Microsoft Open Sources MS-DOS 4.0
Scott Hanselman and Jeff Wilcox, on Microsoft’s Open Source Blog:
Ten years ago, Microsoft released the source for MS-DOS 1.25 and
2.0 to the Computer History Museum, and then later republished
them for reference purposes. This code holds an important place in
history and is a fascinating read of an operating system that was
written entirely in 8086 assembly code nearly 45 years ago.
Today, in partnership with IBM and in the spirit of open
innovation, we’re releasing the source code to MS-DOS 4.00 under
the MIT license. There’s a somewhat complex and fascinating
history behind the 4.0 versions of DOS, as Microsoft partnered
with IBM for portions of the code but also created a branch of DOS
called Multitasking DOS that did not see a wide release.
I am reminded once again that I somehow managed to get a computer science degree despite being utterly baffled by assembly code.
