Built in 1958, it was "gynormous." "In addition to the oscilloscope screen and the controller, the guts of the original game were contained in an analog computer, which is "about as big as a microwave oven." "We have to load it into the back of a station wagon to move it. It's not a Game Boy that you put in your pocket."
