    I suspect the power supply in my LC is bad. Before spending time/money fixing it, any reason I can't remove it and jumper in the +5, -5, and 12v supplies, using an Allied Al-A300 ATX supply I've got?

    Thanks.

    A dead PRAM battery will keep it from booting, as I recall. I'd start with that. Remove the old one and see if another battery will get it going. You don't have to buy the fancy one - just get close to the nominal voltage to see if that's the issue.

    Again, "An Apple II LC?" ! Really still working?
    Or is it a Liquid Chromatography system?
    Or a ...

    It's an Apple LC (I, I presume). :)

    Already put in a good battery.

    Just want to see if it will boot, with a known, good, power supply.

    Thanks.

    No, I don't. :)

    There are NO Roman numerals after LC, so I presume it's the model BEFORE the LC II?

    Ah, this one then?

    You do realize that, even if it works, it has negative value and you may have to pay someone to take it away? I think I have one in my basement.

    No, again. ;)

    Check ebay. The entire systems, which I have, can go for quite a bit of money --to collectors, I assume.

    I'll have to look into that. I've got several models from Apple IIe up to a G3 Mac. I'd love to turn them into ...anything... besides scrap.
