What is this atari accessory?

[Slate]

I bought a switchbox for the Atari 2600 recently. It allows you to plug in 6 games at a time, But you still have to turn the system off then push a button to switch games. It also has storage for two games, And has a sticker on the bottom that says "Rga International Limited". What it this accessory called?

It's the 'Video Game Brain'.

I've got one of those. They're designed to let you connect 6 cartridges to your machine without all the wear and tear of removing and inserting carts in your console. Little did they know back then that Atari built the 2600 like a freakin' tank and wouldn't need such a thing.

I've seen them at game conventions new in the box for something like $30, but I never felt the need to get one. Then I managed to get one at a flea market with a Sears Heavy-Sixer for $10. Interesting little gadget, but I never bother using mine.
