This led to the introduction of release 2.0 of the PCMCIA standard and JEIDA 4.1 in September 1991, which saw corrections and expansion with Card Services (CS) in the PCMCIA 2.1 standard in November 1992. It also needed interrupt facilities and hot plugging, which required the definition of new BIOS and operating system interfaces. It soon became clear that the PCMCIA card standard needed expansion to support "smart" I/O cards to address the emerging need for fax, modem, LAN, harddisk and floppy disk cards. Type II PC Card: IBM V.34 data/fax modem, manufactured by TDK This had the advantage of raising the upper limit on capacity to the full 32 MB available under DOS 3.22 on the 95LX. These cards conformed to a supplemental PCMCIA-ATA standard that allowed them to appear as more conventional IDE hard drives to the 95LX or a PC. The company was the first to introduce a writeable Flash RAM card for the HP 95LX (the first MS-DOS pocket computer). SanDisk (operating at the time as "SunDisk") launched its PCMCIA card in October 1992. It corresponds with the Japanese JEIDA memory card 4.0 standard. The PCMCIA 1.0 card standard was published by the Personal Computer Memory Card International Association in November 1990 and was soon adopted by more than eighty vendors. Originally introduced as PCMCIA, the PC Card standard as well as its successors like CardBus were defined and developed by the Personal Computer Memory Card International Association (PCMCIA).Īlthough originally designed as a standard for memory- expansion cards for computer storage, the existence of a usable general standard for notebook peripherals led to the development of many kinds of devices including network cards, modems, and hard disks. In computing, PC Card is a configuration for computer parallel communication peripheral interface, designed for laptop computers. Personal Computer Memory Card International Association
