Maybe that is > used instead of a real decoder in the MAX/UltiMAX basic cartridge? IO2 doesn't exist at all on the Ultimax, IIRC it's used for a cia shift register pin. IO1 seems to be the same $DE00 select on the Ultimax and C64, you could put RAM there but it's a bit out of the way. I'd like to see a Max basic cartridge, but I'm guessing that it used it's own decoding. It's super trivial to and/or a few lines together.Received on 2018-05-04 12:00:03
