86-DOS 0.3

86-DOS 0.3 was a release of QDOS/86-DOS. Because of the fact versions 0.33 and 0.34 are sometimes mislabeled 0.3, even by Tim Paterson himself, this release's sources are limited. The only correctly labeled source is the Microsoft license agreement.

Mislabeled Sources

 * 86-DOS Version 0.3 User's Manual/Programmer's Manual
 * "0.3" is referring to either version 0.33 or 0.34.
 * "A Short History of MS-DOS" by Tim Paterson
 * "0.3" is referring to version 0.34.

Correctly Labeled Sources
There is only one source mentioning 0.3 that is correct - the 6 January 1981 license agreement between Microsoft and Seattle Computer Products, which mentions a sole instruction manual versioned "0.3". The license agreement states that the manual is dated 15 November 1980. Because 86-DOS 0.33 - the next version - was released in December 1980, the version number cannot be a mislabel.
