I received the following update on NitrOS-9 today.
Dear NitrOS-9 users and developers,
We have the great pleasure of announcing the availability of the NitrOS-9 V3.3.0 release. NitrOS-9 is an open-source operating system for 6809-based computers (Dragon and TRS-80/Tandy Color Computers in particular), and is compatible with OS-9 from MicroWare.
With the last proper release V3.2.8 being almost 6 years ago, it is more than time to get the numerous new features, bug fixes and other cleanups into the hands of everyone. A version 3.2.9 was close to be released in late 2009 but instead more feature additions, rework and infrastructure changes ensued, and only development versions have been circulating since. The new version has been bumped to 3.3.0 both to avoid confusion with unofficial 3.2.9 builds and to reflect the amount of work going into this release. The V3.3.0 release provides a solid, common base for users, application developers and NitrOS-9 developers to continue work on and develop for their favourite operating system.
Source code and prebuilt disk images can be downloaded from the NitrOS-9 project at SourceForge:
