Amazon Reviews:

"When I was first charged with the lightning bolt of the promise of software possibilities, I found this book. It helped me see how to view a microprocessor's capability in a comfortable, natural progression of understanding. It provided me what I wanted to know where I expected to find it. The references to related information, missing in most documentation, always seemed to be both appropriate and conveniently located. It was as if Zaks knew my own, unique desire to learn and how it naturally unfolded. It felt as though he had prepared each of the steps that I would need by having been where I was. It served me tirelessly as a reference until it fell apart. Books of this type are hard to find today."

"When I was first starting to program I came across this book. It was not only a well written, complete reference on the Z-80, it was a perfect reference book. Now, when I program, I generally need several reference books hanging around. Mr. Zaks said it all, cleanly, concisely. Any success I had in my later programming, I have always felt that his book was at the core."
