Sardis Technologies ST-2900 NitrOS-9/6809 Level 1 Package

(This page is still under construction.)

NitrOS-9 is a very powerful multi-user, multi-tasking operating system, yet easily runs on a 64KB ST-2900. NitrOS-9 was derived from the Microware OS-9/6809 operating system that was created in 1979. While Microware no longer supports OS-9/6809, NitrOS-9 is currently in active development, and is free and open source software.

The ST-2900 NitrOS-9/6809 Level 1 Package includes a disk image for a boot disk that is already pre-configured for the ST-2900. The ST-2900 version is being added to the NitrOS-9 build system. Also, each module is supplied on our disk as a separate binary file, with source code, to make it easy to customize the OS9Kernel and OS9Boot files.

NitrOS-9/6809 was initially ported to the ST-2900 in 2019-June.

ST-2900 NitrOS-9/6809 Level 1 Package features:

• device drivers and device descriptors for ST-2900 peripherals
• easily create customized, configured, bootable ST-2900 system disks
• floppy disk driver and format program based on licensed version of SDisk from D.P. Johnson
