  There's no HP Field Guide that I know of. Several times I've statrted to
put up some webpages about some of the more popular HP units but I never
finished it.

   FWIW The small cards are called "DIO" or "DIO-I" cards. The larger cards
are called "DIO-II" cards. I don't remember what DIO stands for though. But
I could probably find out if it matters.

  Darn! I've seen those cards but I can't remember what they are. I'll have
to go check the HP catalogs but they're across town so it will be at least
a couple of days before I can.
