A little project I made because 1. I wanted something better than Overture, 2. I didn't like the unused instructions in Overture, and 3. I wanted to make something. Basically, this is an 8-bit CPU capable of slightly more than Overture (such as accessing 256 bytes of RAM), but really the achievement for me was managing to make all 256 states of a byte an unique, valid instruction.
(the ALU is based on the overture one hence spoiler)

Oh yeah excuse the spaghetti, I'm inexperienced and a bit lazy so it was inevitable when I had to start thinking about more than 'place a bunch of bit switches'
In terms of I/O you have the level input thing and the 6 higher bits in the flag register, and the output is just the level output. If i needa add anything it's going on one of those three places
