The National Museum of Computing at Bletchley Park houses a unique collection of computers. Our expert team have maintained, restored and rebuilt some of the most important systems in Britain's business, war-time and personal computing history.

You can't see our amazing collection during Covid-19, but you can speak to the experts who'd usually be on hand in our galleries as TNMOC is running a series of online video Q&As.
