# 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]( http://www.computerhistory.org/atchm/microsoft-ms-dos-early-source-code/) 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.
