Apple accelerated the Apple II twice--once in the IIc+ with a Zip Chip clone design, and once in the IIgs with shadow RAM. Preserving the compatibility that makes a hack interesting imposes many constraints that keep it from being simple.
I'm curious if anyone has tried to copy the IIc+ zip chip design...since there were a few discrete components perhaps this would be a possibility? I know there was a PLA or something, is there a way to read the one in the IIc+ to copy it? (I know some are copy protected.)
