I was trying to put together HDD for my II+ and we were sourcing the parts from Weirdstuff (when they were still at Sycamore Drive in Milpitas) Sapphire was running his BBS (this was...

    Xebec SASI controller utilities disk image for Apple II needed

    Help Diagnosing and Finding Ram Replacements for IIe

    I find it hard to believe that all eight chips would fail at the same time. While Micron parts have been problematic, it's extremely unlike that all eight would fail at the same time. clean the MMU and CPU while you're spraying away with deoxit.

    Any rare apple II accessories I should keep and eye out for?

    not sure why you would think the macroshaft's cp/m card is rare; it was extremely popular back in the day and there must be hundreds of thousand of them out there.

    Scsi st-277n interleave etc settings

    format unit command has no provision for interleave. the direct access device is presented as a continuous stream of logical blocks. drive geometry and any interleave that might be in use is entirely internal to the drive. while it is possible the drive vendor may have vendor unique setting for...

    Scsi st-277n interleave etc settings

    You don't control the interleave factor of SCSI direct access block devices. SCSI spec has no provision for such setting. There may be vendor unique command or vendor specific mode page for it, but that would vary for each vendor/model drive.

    Apple III Keycaps / Key stems needed

    The III keyboard with tophat under the keycaps uses ALP's short stem key switches. It looks like the keyswitch for the arrow keys are not standard ALPs keyswitches (deeper with four soldering points) The caplock keys are special, you can probably source one from early models of IIe (ones with...

    Modem for Mac Color Classic

    It's not compatible. Just get a din8 to db25 cable and pair that with a generic external modem, though I don't quite understand why an analog modem is still being employed.
