[Coco] OS-9 on Raspberry Pi

[L. Curtis Boyle]

Did much software use GWindows? We had that on OS-9000 at work for awhile  It was 3rd party, although I don’t remember who sold it).

It's a very small unit, but is reasonably capable -- should be comparable to running on a CoCo, I suspect a bit faster than that!  Porting to the Pi 3B+ would be more suitable to running a GUI and using it as a modern desktop computer.

Those that write directly to the system and bypass those conventions would take more work. While K-windows compatibility might sound good, it's a dead system. Better to switch to something with more current support, though I haven't seen Xibase9.

Will take time to build a base, but if some of the older OS-9 and OSK programs can be ported, that would speed the transition up. You can download an evaluation copy of Xibase9 that will run on Linux or Windows. Don't know what the limitations are. Downloads - XiSys Software GmbH
