  Ooh, awesome! Thank you! It would be cool to weave some rope memory with this. https://en.m.wikipedia.org/wiki/Core_rope_memory https://en.m.wikipedia.org/wiki/Core_rope_memory

    Yeah, rope memory is genius. Practical storage from such as simple structure. There's a demo somewhere on Youtube of someone who made a 7-segment decoder with rope. Pretty simple circuit compared to what you need to read-write core memory.
