Architecture

Currently, there are three types of PC cards. The 1784-PCMK card is a Type II card.

All three types of PC cards use the same
68-pin connector. The pins are in two
parallel rows of 34 pins. When inserted
into the PCMCIA slot on your computer,
the connector mates with a single molded
socket.

IMPORTANT

If the PCMCIA slot in your computer is thick enough to
accommodate a Type III card, then it can also accommodate a
Type I or II card.
