I don't know if anyone's mentioned it yet, but
there was a Radio Shack
book called something like 'Understanding Computers'. It was A3 in size,
landscape format with a sprial binding on the top edge IIRC. Green cover.
There was a design in there for a simple 'processor' with 16 locations of
RAM. I suspect it could easily be built from TTL.
The only one I remember was BCD style 4 bit cpu. It would be nice to do
nice calculator as retro-techology but I have no idea where to get NICE
push button switches and key caps.
