Its mentioned in the readme that they released the sourcecode originally to the computer history museum back in 2014. But now its on github so its easier for the rest of us to look at it. which is supper cool.

Also Macpaint and quick draw was giving to the CHM.

FWIW the source code for 1.25 & 2.0 has been up on Github for probably about 6 or so years now. It was 4.0 that just got uploaded to the repository yesterday.

i'm posting replies everytime i find or think of something new.


I think MS-DOS 4.0 is one of those weird versions where its confusing about WHICH one you are talking about.

wikipedia has some info on this version. (4.0)

I mostly remember MS-DOS 5 and 6. .. i think i found an old computer once that had DOS 3.2
