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...
