Abstract
The present invention provides a computer system supporting multiple, removable ROM-based applications without requiring the ROM-applications to be inserted into a particular slot. The computer system accepts one or more cartridges into any combination of slots. Once a cartridge is inserted into a slot, the computer system senses the insertion of a cartridge. The computer system then determines whether to swap the address ranges associated with the cartridge connectors, or slots. The address swap is implemented by either (i) swapping the cartridge connector chip selects or (ii) performing a page swap with the memory management unit.
