2 and that (if the problem is the controller card) if I connect drive 1 I'll fry it as well. Any suggestions?
