SOme possible disadvantages: ... no swapping or paging (Version II
shuffles & relocates using an MMU, but needs bigger 6809 system than Coco).
/* ---------- */

I heartily agree with Mike Knudsen's sentiments about a machine for
teaching OSs, but wish to point out that not swapping or paging is
a disadvantage only in the context of teaching--the decision not to
swap is a MAJOR win for OS-9 over Unix and its clones. (If you can
wait, OS-9/68000 Level III for the 68020 will page...)
