Cool Retrotech

Via Isegoria, here is Charles Babbage’s Difference Engine–in high-resolution photography and with a video showing the machine at work. It was designed in 1849 but not actually built until 2002.

The Difference Engine is not a general-purpose computer, but rather was designed for the specific purpose of producing mathematical tables by the method of differences. More about Babbage, the Engine, and the Method of Differences, here.
