In recent years, Microsoft has taken steps to open up its historical software by releasing source codes under MIT licenses. Following releases of MS-DOS and GW-BASIC, the tech giant has now showcased something even older: a version of its inaugural software product.

This newly released version is a port of BASIC, designed for the Intel 8080, originally created by founders Bill Gates and Paul Allen for the Altair 8800. Microsoft detailed this release through its blog, noting that the version now available on GitHub was adapted for computers with MOS Technology 6502 processors.

The promotion of this software’s heritage highlights its essential role in the evolution of personal computing. While the Intel 8080 and MOS 6502 are noted for their historical significance, they represent pivotal developments in the computing industry.

Indeed, the 6502 was incredibly popular, prompting Gates and Ric Weiland to craft a version of BASIC that Commodore licensed for its PET model.

Interestingly, BASIC emerged as a heads-up user-friendly alternative amid programming languages like Fortran and COBOL, advocating access to computing for a broader audience.

While BASIC’s influence on the microcomputer era of the late ’70s is undeniable, it is argued that had Microsoft not developed it, another company would have stepped in to fill that niche.

With Microsoft’s recent initiatives, enthusiasts and researchers alike gain fresh opportunities to explore and learn from the rich tapestry of early computing history.
