    Classic I seeks floppy on boot

    I have a Macintosh Classic I which has been recapped, logic board and the analog board. After recapping the logic board I tested it. The thing booted up as it did prior. I moved on to the analog board as the CRT was just a bit wobbly. While testing after that recap it will seek the floppy...

    Does anyone know the part number for the analog board yoke connector? This is a 630-0395 model board with the larger connector. I have one that is fairly yellow and would love to replace it.

    Squeeze image compression

    I am working on extracting images from a clipart collection called "Electronic Clipper".

    The disk at SCSI #0 has been remove while in use

    Normally my Mac Classic II works just fine. But if I connect up a spinning disk to the external port and attempt to copy a large number of files off to the internal SCSI2SD I get the error message "The disk at SCSI #0 has been remove while in use" and the SCSI2SD disconnects.

    Apple IIe Disk card ID needed

    I recently acquired an Apple IIe. I'm trying to get it to work with my Floppy Emu but not having much luck. That said I don't really know what I am doing when it comes to Apple IIe.

    m68000 modern replacement?

    Wondering if the modern M68HC000 version of the 68000 chip family can be a drop-in replacement for an M68000FN8. Anyone tried this? I'm pretty sure the only differences is one is CMOS the other is HMOS. This Atari forum post seems to indicate it...
