A Turing Machine: The Hardware

Sean pointed me to a video (abvoe) explaining the working of a real Turing Machine built by Mike Davey in Wisconsin. It is worth noting that Turing didn’t (to my knowledge) every try to make the machine he described for theoretical purposes. Also worth noting (as is clear in the video) is that there are actually 3 settings for each position: nothing, 0 or 1.
