Rich Turner: Microsoft Open-Sources GW-BASIC. In: Microsoft Developer Blogs - Windows Command Line. Microsoft, 21. Mai 2020, abgerufen am 22. Mai 2020 (englisch): „These sources, as clearly stated in the repo’s readme, are the 8088 assembly language sources from 10th Feb 1983, and are being open-sourced for historical reference and educational purposes. … Many have asked if we can also open-source implementations for processors other than the 808x. Alas, we’re unable to provide sources for these ports and/or customizations.“
