Microsoft open-sources a key piece of software history, one that would help the company rule personal computers. //

Having re-open-sourced MS-DOS on GitHub in 2018, Microsoft has now released the source code for GW-BASIC, Microsoft's 1983 BASIC interpreter. //

The sources for Microsoft GW-BASIC are the assembly language for the Intel-designed 8088 microprocessor from February 10, 1983. Microsoft has released the GW-BASIC source code because having open-sourced MS-DOS people wanted it to do the same with Microsoft BASIC.

While becoming open-sourced, Microsoft has posted it on GitHub as an archive and therefore is not accepting any request to modify the source. It's there for historical reference and educational purposes. Also, the source doesn't contain the tools to generate executable binaries.
