MS-DOS Is Going To Be Open Source

The MS-DOS is used for more than 30 years. During this period, the Windows operating system grew much and become a convenient platform with the graphic interface, but we still know MS-DOS and some people even use it. All these years, the source code of MS-DOS was not shown to the public but Microsoft is going to make this system open source for now.

The Microsoft company is publishing the source code of MS-DOS under the MIT license. Developers can download its code, modify it and use as they want. It is a great opportunity for developers who worked with this system in the 80’s and now want to read its code or experiment with it.

In the package, developers get the access to the all source code of 1.25 and 2.0 versions, the December 1980 release, and other versions. It also contains the documentation in txt and doc files. People who are already familiar with this code say that it is very interesting to read the documentation of source files, object files, and comments in the source code.

The code is published on GitHub so any developer can read it there. However, you will not be able to pull the repository because pull requests will be blocked and the Microsoft company decided not to make changes into this code.
