It ignores analog electronics (transistors as amplifiers, not just switches). It uses relays for clarity, but real computers use CMOS transistors. Petzold mentions this but doesn’t dive into semiconductor physics. You can find legitimate, new copies of this

Understanding Charles Petzold’s "Code: The Hidden Language of Computer Hardware and Software" (2nd Edition) Code is a primer for architecture, not a programming manual

Use free online logic simulators (like Logisim or CircuitVerse) to physically build the adding machines and flip-flops Petzold describes. Code is a primer for architecture

The assembly language for the Petzold-1 is toy-like. Readers wanting to write real assembly should move to a RISC-V or ARM textbook. Code is a primer for architecture, not a programming manual.

The journey continues into the physical world. The book demonstrates how flashlights, switches, and even a seesaw can be used to construct logic circuits. It explains:
