COIL BOUND BINDING. Note: This is the second printing: It contains all of the corrections as of May 2017 as well as an updated back cover. Roger WagnerÕs Assembly Lines articles originally appeared in Softalk magazine from October 1980 to June 1983. The first fifteen articles were reprinted in 1982 in Assembly Lines: The Book. Now, for the first time, all thirty-three articles are available in one complete volume. This edition also contains all of the appendices from the original book as well as new appendices on the 65C02, zero-page memory usage, and a beginnerÕs guide to using the Merlin Assembler. The book is designed for students of all ages: the nostalgic programmer enjoying the retro revolution, the newcomer interested in learning low-level assembly coding, or the embedded systems developer using the latest 65C02 chips from Western Design Center. ÒRoger Wagner didnÕt just read the first book on programming the Apple computerÑhe wrote it.Ó - Steve Wozniak
