This is mad crazy nerdy. I remember having to code a 12 bit CPU in verilog for a digital design class in college. It was absurdly complex, but very fun to do. But that was also instantly loaded into a solid state FPGA. Magic.
But building a CPU out of wires using 1970's vintage parts? Wow. That's something else. By hand! Good lord.
Steve Chamberlin, the creator of this project, calls it the BMOW -- The Big Mess of Wires. *grin*
