Terminator: The Sarah Connor Chronicles Easter Egg - The Computers Know the Truth

In the scene where Cameron goes to the chess computer tournament, one of the "dumb AIs" notices her, and waves (it is the humanised looking torso with a face and arm). When she looks down at the screen which shows a highlighted area around her face. At the bottom of the box are the faint numbers "101". A reference to the T-101, the "original" Terminator, played by Arnie in the first movie.
