Bertie the Brain
Description
Bertie the Brain is an early computer game of Tic-Tac-Toe. Built for the 1950 Canadian National Exhibition, the game allowed players to play against an AI opponent. Player input was given using a lit keypad and the state of the game displayed on panels lit by light bulbs rather than a conventional screen. An additional panel with light bulbs would show whether the player or AI was on a turn. The difficulty of the AI could be adjusted by the operator.
Bertie the Brain was created to demonstrate the additron tube, which was soon surpassed by the transistor.
