We were visiting Bletchley Park and stumbled across the museum. We had to pay £5 for entry but it was so worth it. A step back in time. The staff were welcoming and so enthusiastic about the displays. It is obviously still a work in progress but so good and will no doubt get better.
Highly recommend it if you have worked with computers at all over the last 20 years. You don't have to be knowledgeable about how they work to enjoy the displays.
