MS-DOS v1.25, v2.0, v4.0 Source Code

This repo contains the original source-code and compiled binaries for MS-DOS v1.25 and MS-DOS v2.0, plus the source-code for MS-DOS v4.00 jointly developed by IBM and Microsoft.

The MS-DOS v1.25 and v2.0 files were originally shared at the Computer History Museum on March 25th, 2014 and are being (re)published in this repo to make them easier to find, reference-to in external writing and works, and to allow exploration and experimentation for those interested in early PC Operating Systems.

What is this?The original source code of MS-DOS v1.25, v2.0, and v4.00, published by Microsoft for reference. The v1.25 and v2.0 parts include compiled binaries too, and v4.00 was jointly developed by IBM and Microsoft.
Is this an operating system I can run, or just source code to read?Neither — it is a frozen historical archive rather than a maintained product. The source files are kept static, and the repo offers no build scripts or instructions for running anything.
How do I get the code and explore it?There is nothing to install: fork or clone the repo and browse the v1.25, v2.0, and v4.0 source trees. It is meant for exploration and experimentation with early PC operating system code.
Do I need any toolchain or build environment for it?None — the repo is just source files and binaries, with no build scripts, package manifests, or declared dependencies.
Can I submit fixes or improvements?You cannot improve it in place: the repo is archived and kept static, so modification pull requests are declined. The intended path is to fork it and experiment on your own.
Where did this code come from originally?Microsoft first shared the v1.25 and v2.0 files at the Computer History Museum on March 25th, 2014, and republished them in this repo so they are easier to find and cite. The v4.00 source came out of a joint IBM-Microsoft effort.
Can I use the MS-DOS name or Microsoft logos in my fork?Only within Microsoft's Trademark & Brand Guidelines — use must not cause confusion or imply Microsoft sponsorship. Any third-party trademarks follow their own owners' policies.
