Well, you can’t actually meet it, as it’s really heavy and awkward to carry on a train, but feel free to gaze upon it lovingly from afar. From the good people at Fenton Heavy Industries (who brought us such hits as the FIBIAC and Turbo Entabulator), the Numbotron is the latest and greatest in impractical computing. It wasn’t ready in time for 2014’s Interactive Show, but I finally got around to properly documenting it. This electromechanical wonder can emulate Babbage’s Difference Engine with ease – it can even find all the prime numbers under 1000 in less than half a century! Enjoy the full write-up on my site, and if hate yourself, take a shot at writing your own code for the simulator!
