Microsoft has republished the source code of MS-DOS 1.1 and 2.0 on September 22, 2018 on
GitHub under a more permissive license (MIT).
This event comes a few months after the release of source code of the famous file explorer
Winfile in April under a free software license (MIT again).
Could this be the sign of the beginning of the release of the source code of the old historical software by Microsoft?
This would be great for the retro-computing community and for various open-source projects (like FreeDOS).
