The National Museum of Computing is dedicated to showing the development of computing in its broadest sense from the pioneering war time efforts that resulted in Colossus, to the products and systems we use today. The museum is part of the whole Bletchley Park experience, and all visitors to the park can visit the museum free of charge when it is open. (A modest entrance fee to TNMOC is to be introduced in the near future.)
TNMOC will be helping us celebrate the 30th anniversary of the BBC Micro, which was released in late ’81. There will be beebs set up for you to try your hand at BASIC programming, and possibly a beeb you can tweet from!
