https://scratch.mit.edu/discuss/topic/318309/?page=2 The machine currently runs a binary counter program The project builds a doubly linked list out of JavaScript arrays, this way the memory of the Turing machine is only limited by the computer emulating it. (when using an array or string as memory the ECMAScript specification puts a limit to its length (not really significant as there is no computer with more than 2^53 bytes memory (the limit is 2^53 items))) Currently there is a limit of around 800 items in the memory, because the block that displays it crashes if there are more items, but you can remove that block and then it really becomes limitless
