On August 4, 1997 I toured the American Computer Museum in Bozeman, Montana. Watched a short movie on the evolution of the computer that was very good, then got private tour of the museum. Since by visit they have changed their name to American Computer & Robotics Museum. It is the World’s Oldest Continually Operating Museum of its Kind.
Founded in May of 1990 by visionary collector George Keremedjiev, the American Computer & Robotics Museum's mission is "To collect, preserve, interpret, and display the artifacts and history of the information age."
The exhibits span 4,000 years of human history, from original cuneiform tablets to the first personal computers, and include topics such as Artificial Intelligence, Quantum Computing, the Space Race, Cracking the Enigma Code, and more.
This is a VERY GOOD museum that you should visit if you are ever in the Bozeman area. It has very good and complete displays from the beginning up to today including some original stuff related to the development of the microprocessor. Lots of new and updated exhibits since I visited in 1997.
They have been visited by and have autographed pictures of the scientist/engineers who invented much of the technology. Very interesting.
