Well…unless you mess with the MinPty or MaxAge (which are OS-9/68000
knobs, not existing in OS-9/6809), the difference is that all the processes
(that aren't asleep waiting for I/O or of their own volition) will get
*some* of the CPU time, rather than none. If they're of lower priority,
they get less of it than higher priority processes, of course.
(MinPty and MaxAge? No process with priority < MinPty gets CPU time until
all processes with priority >= MinPty are sleeping; no process priority
gets to age above MaxAge. Process priorities are aged when they don't get
to execute, so that the scheduling is fair.)
