    I doubt it. While I don't know for sure, there's likely no way to remove the arm from the shaft of that motor without disassembling the...

    I think don't power-cycle the Lisa itself --- just turn the Lisa on and reset it several times via the Reset button on the back. If I'm...

    Hmm... 5+ times isn't the same as a campaign of a bunch of resets and arm movement attempts right after the other, but it's more than...

    But to your point in the message: if a Widget isn't making progress after a few dozen resets like this, I'd assume some other problem or...

    Sorry to hear about this @ried , and thanks for trying. The objective is not just to turn the spindle, though, it's to get the arm...

    Can third or fourth the recommendation. Needle-nose pliers to tug that pin right out of there :)

    More to know about the servo: Roughly and abstractly speaking, a "servo" is a device that moves to a specific place by measuring where...

    Good. This is what it looks like when a Widget is waking up, in my experience. Keep at it.

    This is a setback, but it may not be a very big deal. The connector is an eight-pin connector for a flat-flex ribbon with what looks...

    52 is an "I/O board COPS error", and I'm not sure why an expansion card should cause that kind of trouble. How soon does it come up ---...

    Hmm about the Widget --- so after repeated resets, or startups and shutdowns, the heads don't seem to advance any further than they did...

    That's longer than I've ever run a Widget continually :) I think my record is probably an afternoon or so. It would be interesting to...

    Happily 341-0289-D is only a ROM; you could make a new one. There are other, real unobtainium chips on your Widget. If I had to choose...
