Also, if you don't mind traveling a bit further, there's the Moffett Field Museum (http://www.moffettfieldmuseum.org/), Intel Museum (http://www.intel.com/content/www/us/en/history/museum-visiti...), and a bit further south is the San Jose tech museum (http://www.thetech.org/).

If you have a car, it might also be worth going to Stanford's campus -- just take a walk anywhere.

Book lots of time for this place if you go. I was there for two hours last time, and that wasn't enough to really see everything I wanted.

I was there for a day and when the museum was about to close I realized I hadn't properly experienced the half of it and came back the next day to spend another day there. Hands down the best museum I've ever seen.

Among the things there are original Google servers, Apollo computers, Apple I, Lisa and a hundred more things I can barely remember that make me want to visit it for another two days just to refresh my memory.

+1 to this, the computer history museum is truly awesome.
