Visited the National Museum of Computing today. I've been to plenty of computer museums – but this one is special: Almost everything works!
You can type on an Enigma, and then see how a bombe helped decipher it. It's *loud*!!
They also have a computer from 1951, the "Witch", which still works! It had 340 bytes of RAM, could calculate five values per second, and punch them out on paper tape!
