If you're ever in Germany and are interested in that stuff, pay a visit to the Arithmeum in Bonn. It's a museum dedicated to the evolution of calculating machines from simple mechanics to current-day computers and they have a vast collection of those machines on display.

While we're talking about German museums, the Deutsches Museum in Munich [0] is ... astounding. They have Konrad Zuse's Z4 electromechanical computer [1] as well as a million other interesting things. Well worth a visit, but allow yourself plenty of time. Like a few days.
