Analytical Engine Analytical Machine <history> 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. (http://fourmilab.ch/babbage/). (1998-10-19)
