Take a look.

It's from a book titled, "Late Night with David Letterman: The Book." This used to be one of those TV cards whenever the show would go on break or back to the program.

To the right, you know what that is. But the guy playing at the Robotron cabinet disguised as the show's title is playing some sort of "game" maybe an Atari 8-bit or just some mock-up. Anyone know if this "game" is a real or not?
