    I suspect that there's a microprocessor in there somewhere...

    Maybe some military secrets? The control system for a nuclear power plant? The complete original script of Back to the Future?

    Let us know!

    Looks like it needs to be pressure washed. Probably never been cleaned since new

    Default Oh, the woes.....

    A bitter-sweet story this one.

    At first, I got nada from the system. I finally figured out that the floppy drive was shorting somewhere, and with the power to that removed (and replaced with a floppy drive from my IBM PC 5150) then the unit turned on.

    The monitor was dead, and so I had to borrow the IBM colour monitor from my 5150, and also, the graphics card (as the original was Mono).

    Then the system booted right up. The Seagate ST412 booted straight into IBM PC DOS 3.1, which considering its age, is quite stunning really. Even the floppy disk that I found in the drive was completely readable.

    I quickly made a boot floppy, and then using my XT-IDE interface, copied the hard drive contents to a CF card.

    Now for the bitter part. During this process, I came to discover that my IBM PC 5150 will no longer power up. It displays sign of life briefly, but then nothing. I tried a power supply swap, and removed everything but the motherboard, and it still 'pops' briefly, but doesn't actually start.

    A project for another day I think.

    Directories on disk:

    DOS
    FACTDATA
    MTN_TAPE
    MULTIFAC

    ORIGINAL
    WORDSTAR
    WS2000

    ...any clues on what these might be?

    Re the 5150 - check for shorts across the 3-pin capacitors.
