Please sponsor a valve on Colossus to show your support for The National Museum of Computing at Bletchley Park. Colossus was the world’s first electronic programmable computer and was used to crack the Lorenz codes of German High Command during World War II. There were 12 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.
