MS-DOS, Source public available on March 25 2014 with MS Research License, released with as Free Software MIT license in 2018, this yer released as Open Source MS-DOS 4.0.
Anyway, the Source code was available since 2014, only different licenses since then.
So cool, thanks. As a kid I spent so much time in DEBUG, stepping through DOS's executables, and especially the Interrupt handlers. It's so neat to see the actual source code-- way easier to read and follow. I didn't know it was all written in assembly, from within Debug it sometimes seemed so messy and convoluted that I just assumed more was written in C.
Is this useful for hobbyists besides poking around and seeking the design philosophy at work back then?
Like would there be any advantage or reason to implement this in a home project? For example maybe that it's lightweight and has some rare compatibility or anything like that?
