I finished the logic for the computer after countless weekends and decided to finally submit this project.
The computer is now running in LOGISIM (a logic simulator).
I already prototyped the logic gates and tested them up to a 5 MHz clock. I got inverters as well as NOR / OR gates to work at accurate speeds, so those are the gates I´ll stick with for the complete build. The logic diagram consists solely of those three gates. I´ll explain the building blocks in separate videos.
