PC Card

PC Card (formerly PCMCIA card) was a 16-bit peripheral interface standard used by early mobile devices. The specifications for PC Cards and its successor, CardBus, were developed by the (PCMCIA).
==History==
PCMCIA cards were originally designed for memory-expansion cards for data storage, based on development by the (JEIDA).PC Card Technology Primer, The Worldwide Organization for Modular Peripherals. Archived 1999-08-27. Because PC Cards were based on the 16-bit data bus standard, they also supported a range of other devices, such as hard drives, modems, and network cards. These were superseded by CardBus, based on the 32-bit PCI bus.PowerBooks with CardBus Support by Daniel Knight, Low End Mac. 2018-04-03.
