Negative Positive
Title: This book looked promising but it ultimately disappointed
Review: The most frustrating thing about this book is that it does not explain anything about how the circuits work. This makes it almost impossible to fix the errors in the circuits as shown (yes, there are errors). Also, some of his choices for components are dubious, like the 25-pin serial port connectors (why not use a 9 pin?) and the flat (ribbon) Centronics printer cable with 36-pin connector.I also agree with most of the complaints in the other reviews.This book could have been so much better if only the workings of the circuits were described (e.g., why a certain resistor value was chosen, why one circuit needs external power and one doesn't, etc.)
Is the review positive or negative?
