+This repo contains the original source-code and compiled binaries for MS-DOS v1.25 (June 198) and MS-DOS v2.0 (March 1983).
 
 These are the same files [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.
