Analytical Engine
Analytical Machine

    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.
