Microsoft MS-DOS 2.00
There was no MS-DOS 2.00 product per se. Instead, there were OEM releases of MS-DOS based on version 2.00, including:
MS-DOS 2.00 Source Code
On March 25, 2014, the source code upon which OEMs based their MS-DOS 2.x releases was made available to the public by the Computer History Museum, with the permission of Microsoft.
For reasons known only to the Computer History Museum, the precise contents of the five diskettes donated to the
museum remain a mystery. Instead, the museum released a ZIP archive with the contents of the diskettes divided into
two folders, v20object and v20source, with no clear indication which files came from which disk, why some files
were renamed (and what the original names were), and what (if anything) was omitted.
We have divided the contents of the v20object folder into two 320Kb "binary" disk images and the contents of the
v20source folder into six 320Kb "source" disk images, to make it easier to inspect all the files from "virtually" any
PCjs machine.
