Before the Commodore 64 appeared on the market, there was the Think-A-Tron, the first computer toy. It is not like any computer that you see today. There was no mouse or big screen or Cat5e Keystone jack. This computer ran on two “D” batteries and came with punched cards which had questions on it that you wanted answered. After feeding the card into the computer, the answer would appear on the screen. There were even flashing lights. The toy retailed for only $10 in 1967 and you can still find them at auction sites for $30-$50.
