BetaNews: Microsoft re-open-sources early versions of MS-DOS on GitHub

BetaNews: Microsoft re-open-sources early versions of MS-DOS on GitHub. “Back in 2014, Microsoft gave the source code for MS-DOS 1.25 and MS-DOS 2.0 to the Computer History Museum. Now — in a move it describes as ‘re-open-sourcing’ — the company has pushed the code to GitHub for all to see.” I am feeling old and creaky.
