In Western Europe, I can highly recommend Geert Rolf's "House for Retired and Aged Computers"[1] a few kilometres west of Nijmegen, in the Netherlands.<p>It's a private museum focusing mostly on DEC and Sun hardware. Many of the machines run. Geert is a wonderful, enthusiastic and knowledge guide with a trove of DEC lore. Someone needs to sit down with him and record an oral history!<p>[1] <a href="http://www.bejaardecomputers.nl/index-en.html" rel="nofollow">http://www.bejaardecomputers.nl/index-en.html</a>
