Exchangable Card Architecture
PC Card is a technical standard specifying an expansion card interface for laptops and PDAs. The PCMCIA originally introduced the 16-bit ISA-based PCMCIA Card in 1990, but renamed it to PC Card in March 1995 to avoid confusion with the name of the organization. The CardBus PC Card was introduced as a 32-bit version of the original PC Card, based on the PCI specification. CardBus slots are backwards compatible, but older slots are not forward compatible with CardBus cards. Although 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. The PC Card port has been superseded by the ExpressCard interface since 2003, which was also initially developed by the PCMCIA. The organization dissolved in 2009, with its assets merged into the USB Implementers Forum. Applications Many notebooks in the ...

Personal Computer Memory Card International Association
The Personal Computer Memory Card International Association (PCMCIA) was an industry consortium of List of computer hardware manufacturers, computer hardware manufacturers from 1989 to 2009. Starting with the PC Card, PCMCIA card in 1990 (the name later simplified to ''PC Card''), it created various standards for peripheral interfaces designed for laptop computers. History PCMCIA was based on the original initiative of the British mathematician and computer scientist Ian Cullimore, Ian H. S. Cullimore, one of the founders of the Sunnyvale, California, Sunnyvale-based Poqet Computer Corporation, who was seeking to integrate some kind of memory card technology as storage medium into their early DOS-based palmtop PCs, when traditional floppy drives and harddisks were found to be too power-hungry and large to fit into their battery-powered handheld devices. When in July 1989, Poqet contacted Fujitsu for their existing but still non-standardized Static random-access memory, SRAM mem ...

Kodak DCS 300 Series
The Kodak DCS 300 series comprises two cameras, the DCS 315 and DCS 330. They are professional-level digital SLR cameras built by Eastman Kodak's Kodak Professional Imaging Solutions division. They were based on the Nikon Pronea 6i APS SLR camera and were aimed at a lower price point than other models in the Kodak DCS range. The 1.5 megapixel DCS 315 was launched in 1998, while the 3 megapixel DCS 330 was launched in 1999. Technical description The two cameras have charge-coupled device, CCD image sensors with different sizes and shapes, both of which are smaller than either 135 film or APS-C film frames. The 315's imager has a crop factor of 2.6 relative to 135 film ("35mm"), while the 330's is larger, with a factor of 1.9. The Kodak modification to the Pronea 6i involved removing the camera's film back and mounting a Kodak digital back. This not only covers the back of the camera, but also extends beneath it, approximately doubling the camera's height. This was required ...
