What is MSX ?
The MSX standard has been designed by a company called ASCII in cooperation with Microsoft which provided a firmware version of its BASIC for the machine. There is a widespread rumor that "MSX" stands for "MicroSoft eXtended". The MSX machines were produced by such giants as Sony, Yamaha, Panasonic, Toshiba, Daewoo, and Philips. The only MSX model ever sold in USA appears to be an early SpectraVideo machine.
