Sam, Bill, and Neal are playing Asteroids on Neal's new Atari 2600. The Asteroids shown is not the 2600 version but rather the arcade version. The 2600 version had solid multi-colored asteroids. In the arcade version, the asteroids were made up of lines that outlined the asteroid.
Many of the license plates on the walls in the diner would not exist until years later, some into the 1990s.
Sam's parents give him an Atari 2600 at the end of the episode. In 1980 a new Atari 2600 would not have been a 6 switch version that was shown but a revised new 4 switch version. Also the game shown on the Atari 2600 for Sam was Adventure but it was never an included game pack for the Atari 2600. The original game pack in game was Combat for the 6 switch version and Space Invaders for the 4 switch version.
