I've just obtained a Commodore 1571 disk drive
(double sided 5.25"). I've
pulled the case and tested the PSU -- it's on a separate PCB with a
plug-in output lead and the voltages are marked on the board. And being a
simple linear PSU with 3 terminal regulators it doesn't even need a dummy
load.
Anyway, the PSU is fine. I reconnected it to the rest of the drive and
turned it on again. Both frontpanel LEDs came on and the spindle motor
started. A little later the 'Drive' LED turned off and a little after
that the spindle stopped. This is what I believe should happen (according
to the user manual), but should the head restore to track 0? It doesn't.
Do I have a fault to find?
I don't *think* so, but the proof of the pudding is, can you get a directory
out of it? Commodore drives are pretty resilient.
