Someone needs to either calculate (theoretically) or profile 
(experimentally) what sort of bandwidth you get sucking off an IDE on the 
Coco... I'm pretty sure the solution will be CPU bound - reading from the 
disk data register and blatting into video memory - so you're down to the 
sub-1MBps already. At 2bbp, 320x200x60Hz is 2Mbps...
