Default Apple-1 with Baffatari Boards setup

You can load atari 2600 games from a cartridge using only the socket, CPU and Atari boards. To be able to use the complete "Atari 2600 Setup" (Apple-1 with Atari 2600), it is necessary to use the Atari 2600 Pages board that allows you to turn off the rom board and configure the memory board to access and run a game from it. To make this possible, connect the "Atari 2600 Pages" board to Rom, Ram and Atari boards and select the jumpers according to the settings below.
