I can't access my C128 right now, but aren't the MMU registers only mapped at $d500-d51f or some such; the rest of the $d500-$d5ff area reads $ff and is ignored on writes, if I remember correctly. Thus, you could wire something e.g. at $d580 without interfering with anything. Marko Message was sent through the cbm-hackers mailing list
