The GIME chip is the Coco3 will not support semigraphic modes 
S8, S12, or S24 of the Coco1/2. So if any games or software that 
uses those modes will not necessarily work on a Coco3. 

My guess is that these graphic modes are better done with the 
newer high screen resolution commands that Super Extended Color 
Basic has. 

Yes the Coco3 is only about 99.9% backaward compatible.
