What was more popular MSX machines or CP/M in Japan?Japan stuck with CP/M for longer than the USA. The Epson QX-10 came out in 1983 and it had a Z80 and ran CP/M 2.2. A little later they released the QX-16 a dual CPU (z80 & 8088) that ran either CP/M or MS DOS 2.2. So by then the handwriting was on the wall. Of note, the QX-16 does not use PC format disks since it was released just before the IBM PC came out. While it runs MS DOS, it is not IBM PC compatible for IBM only programs or graphics. So it too died a rapid death.
