I'm working with a user in Europe to debug an Apple IIc+ that he purchased from me. When I had it, it powered up and generated video, but the disk operation was untested. It had been in storage for an extended period of time, and I never had any disks for it to use for testing.
His report of the current status is:
General test does not show anything, but this won't show up any drive related problems, just memory/processor. Switching from turbo (4Mhz) to normal (1Mhz) mode works. Keyboard works. Drive and external drive connector do not work. Even replacing the drive by Floppyemu or connecting external drive is not solution - it should work even with failure of internal drive but this does not work.
I am looking for any suggestions for anything else that he can try. Since the failure seems to affect both the internal drive as well as the external connector, that seems like something fairly major is not working.
Any ideas would be appreciated. Thank you ... Dave
