This board will allow you to switch between two different cartridges without having to remove it from the Atari cartridge port. You will need to cold start the computer after a switch, but if you routinely use only two cartridges, you can save on the repeated insertion/removal process that over time wears down on both of the cartridge and Atari computer edge card contacts. By adding an additional expansion board you can multiply by 2 the number of carts to switch.
