The MSX 1 was a typical home computer, well suited for games and programmable in Basic. The MSX standard was developed by the Japanese department of Microsoft (later ASCII) in Japan and manufacturers could build machines with the MSX logo under license if the standard was followed. This way a large market was developed for software and peripherals for MSX and many companies competed with hardware.
