  Darn! I've seen those cards but I can't remember what they are.

  OK I finally got the grey matter working and I remember what those cards
are. They're DOS coprocessor cards. Yes, your HP can run MS-DOS. Somewhere
I have some of the cards but I never found software for them. If you got a
drive with your system, look at it carefully and see if it has the
necessary SW. If you find the SW, I'd love to get a copy.
