This is the CPU of a 4-bit computer I’m working on. So far it holds a total of 12 bits of data, but I’m pretty sure from how I designed it I can add more registers. The ALU can only do addition and subtraction since those are the only ones I know so far, it’s quite user friendly, it has signs that tell you what an indicator means or what a lever or button does, the internals were a nightmare to build but I think I got it as small as I could.
