Atari 7800 cart types In the process of researching 7800 carts I discovered that there a quite a few vairations of the carts. This list documents what I found in the cartridges I have, but it's possible that some carts may have been made in more then one type. The type numbers below are totally arbitrary and have no special significance. Each cart in the list lists the name, type, ROM chip part number, and jumper setting. Type 1: Standard ROM cart.
