SE Peeze Binkhorst sez, “100 years ago today, Alan Turing was born. To celebrate, I wrote a Universal Turing Machine in 100 Punchcards. I’ve uploaded a video to explain a small part of the read head (the Jacquard). One needle is shown out of a total of 28. The needle and anything else in the animation is not part of the Turing Machine, but is part of a machine that reads and executes the program, i.e. a computer I am working on, which is in part explained in this schematic. As the turingloom website is about a program for a Turing Machine and not about a physical Turing Machine, I hope to be excused from the requirement of infinite tape.”
