Looking at the Excel with the truth table, it is evident that nVIC and nCIA are driven in the VIC address space where it does not make any sense. Maybe it's some kind of error the designers made, and nobody noticed (or nobody bothered)? > What drives A15,A14 during such accesses, anyway? Good question. I can't see anything in the schematic that could drive them. Maybe that's not very relevant, since the VIC memory map seems to repeat itself every 16 kB. Regards, Michau.
