    We have a daughter board here that plugs into the header
    and brings out a serial line.  I've only seen one of these
    devices, and it follows whoever is working on the latest
    hardware/booter/kernel debugging puzzle on the 2700.  

    Is it a pretty simple board, with an SCC and some glue,
    so an intrepid explorer with a breadboard could probably
    build one.  I just asked one of our hardware guys if he
    has a skematic lying around.  Needless to say, it was only
    used for internal debuging, so there is a chance that the
    files are lost to antiquity.  More news later.
