Completely agree, this was just the first foray into documenting this project and I wanted to make it less heavy on the details of the hardware to reach a wider audience. I'm definitely going to put up a more technical post and the sources/schematics as soon as I can.

To answer your questions, it's hard wired with the control logic made out of the simpler chips (7400, 7408, 7432 etc) but the rest of the system does contain more complex chips, the 74181 ALUs being the largest.
