This review is from: 128 Machine Language for Beginners (Paperback)

The first thing I noticed about this book was the similatites with his ealier book "6502 Machine Language For Beginners." A lot of content, ilistrations, and pictures were taken strate out of the other book. Because the 8502 is opertationaly Identical to the 6502 line this is not a problem.
The next thing of note was this book was much better. It includes several new Apendex that include a much better breakdown of the the opertaions than his 6502 book. The 6502 had only a chart detaling operation, op code, aftected registers, and addressing modes. Now every operation has several paragraphs describing what they do.
There is also a secion that includes usfull subrutines, and other tips that you will use constantly. Several 10 byte subrutines you'll never want to live without.
The downside to this book however is the complete glossing over of advanced math. A much more thurough discritption of multiplications is covered, however division is left to simble bit shifting multiples of 2.
Over all this is an exelent introduction to machinlanguage, not jsut for the Commodore 128 but the 6502 instruction set as well. As the title indicates this is a beginers book, so it isn't a complete picture. It will however get you started.
