Microsoft releases MS-DOS v1.25 and v2.0 Source Code as Open Source on GitHub

Microsoft has open sourced and posted the source code (MIT License) for MS-DOS 1.25 and 2.0 back from the 1980s.

You can find the code and information on GitHub.

What folks aren’t posting is why this is important. As a survivor of computing in the 80s, I’ll provide my votes:

  1. The history and source of early computing is being preserved and opened up – vintage computing is huge right now and having the materials from that era are vital.
  2. MS-DOS has a checkered history and does things in unorthodox manners at times. Looking at the source code, one can read the comments and see why PC-DOS (for IBM) and MS-DOS (Microsoft) differed.
  3. There are efforts to save computing on old platforms. Some important code only runs on now ancient operating systems. Those system environments must be recreatable to be able to run the important software that was developed specifically for that OS and that era.

Do you believe this is an important step? Post in the comments below.

  1. Maybe we can port MS-DOS to the M4 processor 🙂 But seriously if we can have an interpreted language like Circuit Python on a microcontroller like an M0 or M4 why not Gbasic?

  2. I agree Chris, I’d like to see a decent BASIC running on M0 or M4 hardware also, maybe even save/load from SD card.

Sorry, the comment form is closed at this time.
