It is an excellent resource for hobbyists building their own 8-bit computers or working with breadboard logic. Technical Specifications and Versions
The cryptic "I---" in your query likely refers to the visual or symbolic logic notation Foster uses throughout the text. Foster was a master of abstraction without obfuscation. He famously begins not with the history of computing, but with the NAND gate . His argument is radical in its simplicity: from a single universal gate, one can build a flip-flop, a register, an adder, and eventually a central processing unit. i--- Computer Architecture Caxton Foster Pdf
