In 1989, with the mobile computing industry kicking at the seams of its infancy, a number of portable storage cards were appearing on the market.

John Reimer an executive and engineer then working at Fujitsu on mobile computing solutions, recognized that different, incompatible cards were being produced by different companies. In order to avoid complete chaos and to insure that anyone buying a mobile device would be able to choose from a variety of companies for their removable media, Mr. Reimer decided, there would have to be an established standard to protect both consumers and businesses.

He soon found that he wasn't alone, and, with the assistance of his colleagues working at other companies, he successfully secured funding and agreements from a small number of corporations that would spearhead the non-profit organization PCMCIA (Personal Computer Memory Card International Association), run by a board and a group of elected officials, and chaired for a number of years by the founder, John Reimer.

The idea caught on quite well. "By 1991, PCMCIA had defined an I/O interface for the same 68 pin connector initially used for memory cards. At the same time, the Socket Services Specification was added and was soon followed by the Card Services Specifcation as developers realized that common software would be needed to enhance compatibility." Today, anyone would be hard pressed to find a laptop computer or a PDA without a PCMCIA slot or a Compact Flash slot, (Compact Flash] cards being adaptable to PCMCIA slots with a simple adapter). PCMCIA now boasts over 200 member companies and affiliates.
