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.
看到上面一位朋友的两个评论，我有一些感想：那个年代的软件工程规模与现在的软件工程规模根本不能比较，每个时代都有属于自己的特点，每个时代都有属于自己的困难。Linus Torvalds的父亲曾经说过一段话（Nils Torvalds非常谦虚）：“...For that reason I think it was very important for Linus to enter the computer world when computers still were simple enough even for a 10-12 year old boy to understand what was inside this machine.”我觉得非常有道理。
