2024-03-02: The wiki ran out of disk space, so things were not working. This has been resolved by adding another 5GB of quota ;-) Thanks to Tim Lindner for reporting the issues. 2020-05-17: If a page gives you an error about some revision not being found, just EDIT the page and the old page should appear in the editor. If it does, just SAVE that and the page should be restored. OS-9 Al (talk) 12:22, 17 May 2020 (CDT)

Home / Software - NitrOS-9

The history of NitrOS-9 is an interesting one, taking several twists and turns to its present incarnation.

NitrOS-9 was primarily a creation of three Canadians: Bill Noble, Wes Gayle and Curtis Boyle, starting out as an enhanced version of OS-9 Level Two for the Color Computer 3. It came into existence for one driving reason: to incorporate the then-newly discovered 6309 instructions into OS-9 Level Two.

In its first 6 years of life, NitrOS-9 was sold through various companies, including Northern Xposure and Farna Systems. Into the late 1990s, Alan DeKok took over NitrOS-9 and further enhanced it, fixing bugs and adding new features.

Additional work by Alan and Boisy Pitre over the course of the next few years yielded a revamped NitrOS-9. This "re-released" version became an open source project in 2003, and now supports all Color Computers, including the Dragon 64.
