For the last few days I’ve been building Ben Eater’s awesome 8-bit breadboard CPU, mostly to scratch an itch I’ve long had to do this. In the future I will be building a much more ambitious 16-bit pipelined CPU.
I’ve built just enough of the circuit that it can actually execute instructions. Well, it can fetch them, so it’s executing two microinstructions per instruction (fetch into instruction register and increment the program counter). RAM is full of random data.
