(MSX) A Range of computers created in an attempt by the industry to create a standard for home computers, similar to VHS did with home video. The basic MSX machine contained a Z80CPU working at 3.58MHz. MSX machines were produced by such giants as Sony, Yamaha, Panasonic, Toshiba, Daewoo, and Philips. The MSX standard was designed by a company called ASCII in cooperation with Microsoft who provided a firmware version of ITSBASIC for the machine. Because this BASIC version was an extended version of MicroSoft Basic, it was called "MicroSoft eXtended BASIC" Hence "MSX". Microsoft also produced MSX-DOS - a stripped-down version of MS-DOS. Extensions to the MSX included MSX2, MSX2+ and TurboR. FAQ . (1999-02-26)
