Microsoft releases ms source code

Microsoft has published the source code of the legendary MS-DOS operating system on GitHub. The new repository contains the original source code and compiled binaries for MS-DOS 1.25 and MS-DOS 2.0. Microsoft is making this move to make the system's source code easier to find, referenced in external writings and work, and to allow exploration and experimentation for those interested in early operating systems.

MS-DOS 1.25 code was created on May 9, 1983

During 2014, Microsoft was part of a collaboration with the Computer History Museum in which they transferred the source code of the system, in addition to the first versions of Word. Now that they're posting it on GitHub, you can reach a much bigger audience.

The MS-DOS 1.25 code was created on May 9, 1983, and is made up of only 7 source files, including the original COMMAND.ASM shell. MS-DOS 2.0 was created on August 3, 1983, and grew considerably in sophistication (and size), being composed of 100.ASM files at that time.

There are some interesting documentation files (.TXT,.DOC) interspersed with the source and object files (many of them deserve to be read, as do many of the source code comments).

All the source code is found in this link, where we can download and start scrutinizing in this system, today considered a relic of computing.

The fact that the source code was published on GitHub does not seem accidental, since Microsoft bought this platform for developers last June for about 7.5 billion dollars.
