Talk:Bill Gates

DOS source code

From the current version of the article:

"He started Microsoft, after reportedly cutting open source code from UNIX down to a basic Disk Output System (DOS) and making it proprietary.[citation needed] MS-DOS."

I think that is, or was, matter of (specialized) debate. Some analysis showed that it is not a copy over. Can't think of the article that I was reading but if I remember correct the person that looked at it made some effort to get the source code for evaluation and those parts that are identical to some degree, are above suspicion. Any ideas? - Sunvalley (talk) 21:26, 1 June 2020 (UTC)

"PC DOS version 1.0, which supported only floppy disks, was shipped when IBM first released their PC in August 1981. Microsoft then substantially rewrote the software to support subdirectories and hard disks; version 2.0 was released with the IBM PC-XT" in March of 1983." source; https://computerhistory.org/blog/microsoft-ms-dos-early-source-code/
