Introduction to PCMCIA
The PCMCIA (PC Memory Card Interface Association) standard
defines the physical dimensions, electrical interface characteristics and
software architecture of cards and slots that conform to the standard.
This means that a wide range of standard cards are available from a
variety of manufacturers to provide either data storage or peripheral
expansion.
The PCMCIA standard defines cards of three thicknesses; each is about
the same size as a credit card, uses a similar 68-pin connector and has a
3.3 mm thickness around its edge. The three types differ in the thickness
of the center section, as illustrated in Figure 10-1. The center section of
a Type I card is 3.3 mm thick; Type II cards are 5 mm thick; and Type
III cards are 10.5 mm thick. The PCMCIA port in your SPARCbook 3
can accommodate two Type I or II cards or one Type III card.
