    The Difference Engine

    The Difference/Analytical Engine was invented by Charles Babbage in the early 1900's. It used a system of wheels, pulleys, gears, and poles to calculate mathematical problems. It was never really finished and has only been done to prove that it works. It has all the traits of a computer except for electrical. Charles Babbage
