You mean like one of the GIMIX 6809-based SS-50C bus computers? The
price may be a bit steep for "home" micros, but they've been around for
years, and the memory management does have teeth in it.  OS-9/6809 Level
Two runs quite nicely on them. 

I don't know enough about the GIME chip in the CoCo 3 to be able to say how
protected processes are from one another--they *do* have separate address
spaces, though, and the price is certainly in the "home" computer range.
You might want to pay a visit to someone who owns one and runs OS-9 on it.
