But they disappeared as I browsed the repo. I guess they didn't want that part public?
Edit: I knew I wasn't seeing things! Somebody forked it along with those files: https://github.com/OwnedByWuigi/DOS/tree/main/v4.0
That means Windows XP should be open sourced by ... 2038. Not as far away as it seems. I'll add it to my calendar.
Weird that for a couple minutes, these paths existed: * https://github.com/microsoft/MS-DOS/tree/main/v4.0/bin * https://github.com/microsoft/MS-DOS/tree/main/v4.0/bin/DISK1 * https://github.com/microsoft/MS-DOS/tree/main/v4.0/pdf But they disappeared as I browsed the repo.

Holy cow, this is huge! DOS 1.x and 2.x are too old to run a lot of vintage DOS software, but 4.x would run just about everything.
An interesting thing about DOS is the OS wasn't very involved. Programs did a lot of things we now think of as the realm of an OS, like talking directly to I/O addresses or installing interrupt handlers. I feel like a DOS implementation doesn't even need to do a lot of things, maybe part of why DOS4 is "good enough".
So if MS-DOS 4 was released in 1986, and it is now 2024, that's a 37 year gap between release and open source. That means Windows XP should be open sourced by ... 2038. Not as far away as it seems. I'll add it to my calendar.

4.0 was a buggy release. Where's the DOS 4.01 source?
