This is the Atari 5200 Sean Kelly Multi-Cart with Switches. This is from the 90s and I played this alot over the years. Tested again and still works. Very rare to find with the dip switches and had almost the entire catalog, except for a few due to size restrictions. This is rare. Great for playing all the games in 1 cart and for nostalgia's sake too. Any questions, feel free to reach out. Thanks
