Just a simple $100-$1ff memory test and then a jump to ($8000), where the cartridge would also be mapped? I guess the cartridge will then complain about the KERNAL and BASIC ROMs and any RAM above $1000, as they are not available in the UltiMax configuration. There are 1014 $aa bytes at the end of the 8k ROM, which is pretty much space for additions. Marko Message was sent through the cbm-hackers mailing list
