It consists of your iPad and a small unit that you plug it into which containing all the games. You then have access to a joystick and buttons for firing at the targets.
Using the 30 pin connector on the iPad, you have access to the 100 Atari games on the app using the controller to play them. They have made the unit small enough to take with you, but that then has some limiting characteristics on the joystick. The games can be downloaded for free at iTunes “Atari’s Greatest Hits”.

You can pick this one up at the Apple Store under the Discovery Bay Atari Arcade for iPad title.
