John hasn't completed a profile. Should we look for some other people?

John Graham-Cumming: The greatest machine that never was
Please stop repeating that. You are simply incorrect. As I said below, and in the talk itself, the machine in the CHM and in the Science Museum in London is the Difference Engine No. 2 (http://en.wikipedia.org/wiki/Difference_engine). It's a very interesting calculator designed by Babbage, but IT IS NOT the Analytical Engine and IT IS NOT a computer. The machine we are proposing to build is the Analytical Engine: http://en.wikipedia.org/wiki/Analytical_Engine

The machine in the Computer History Museum is the same as the machine in The Science Museum. They are both the Difference Engine No. 2 designed by Babbage. Neither is a computer (both are specialized calculators) and are not programmable. The Analytical Engine (that I was talking about) is a true computer programmable with punched cards. There isn't one yet in existence anywhere.
