    Macintosh Classic, no power at all

    Macintosh Classic, no power at all

    I would say, the second analog board seem to have voltage issues, I would test the 5v and 12v on the hard drive molex as a starter, then take it from there.

    Classic II, vertical collapse, no 12.6v out of flyback.

    Test Classic II logic board with SE analog ?

    Good evening! I recently acquired a Plus an SE FDHD and a Classic II, I recently recapped the Classic II but I wanted to test it before I start to recap it's analog board. I have a fully working SE, I notice the connector for the analog board it's the same, can I just connect it?
