There were few articles in european
"elektor" about a computer build
completely out of 74xxx. Was beginning of the 70's, and was called (?)
the 74-computer.
Somewhere I have a Radio Shack book, a simple introduction to computing.
All I can remember about it is that it's landscape format, has a green
cover, and is spiral-bound along the top edge.
Anyway, it contains a schematic for a very simple processor built from
TTL (IIRC). Simple, in that it has 16 locations of 8 bits for the program
memory, each 8 bit word is a 4 bit opcode and a 4 bit data memory address
IIRC.
I ought to find said book and spend an enjoyable afternoon soldering it up...
