86-DOS 0.3

86-DOS 0.3 is 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 a 1981 license agreement between Microsoft and Seattle Computer Products.

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.
