ABSTRACT
The Personal Computer Memory Card International Association (PCMCIA) interface allows small thin cards to be plugged into laptop, notebook or palmtop computers. It was originally designed for memory cards (Version 1 .O) but has since been adopted for many other types of adapters (Version 2.0), such as fax/modems, sound cards, local area network cards, CDROM controllers, digital I10 cards, and so on. Most PCMCIA cards comply with either PCMCIA Type I1 or Type 111. Type I cards are 3.3 mm thick, Type I1 take cards up to 5 mm thick, Type I11 allows cards up to 10.5 mm thick. A new standard, Type IV, takes cards which are greater than 10.5 mm. Type I1 interfaces can accept Type I cards, Type I11 accept Types I and I1 and Type IV interfaces accept Types I, I1 and 111.
