The real value of Code is in its explanation of technologies that have been obscured for years behind fancy user interfaces and programming environments, which, in the name of rapid application development, insulate the programmer from the machine. In a section on machine language, Petzold dissects the instruction sets of the genre-defining Intel 8080 and Motorola 6800 processors. He walks the reader through the process of performing various operations with each chip, explaining which opcodes poke which values into which registers along the way. Petzold knows that the hidden language of computers exhibits real beauty. In Code, he helps readers appreciate it. --David Wall
Topics covered: Mechanical and electrical representations of words and numbers, number systems, logic gates, performing mathematical operations with logic gates, microprocessors, machine code, memory and programming languages. --This text refers to an out of print or unavailable edition of this title.

I'm not a book person, I rarely (almost never) sit down and read a novel.
But this book... I wish this was a 20-book series, like some sort of vampire series.... Read more
This is the college textbook that was never recommended.
It gives easy to understand examples to explain difficult to grasp concepts (especially for beginners)... Read more
