About Western Digital

Western Digital Corporation (often abbreviated to WD) is one of the largest computer hard disk drive manufacturers in the world.[2] It has a long history in the electronics industry as an integrated circuit maker and a storage products company. Western Digital was founded on April 23, 1970 by Alvin B. Phillips, a Motorola employee, as General Digital, initially (and briefly) a manufacturer of MOS test equipment. It rapidly became a speciality semiconductor maker, with start-up capital provided by several individual investors and industrial giant Emerson Electric Company. Around July 1971, it adopted its current name and soon introduced its first product, the WD1402A UART.

WDC introduced several landmark products during this time, including the MCP-1600 multi-chip, microcoded CPU. The MCP-1600 was used to implement DEC's LSI-11 system and their own Pascal MicroEngine microcomputer which ran the UCSD p-System Version III and UCSD Pascal. The processor was also used in several single-chip floppy disk drive controller chips, notably the FD1771.

Much of the mid-to-late 1980s saw an effort by WDC to use the profits from their ATA storage controllers to become a general-purpose OEM hardware supplier for the PC industry. As a result, WDC purchased a number of hardware companies. These included graphics cards (through their Paradise subsidiary, purchased 1986), core logic chipsets (by purchasing Faraday Electronics Inc. in 1987), SCSI controller chips for disk and tape devices (by purchasing ADSI in 1986), networking (WD8003, WD8013 Ethernet and WD8003S StarLAN). They did well (especially Paradise, which produced one of the best VGA cards of the era), but storage-related chips and disk controllers were their biggest money makers. In 1986, they introduced the WD33C93 single-chip SCSI interface, which was used in the first 16-bit bus mastering SCSI host adapter, the WD7000 "FASST"; in 1987 they introduced the WD37C65, a single-chip implementation of the PC/AT's floppy disk controller circuitry, and the grandfather of modern super I/O chips; in 1988 they introduced the WD42C22 "Vanilla", the first single-chip ATA hard disk controller.
