The Think-a-Tron was introduced by Hasbro in the 1960s as a computer for kids. Dubbed “The Machine That Thinks Like A Man,” this lump of moulded plastic housed a punch-card system. Pick a card that has the multiple-choice question you want answered, feed it to the machine and push the button. The computer starts whirring. Wheels turn, lights flash and within seconds the correct answer appears on the screen.
The Think-A-Tron retailed for around $10 in the sixties and you can still find them on sales and auction sites today for $30-$50.
