Actually, the first HP _handheld_ with a card reader was the HP65, which
came out a couple of years before the HP67. I have both machines, and
they're very nice :-)

I have a _few_ cards, but they're not up for grabs. I have an HP9100B (a
_real_ calculator ;-) that uses them and one day I'll get round to
replacing the card reader roller and using said reader again. The machine
is perfect apart from that.
