MSX-DOS

Operating System

MSX-DOS is a discontinued disk operating system that Microsoft's Japan subsidiary built for the MSX standard of 8-bit home computers, released in 1984 with ASCII Corporation helping standardize the hardware and software around it. It combined elements of MS-DOS 1.25 and CP/M-80 2.2 and was binary compatible with CP/M-80, letting MSX owners run its large existing software library cheaply. The system used a monolithic kernel with COMMAND.COM as its command line interface, and its main purpose was to give MSX's BASIC environment real disk capability at lower cost than memory cartridges and with far more storage than cassette tape. It is no longer maintained but is remembered as a bridge between CP/M software and the MS-DOS world on 8-bit machines.

Who wrote MSX-DOS?

Tim Paterson wrote the core of MSX-DOS under contract to Microsoft in 1983 and 1984.

Microsoft's Paul Allen asked Tim Paterson, the original author of 86-DOS and MS-DOS 1.x, on August 10, 1983 to produce a Z80 version of MS-DOS for the MSX standard. Paterson did the core work, with ASCII in Japan creating the I/O System for the actual MSX machines. The beta test version was officially delivered on October 26, 1983, and Microsoft accepted final delivery on April 23, 1984.
