The Deutsches Museum in Munich is the world's largest and IMHO best museum of science and technology. Especially the mechanical engineering, cars and airplane departments are one of its kind.
Though, the computer history department is a bit too small and similar in size as the equivalent Science Museum in London. In both you find a Cray super computer, first Zuse computers and many older mainframes and terminals, etc. But everything is death, every historical computer sits just there. There is no interactivity, what a shame. They should at least re-work a Cray 1 or 2 super computer and let visitors play around on its terminal - that would be awesome.
