Silicon Valley's Computer History Museum is celebrating its reopening this week with a major exhibit featuring one-of-a-kind artifacts called Revolution: The First 2000 Years of Computing.
Among the key exhibits currently on display is Difference Engine No. 2, built using the original drawings for the first automatic computing engine by Charles Baggage 153 years ago. The Revolution exhibit also has an online display.
Apple co-founder Steve Wozniak is featured in a video promoting the grand reopening.
