Screenshots from MS-DOS 3.21 (Oki OEM)

This is Japanese MS-DOS Version 3.21 for OKI's laptop computers.

During the 1980s Japanese bubble economy, many Japanese electric companies entered into the personal computer industry. Oki Electric Industry Co., known as a manufacturer of printers and telecommunication equipments, also produced laptop computers. However, the Japanese PC market was occupied by IBM, NEC and Fujitsu, and each of them had own computer architectures. In 1986, Microsoft Japan formed the AX Consortium to develop a uniform computer architecture that allowed IBM-compatible PCs to handle Japanese text via special hardware chip JEGA (Japanese EGA). Oki was a member of that. Nowadays, no one of that members is producing PCs in Japan.

Before MS-DOS 6.2/V, OEM adaptation kits (OAKs) of Japanese MS-DOS included a 'reference' version of MS-DOS for AX machines.
