MS-DOS has been Open-Sourced! We Build and Run it!

Microsoft has released the code to MS-DOS on GitHub; Dave takes you a tour of the code, builds it, and runs it on original hardware. For my book on life on the Spectrum: For Clarity on the timeline: - Microsoft licensed (non-exclusively) 86-DOS in Dec 1980 for $25,000 - Paterson left SCP in April 1981 and worked for Microsoft from May 1981 to April 1982. - 86-DOS was purchased outright by Microsoft and renamed to MS-DOS on 27 July 1981 for $50,000 - In March 1982, MarkZ became the dev mgr for MS-DOS 2 The Code: Remember that the code is open-sourced, but trademark law still applies!
