I was looking up some info in one of my IC databooks and randomly opened on an interesting part.  The 74H87 implements the front-end processing for the ALU.  You might find the 74H87.pdf datasheet interesting.

Maybe if I get bored I'll do a 7400 series design for the ALU.  Back of the envelope estimate is 30 ICs, about 20 square inches of PCB allowing for I/O and power supply connectors.
