In 1960, Hasbro unleashed its first personal “computer” to the masses. Called Think-a-Tron, it was launched decades ahead of IMSAI, Apple, or Commodore machines.
Ok, my opening paragraph for this Instructable is just a “bit” overstated, but so was the marketing for Think-a-Tron, “the machine that thinks like a man”. While some toys of the same era, like the Digi-Comp I for instance, endeavored to teach people about computers, Think-a-Tron took advantage of the growing interest in computers to sell a cleverly packaged trivia game. In fact, if there is any “claim to fame” attached to Think-a-Tron, it’s that it introduced the trivia game concept 21 or more years before Trivial Pursuit.

My goal for this project was to honor Think-a-Tron, not to reproduce it. I wanted to build something that is clearly a Think-a-Tron derivative, but utilizes modern fabrication techniques and components. At the same time I would try to maintain the 60s mainframe vibe of the original. As always I wanted to have some fun along the way.
