I am thinking of making a 4 bit vertical CPU named CRCT, Choco’s Really Cool Thing (Don’t Question). It will have I/O registers, RAM, an accumulator, and 3 sets of PROM. I am currently modifying the instruction set.
4 Bit CPUs are the coolest. Go for it.
So I finished CRCT v1 a while ago and forgot about this, and yes, there are no registers. Deal with it. I am start v2 which will have same thing, but 4 sets of PROM, 7 registers, 32 bytes of RAM. Yes, i did say byte. and also technically 8 cache registers

And here we have the CU and the PROM
