The NitrOS-9 Project provides an OS-9/6809 compatible operating system for TRS-80/Tandy Color Computers and variations of the Dragon Computer.
Runs great in emulation (VCC) and I haven't found a program yet that it can't run. I like how all of the patches and enhancements over the years have been brought under one common code base. Plus now that the source code is licensed GLP, we can all see what is going on "under the hood". Thanks guys. We love you and appreciate all of your hard work.
Long time user of stock OS9 on the Tandy Color Computers, more of a user than a programmer. Recently started using the Level 1 distribution of NitrOS9, have nothing but praise to the development team.
