Assembly Lines: The Complete Book is now available! The book contains all 33 of Roger Wagner’s articles from Softalk magazine, as well as appendices on the 6502 instruction set, zero-page memory usage, and a beginner’s guide to using the Merlin Assembler. The book is currently available for 40% off on, and will be available at Amazon in a few weeks. Note: Roger Wagner has released the book under a Creative Commons NonCommercial-ShareAlike license, and I’m currently working on the eBook version.

FYI, I uploaded disk images of the Assembly Lines programs to the Asimov website:

There are DOS and ProDOS versions. Disk1 contains the programs from chapters 1-17, while Disk2 contains the remaining chapters. Note that a few of the programs (in the DOS chapter) will only work in DOS, not ProDOS.

You can download a copy of the Merlin assembler for DOS at: v2.48 (DOS 3.3).dsk

And for ProDOS: v2.58 (ProDOS) Disk 1-2.dsk
