This 8-states Turing machine has 2 tapes. It is made using basic electronic components: logic gates, latches, shift registers, multiplexers, diodes, transistors... Its program is implemented by LEDs plugged into connectors.

I read Alan Turing's famous paper, but I have to admit I didn't understand it! Bamboozled by all the mathematical symbols and typesetting. One day I'll sit down with a fridge full of beer and grapple with it again. Maybe this gadget will help, I understand 1 and 0 and TTL.
