Charles Babbage's Difference Engine and other historic computers

Photos of the Babbage Difference Engine, CDC 160A, Cray Y-MP and other historic computers on exhibit at the Computer History Museum.

Charles Babbage designed the first automatic computing engines, but none of his creations was ever fully built.

In 2002, London's Science Museum completed the first fully-functional Difference Engine. A duplicate machine was constructed for Nathan Myhrvold, tech millionaire and former chief technology officer at Microsoft. That second machine is on display at the Computer History Museum in Mountain View, CA.
