Video Games and Saabs? Why not :)
An Easter egg is an intentional inside joke, hidden message, or feature in a work such as a computer program, puzzle, music, video game… One of the oldest and most popular games is certainly Pong (Highball).
Not many people know you can play Pong in a Saab or more precisely on the Tech II! — the game is included as an ‘Easter egg‘ in the car’s on-board computer. When using the GM Tech II on a Saab 9-3 SS if you go into the Airbag/SRS system submenu, there is a easter egg that allows the tech to play Pong on the Tech II.
Now We all know why they charge an hour labor for Tech II sessions :)
