    Reviving a Power Macintosh 7500/100

    I have a spare 7500 logic board that is working if you are interested/need it. Would only ask what I paid for it+ shipping. Feel free to DM me.

    Macintosh Quadra 840AV Post Issues

    First off, thanks to @jmacz for the repair work on this board. It's in WAY better physical and operational condition than when I first got it. After a busy week at work I finally had a chance to spend some more time testing this board. From a cold start (ie no power for over a couple hours)...

    Mac SE Floppy Drive Compatibility

    Here's a couple of pictures. I have the original box so that's why I believe it came that way from the factory. Never knew this was an option, any other dual floppy SE I've seen has been 800K. Anyhow, got around to swapping parts around today. Replaced the logic board,  metal frame (old one was...

    Mac SE Floppy Drive Compatibility

    Hi All, I recently purchased a Mac SE Dual Floppy model on eBay because the case was in very good condition. The seller said it didn't power on, but this was vague so i bought it anyway to see if I could figure out what might be wrong. Well, it suffered the all-too-common red battery explosion...

    Centris 650, mixed emotions

    The hard drives are SCSI 3.5", 50 pin. If I recall someone did make an adapter for IDE drives, but it was pretty expensive. I think you'd be better off just picking up a used SCSI drive somewhere.  The laser printer cable is likely just an 8 pin serial cable. It will resemble the keyboard cable...
