as cheesey as it may be- my favorite was the Turing Machine replica. There were a lot of other notable systems and gadgets(like vintage VR headsets), but seeing the collassal piano-like contraption was visably what stuck out the most. Mind you, its been many years since- but i would highly recommend visiting if given the chance. Walking through it doesn't take that long to do unless you _really_ want to take in the details- which only shows how genuinely interested you are in the history of the subject-matter.
Also fun fact, there used to be a similar museum in my state up called The Computer Museum up until the late nineties when its founders decided CA was a better location for preservation and decided to move their inventory to none other than the Computer History Museum
