The Atari Flashback is a game system that includes 40 original Atari 2600 games for about $30. The games are placed on a rom chip just like the original except it is soldered inside the case instead of on a cartridge. You can bypass the rom chip with a couple toggle switches and add an external cartridge adapter to play any of the original 2600 games. All of the pinouts are marked on board and the site has links to get the proper connector. Time to start hitting up ebay for the big game lots.
