I'd say it's an embeddable OS. On the Coco it's not running embedded. If
you put it on some device that has a computer in it, but isn't a desktop
machine like the Coco, then it would be an embedded os. I've definitely
seen it used in embedded systems. By similar logic, is Linux an embedded
OS? No. Is it embeddable? Yes.

OS-9 is not a RTOS. When your thread is running in an RTOS you can
schedule your thread so that it is guaranteed to run, say every n msec.
IIRC, the scheduler in OS-9 is fair, within its priority scheme, but
provides no guarantees.
