PJ5 TTL CPU

I just got a tip about the PJ5 TTL CPU project and had a loook at their build log. This is a really cool project with a ton of thought. I highly recommend having a look. It appears to me that they are running their machine faster than they originaly anticipated and they're not using microcode with a goal of one clock cycle per instruction rather than bouncing an instruction to ROM and back again taking up precious cycles to complete. Really cool project.
