MS-DOS v1.25 and v2.0 Source Code

This repo contains the original source-code and compiled binaries for MS-DOS v1.25 and MS-DOS v2.0.

These are the same files 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.
