Basic/Four

Basic/Four is a variety of Business Basic which originally ran on computers of the same name introduced in 1971.

Basic/Four sold small business minicomputers that were assembled from Microdata Corporation CPUs.

MAI Basic Four (the company) originally sold minicomputers, but later offered superminicomputers and microcomputers.

The computers ran an operating system with the BASIC interpreter integrated.
