PC Card

PC Card is a form factor standard peripheral interface standard for notebook computers introduced in 1990. Originally intended to provide expanded storage space for mobile computers, the interface was quickly adapted for network cards and other upgrades. Although it underwent numerous revisions (designated by roman numerals I-III), it was eventually superseded by the Express Card standard in 2003. Several companies with high volume sales to government agencies and institutions still offer PC Card slots for backwards compatibility with older equipment.
