This makes sense. Since the Poqet was 8088 only, I never would have
searched for it (FreeBSD required, at the time, 80386 or better). I learned
something new today about a topic I thought I had nothing of note left to
learn in. Thank you.
They do seem the same as PCMCIA Type1, Rev1/0, other than that the Poqet

Yea, those PCMICA I/O cards were introduced with PCMCIA 3.0, and the modem,
scsi cards are I/O cards (meaning, they had the pins to do I/O port
accesses on a x86). The earlier Type 1 cards were purely memory cards and
lacked the pins (or the pins were defined in a different way).
