Please sponsor a valve on Colossus and help create a marvelous new gallery for the world's first modern computer. Colossus was built by Tommy Flowers specifically to help crack the Lorenz codes of German High Command during World War II. There were 10 working Colossi and each had 2,500 valves that performed the code-cracking calculations. A rebuilt and working Colossus is on permanent display at the museum. You can sponsor as many pixels as you like and add your logo or your name or nickname.
