Track&Field for Atari 2600 is one of the best conversions from the arcade, and it is a pity that the standard Atari controllers did not provide a compatible gaming experience, that's why Atari included a controller similar to the arcade buttons at the time the game was released. These controllers have been sold separately to be used in systems with compatible joystick ports.
Though these controllers are not considered a rare item they are very easy to build, as the buttons are simply mapped to "Left", "Right" and "Fire".
