For DOS versions 1.25 and 2.0, Microsoft has publicly released both the compiled binaries (COM and EXE files), as well as the source code, on their official Github account. You can download them here.

The question is: Why M$ never released MS-DOS 6 or Windows 3.1 sources? (and never will!)

Just checked that GitHub again and found they now have DOS 4.0 and DOS 4.0-ozzie (I don't know what the ozzie version even is). They seemed to skip all of DOS 3.x versions though.
