Before deciding to visit this museum, rank yourself on a scale of geekdom from 1 to 10.
If your initial reaction is, "Do you mean binary or base-10?" then this is the place for you.
As a museum, it's still evolving and that's somewhat fascinating in and of itself. Thanks to the fall of SGI as a computing superpower, the non-profit that operates the Computer History Museum was able to purchase a beautiful building that SGI used exclusively for wooing clients (ah, to be in 1997 again...). Needless to say, once SGI no longer had anything meaningful to sell to clients, they ditched the smoke and mirrors, and the Computer History Museum and the rest of us in the Bay Area can reap the benefits. As far as I can tell, they kept everything in the building including the color scheme. It's surely no accident that the museum seems to be built around the color purple, and even the "visible storage" exhibit is built using old cubicle walls. That's the kind of DIY spirit that I'm proud to say still seems to be around today, and is especially evident in the exhibits at the museum.
They have a couple of bona-fide exhibits, which they're testing the waters on; but the real meat is the "visible storage" a.k.a. "the coolest garage ever". It's loosely organized chronologically and by topic, and has actual specimens from the history of computing from the 1600s to today (go abacus!). If you're a techie you'll no doubt be at once astounded and dismayed that several things you have boxed up in your closet are on display as part of the "history of computing". Atari 800 anyone? Wow, I'm old.
But not as old as some of the computers on display. For certain the best parts of the museum are the ginormous 50's and 60's era computers that are about 1000 times the size of my Palm pilot but had probably 1000'th the computing power. When you see the care that was put into a lot of the older machines' design you soon realize that Steve Jobs was not the first to marry form with function. Be sure to see the "Johnniac", which is part computer, part 60's art-deco piece, and the old military defense computer that's fitted with a cigarette lighter and ashtray built into the console.
Word of caution - leave the computer-phobes at home and geek out on your own. I easily, easily, easily spent the full 3 hours that they were open on a Sunday looking at everything. They have a few impromptu tours that just go through and give back-story to the equipment in the big "visible storage" center, and then there's currently an exhibit on computer chess, bay area innovations, and the gigantic room of historical stuff to dive into. The museum and its collection are at one time amusing, sobering and inspiring. read more
