I am a senior living in the heart of Silicon Valley. As an engineer, I even worked at the company that started Silicon Valley Fairchild Semiconductor and lived and know much of the history, So I was quite impressed by both the docent tour and the thoughtful and fascinating museum. There was a fluid and fascinating order to every aspect of computing history from ancient times to the present day. More impressive, the nontechnical people in group such as my wife, son, and daughter-in-law enjoyed the tour more as than us techie types. The tour and exhibits allowed the nontechnical to learn and understand in a unintimidating fun environment. You can spend easily 2-4 hours learning about all aspects computing history including using an Abacus , old mechancal,and electical calculators, analog computers,video games. Lot of interactive displays to make life interesting including Pong.. Good for all ages. My biggest regret for a first time visit is I missed the daily 1:15p.m. mechanical cranking and use of the Babbage machine which should be on everyone's bucket list. Will definitely take out of town guests to this museum.
