The following post is from Roy Levin, distinguished engineer and managing director, Microsoft Research Silicon Valley.
On Tuesday, we dusted off the source code for early versions of MS-DOS and Word for Windows. With the help of the Computer History Museum, we are making this code available to the public for the first time.
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.
