In April Microsoft open sourced the source code for MS-DOS 4.0, making it available on GitHub under the MIT license. https://cloudblogs.microsoft.com/opensource/2024/04/25/open-sourcing-ms-dos-4-0/ #MicrosoftOpenSource #MSDOS4.0 #SoftwareHistory #softcorpremium

Microsoft releases MS-DOS 4.0 as Open Source Code.. well kinda..?

"Microsoft open-sources infamously weird, RAM-hungry MS-DOS 4.00 release" - Ars technica

#MSDos4 #Rust

Now that MS-DOS 4.0 has been made open source, it probably won't take long until someone rewrites it in Rust.

You folks are funny. #MSDOS4 was universally disliked when it was released, and now, just because the source is available, it’s the new hot shit?

Pitkällisen työn jälkeen muinaisen MS-DOS 4:n lähdekoodit on saatu pelastettua, arkistoitua - ja nyt ne on Microsoftin siunauksella julkaistu avoimena lähdekoodina

MS-DOS 4:een liittyy myös todella mielenkiintoinen kulma ns. "Euroopan MS-DOS 4:n" muodossa. Kyseinen käyttöjärjestelmä oli moniajoa tukeva harvinainen versio MS-DOS 4:sta, joka syntyi IBM:n ja Microsoftin yhteistyönä.

Why do people claim Microsoft “releases” MS-DOS as open source? In the commit history, the first file is the MIT license…

Sure, the commit history can be backdated but the “verified” commits can’t be falsified, and they are genuinely from 2018.

Sure, 4.0 is new, but that’s about the only new thing here. (For some value of new)

I love reading code comments when old software gets open-sourced. #msdos #msdos4

(Found in the PRINT command assembly code of the MS DOS 4.0 source)
