What’s the Difference?

When I wrote about our San Francisco trip, I mentioned that we just missed seeing the Babbage Difference Engine at the Computer History Museum. Well, the full exhibit is now open and I’m even more disappointed we missed it. The museum has a very nice section on their site devoted to the Difference Engine, including a description of how it works and a video of the beautiful beast in operation.

Wired also has an exclusive video of the machine in operation.
