Microsoft has released some early versions of MS-DOS and Word for Windows source code to the public. This is nice for those that like to see how DOS looked back in those early days. Definitely something very interesting and fun from Microsoft.
The museum has done an excellent job of curating some of the most significant historical software programs in computing history. As part of this ongoing project, the museum will make available two of the most widely used software programs of the 1980’s, MS DOS 1.1 and 2.0 and Microsoft Word for Windows 1.1a, to help future generations of technologists better understand the roots of personal computing.
