I recently acquired a NIB Apple IIe card and put it in a Quadra 605. Everything works just fine, except when I tried to hook up a 5.25 floppy drive (A9M0107), the IIe card doesn't seem to recognize it. I've tried two different drives that were claimed to be in working order, and neither works for me. I have some old 5.25 disks I'd like to use, so this is driving me crazy. Unfortunately, I don't know if I have two dud disk drives, or a dud IIe card or Y cable. As I said, this card was NIB (shrinkwrapped), although the Y cable is pretty discolored. Any ideas how I can narrow down the problem?
