Thread: HP 1000 / 21MX / 2108 Mincomputer on fleabay

    Default HP 1000 / 21MX / 2108 Mincomputer on fleabay

    Looks like a nice project - haven't seen one in the UK advertised for a while... https://www.ebay.co.uk/itm/HP-1000-2...4AAOSwgfRcWC5H

    I have no connection with the seller... just like to see these things find a good home rather than being broken up

    It would be nice to see what was in the I/O slots. Having at least one serial board is a good starting point and also a picture of the tag inside with the boot ROM information.

    Not much in terms of I/O as far as I can see. There is one single BACI board in there. I/O is shown in one of the last pictures.

    IIRC - BACI - Binary Asynchronous Communications Interface?

    BACI = Buffered Asynchronous Communications Interface

    I didn't notice the extra pictures. That is a minimum to get it running. Looks like it would need the resistor plug or a battery pack to get it started.
