Microsoft Multiplan

Microsoft Multiplan was an early spreadsheet program and the first piece of application software from Microsoft to target end users. It was introduced in 1982 with versions for CP/M, MS-DOS, and the Apple II. Versions for many other computers, including various TRS‑80 models, soon followed. Multiplan was the first (and for a while the only) third-party software package available when the Apple Macintosh was introduced in 1984.

Level III BASIC

Level III BASIC was an enhanced version of Level II BASIC for the TRS‑80 Model I. It was created by Microsoft, also the authors of Level II BASIC, but sold by GRT Corporation on cassette for $49.95. Level III BASIC was said to be the first consumer product from Microsoft, which had previously sold only to manufacturers.

Rather than sell Level III BASIC directly to consumers, Microsoft decided to release it through GRT Corporation in 1978.
