True Art.  But if that rom has been replaced, is not the old grey ghost 
then functionally a coco2? Minor hardware diffs of course, like the 
slower speed of the op-amp in the bit-banger, but will this code be able 
to tell the diff and mis-behave?  How the game plays is of course the 
final answer.

If the roms have been replaced, methinks the label lies. :)
