I guess as the PETs have at least 40 columns screen wide you donīt need to check that. One problem, though. The start address of a Basic program is different - $0401 for a PET, which is fixed, i.e. the PET _always_ loads to the supplied start address, which makes it fail to load C64 basic progs, that load to $0801. The CBM-II even have a weirder loading scheme. Basic code starts at address $0002 (in a memory bank different from the "standard" bank with zero/stack page. You could check all that with the VICE emulator if you like.
