But like I said, I've only skimmed it so far.

The book is $35.00 though, but if its as comprehensive as it looks, it'd
be worth it.

one other thing is that its a TAB book which means it'll probably be on
the market LONG after the chips and any other special pieces are
obsolete and no longer on the market.
