    In 2014, MS-DOS 1.25 and 2.0 were released under a Microsoft shared-source license (Microsoft Research License) which forbids redistribution

    In 2018, both versions were published to GitHub and relicensed as MIT, making them properly open-source

    Today, MS-DOS 4.00 was added to that repo, also under MIT.
