Meet Difference Engine No. 2, the first automatic calculating machine, a super computer designed in 1871 by Charles Babbage.
Mr. Babbage never got to build the computer because lack of financing, but in 2002, a London society built it based on Charles' original plans. And the 8,000 parts, 5 tons, 11 foot long machine works like a beauty!
A second machine has been built in 2008, and is currently on display at the Computer History Museum in Mountain View, California.
