2.5 Unused ROM Locations
Any location in the ROM memory map that is not specified in the user supplied S-record will be factory
programmed to an $83, which is an SWI opcode. The user should provide an interrupt service routine
address at the SWI interrupt vector ($FFFC/D) that points to an appropriate error routine.
