Hi Bill, Two suggestions: Check out Evan Koblentz's list of museums: http://www.snarc.net/c-places.php Also, There's a pretty cool Historical Electronics Museum near Baltimore-Washington International Airport that has a broad range of gear and exhibits: www.hem-usa.org . You can see on their site, that many of the exhibits are Defense-related. They have different areas: Fundamentals Gallery Communications Gallery Early Radar Gallery Cold War Radar Gallery Modern Radar Gallery Countermeasures Gallery Under Seas Gallery Electro-optical Gallery Space Sensor Gallery My kids love it. We also use their facility for our yearly Robot Fest. Nice folks to work with. Scott -------------------- I've heard that the Computer History Museum in Mountain View CA is a good one. Any comments? If one had to choose only one (pre-PC) computer history museum to visit in the US, would that be the one to choose? Please provide leads to any other good computer museums in the US that have good hardware collections. I'm interested in pre-PC computer history only. The history of IC technology development also interests me and I'd enjoy hearing about any US museums/exhibits which focus on that topic. Thanks, Bill --------------------------------- Relax. Yahoo!
