Silver and Gold - Charles Babbage's Difference Engine

This is a view shows the intricate workings of the backside of the famous Charles Babbage Difference engine. Charles Babbage (1791-1871), computer pioneer, designed the first automatic computing engines. He invented the earliest of computers but failed to build them. The first complete Babbage Engine was completed in London in 2002, 153 years after it was designed. Difference Engine No. 2, built faithfully to the original drawings, consists of 8,000 parts, weighs five tons, and measures 11 feet long. This example was seen in the Computer History Museum in San Jose. More information on this brilliant machine can be found here - www.computerhistory.org/babbage/ - It's certainly worth learning a bit more about!
