Got my hands on a paperback copy awhile back, and just finished it off this week during 5,000 air miles. Boy, I could have made good use of this book back when I was 15. Probably the best intro to machine language for the various 8-bit Commodore computers ever written. Examples include mixing BASIC with ML, extending BASIC with new commands, and writing interrupt code.
