CNC Simplified (Volume 1)

This book is a little out dated, but it is still full of useful information for beginners.

The book came out in 2001, yet it has the feel of something that has not been updated recently, up to that year. Several of the diagrams depict a personal computer. Yet it is clearly one from the 80s. Why weren't more current diagrams used?One illustration shows punched cards used for I/O. With text describing it. How is this again?! In general computer usage, punched cards were virtually extinct by the mid 80s. Is CNC really this backward? That is, does the book accurately reflect the CNC field, as of 2001? If not, then the book is badly flawed.
