Yeah, but wouldn't those help improve compatibility with the Minimig and/or give it a possibility of an AGA upgrade, etc?
The masks for a chip are nothing more than a stack of camera film negative-like things. In order to learn the circuit you'd have to reverse-engineer the stack (probably 20 or 30 masks per chip) together, figure out what the curtiots are and how they connect, etc. all from nothing more than a bunch of IC pictures. That's possible, but it'd be **enormously** tedious. Then it'd help to have an understanding of timing, capacitance, etc. as to why certain things were done. This is basically the most inefficient use of one's time in improving minimig/clonea/etc. Different methods are much better use of one's time and energy. The masks, if they still exist, should be treated only as collectors items to show off to geeky friends and used for absolutely no other purpose whatsoever.
