A SAGE operator's terminal — A SAGE (Semi-Automatic Ground Environment) terminal used during cold war to analyze radar data in real time to target Soviet bombers. The light pen, which was shaped similar to a handheld power drill or gun, is resting on the console. Notice the built-in cigarette lighter and the ashtray just left of the light pen. Located at the Computer History Museum in Mountain View, California.
