Marton Kun-Szabo built a single/two board TTL computer, with a very low level single-instruction(?) approach, but with the help of macros and a C-like HLL he's off to the races:

A discrete-logic CPU that fits on a prototype board, and is able to run complex C programs, all without microcode.
I think it was a good choice to have native adder on the CPU and omitting basic logical functionalities, I haven't seen any homemade TTL PU on the internet yet that fits on a 4" x 4" board, and runs 64k C programs, and all this without microcode.
