Open sourcing MS-DOS 4.0
Open sourcing MS-DOS 4.0
In partnership with IBM, Microsoft is releasing the source code to MS-DOS 4.00 under the MIT license. Learn more.
Opensource windows, you cowards. You love opensource, don't you?
MS chose the MIT license which is entirely free software.
I doubt adding a "no commercial" clause prevents the big tech companies from training their AIs on your material. They currently claim it's fair use to take any copyrighted content, regardless of the licensing.
They mention the Computer History Museum. The version control history would also be interesting, from a historic and software development industry history. Whatever they may or may not have used back then. Of course publishing that is likely much less viable and possible due to different concerns.
I think this is a good opportunity to mention FreeDOS for those interested: https://freedos.org/
I want MSDOS 6.22, Windows for Workgroups 3.11 and Windows 95. And classic MacOS would be nice.
