Although Microsoft did not invent BASIC, their founding product was a BASIC interpreter for the Altair computer. The descendants below includes Microsoft's BASIC-80 (MBASIC), BASIC-86 (pre-GWBasic), BASIC for Mac, BASIC Compiler 86/88, Basic Compiler for Mac, and Professional Development System 7.x. IBM Personal Computer Basic Compiler, GW-BASIC, QuickBasic, and Visual Basic are listed separately.
Please note: If you are looking for BASIC-86 for a specific machine, it was probably bundled with the vendor's Operating System package. You can find many customized versions in MS-DOS 1.x and MS-DOS 2.x OEM system disks.
The Seattle Computer Products version below was designed for SCP 86-DOS, but will also run under MS-DOS.
Wanted: full disk dumps and manual scans of the complete BASIC products.
