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:
|
|
|
|
* [COMPAQ MS-DOS 2.12](/disks/pcx86/dos/compaq/2.12/)
|
|
|
|
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](http://www.computerhistory.org/atchm/microsoft-ms-dos-early-source-code/),
|
|
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.
