In one episode, Sam and Neil beg their parents for Atari systems. Sam goes to the store with his mom and goes to look at the Ataris. We see some Atari and Intellivision games on the rack. One of the Atari games is in a silver box with a red stripe which didn't come along until later. (The show takes place in 1980.) Also, when they're playing "Asteroid" on Neil's Atari, it's arcade-perfect. As if!

(Note:The store might have had Intellivision systems and games as it came out in 1980.)
