86-DOS 0.30 is an unreleased beta[1] build of 86-DOS. Not much is known about the build besides its existence.
Because of the fact versions 0.33 and 0.34 are often referred to as 0.3, even by Tim Paterson himself, this release's sources are limited. The only known correctly labeled source is a 1981 license agreement between Microsoft and Seattle Computer Products.[2]
Authenticity of sources[edit | edit source]
Mislabeled sources[edit | edit source]
- 86-DOS Version 0.3 User's Manual/Programmer's Manual by Tim Paterson[3]
- "0.3" is referring to either version 0.33 or 0.34.
- "A Short History of MS-DOS" by Tim Paterson[4]
- "0.3" is referring to version 0.34.
- comp.os.cpm message by Barry Watzman[5]
- "0.3" is referring to either version 0.33 or 0.34.[6]
Correctly labeled sources[edit | edit source]
There is only one source mentioning 0.30 that is known to be correct – the 6 January 1981 license agreement between Microsoft and Seattle Computer Products, which mentions a sole instruction manual versioned "0.3".[a] The license agreement states that the manual is dated 15 November 1980.[2] Because 86-DOS 0.33 – the next version – was released in December 1980,[7] the version number cannot be a mislabel.
A second source that may be correct is an email between Tim Paterson and comp.os.cpm newsgroup member Bill Hemmings. In the email, Paterson refers to version "0.3" of 86-DOS, saying it was only seen by 30 people.[1] It is unknown whether this is a mislabel or not.
Notes[edit | edit source]
- ↑ This manual is not the same as the scanned manuals also versioned "0.3", as instead of having a "user's" manual it has an "instruction" manual. Additionally, the scanned manuals are from "[circa] December 1980".
