===== Operating Systems =====

An excellent source for vintage DOS operating systems is the [[https://winworldpc.com/library/operating-systems|WinWorld Library]].

I have run MSDOS 5.0, MSDOS 6.22, PCDOS 2000 (7.0). I know of others who have had success with FreeDOS, also.

NOTE: PCDOS comes with the E.EXE editor, which is the first WYSIWYG editor which runs on the VGA3.
