About this tag
The osi tag on WindowsForum.com covers discussions about open-source software releases from Microsoft, particularly the historic 6502 BASIC interpreter. The tagged content highlights Microsoft's publication of the assembly-language source code for its 1970s-era BASIC interpreter under a permissive MIT license on GitHub. This release preserves an important piece of computing history, allowing hobbyists, historians, educators, and developers to study, build, and reuse the code that powered early home computers. The threads emphasize the technical and historical significance of this open-sourcing effort, focusing on the original Altair/8080 BASIC and its port to the 6502 microprocessor.
Nearly half a century after those first keystrokes on primitive terminals, Microsoft has made public the assembly-language source for its 6502-targeted BASIC interpreter — a compact, remarkable artifact of early microcomputer engineering that is now available on GitHub under a permissive MIT...
