Forrest M. Mims’s copy of BASIC for the Altair, around 1975

Journalist and early Altair microcomputer owner Forrest M. Mims III owned this BASIC tape. During the 1970s, microcomputers began to sell to individuals, many of whom used a programming language called BASIC. BASIC for the Altair was one of the first products of Micro-Soft (now Microsoft), whose early employees are shown in the photograph.
