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.

In 1980, IBM approached Microsoft to work on a project code-named “Chess.” What followed was a significant milestone in the history of the personal computer. Microsoft, at the time, provided the BASIC language interpreter for IBM. However, they had other plans and asked Microsoft to create an operating system. Without their own on hand, Microsoft licensed an operating system from Seattle Computer Products which would become the foundation for PC-DOS and MS-DOS.

IBM and Microsoft developed a unique relationship that paved the way for advancements in the nascent personal computer industry, and subsequent advancements in personal computing.

Bill Gates was interviewed by David Bunnell just after the launch of the IBM PC in the early 1980s for PC Magazine’s inaugural issue, and provided the backstory: “For more than a year, 35 of Microsoft's staff of 100 worked fulltime (and plenty of overtime) on the IBM project. Bulky packages containing computer gear and other goodies were air-expressed almost daily between the Boca Raton [IBM] laboratory and Seattle [Microsoft]. An electronic message system was established and there was almost always someone flying the arduous 4,000 mile commute.”
