Sord (today, the Toshiba Personal Computer System Corporation) announced the M200 Smart Home Computer series in September 1977.
Japan's first desktop computer, the M200 combined a CPU, keyboard, CRT display, and floppy disk drive into one integrated unit. It ran on the Zilog Z80 processor and was standard equipped with the MF-DOS disk operating system. The computers were supplied with the SORD Extended BASIC plus programming language. This variant of BASIC ran on MF-DOS and had an intermediate language structure that consisted of an easy-to-use interpreter and a fast, highly efficient compiler.
