    I need a monochrome monitor for an old computer system. (DB-9
    connector.)

    Originally a Heathkit which failed; repair might be too time
    consuming.

    Now have a PARCO 12" model 1231 AT, which seems to work, but will not
    display anything but a raster.
    Problem may be in the monitor (which was supposed to be OK) or in the
    interface. (I just plugged the DB-9 monitor plug into the DB-9 of the
    computer.)

    Any ideas? Anyone have the connector standards for these old systems
    - which may not be so standard after all.

    Any help/ideas appreciated. TIA -

    There were a few different systems around, what the compatibility of
    them was I've no idea. Monochrome signals are simple though, so
    standards crossing is sometimes an option.
