+1 this commenter. I just visited the UK for the first time at the beginning of this month and had a fantastic ~3 hours at Bletchley Park, but felt I had to cram TNMOC and the amazing Colossus live demonstration (where I asked a million questions) and everything else in the museum in the 90 minutes I was there. If I assume other HN readers are like me, I would dedicate at least 2.5-3 hours for TNMOC to actually get a chance to actually see and play around with their extensive collection of vintage machines.
