Analytical Engine
     
         A design for a general-purpose digital computer
        proposed by {Charles Babbage} in 1837 as a successor to his
        earlier special-purpose {Difference Engine}.
     
        The Analytical Engine was to be built from brass gears powered
        by steam with input given on {punched cards}.  Babbage could
        never secure enough funding to build it, and so it was, and
        never has been, constructed.
