No, but OS-9 ones would.  Unless I am the only one who runs more than
one simultaneous process under OS-9.

In the graphics cartridge.  Dedicated to the graphics.  Doesn't take
away from the memory availabel to the processor.

No, actually the COCO CPU does less as it doesn't have to compute
things like graphics vectors.  Graphics processor in the cartridges
does that freeing up the COOC CPU to do more of the things it does

OK, I have said my piece.  Obviously my interests as far as the
COCO go are considerably different from the mainstream.
