Nibble Disassembly Lines : Volume 1

Nibble Disassembly Lines: Volume 1 is a compendium of all of the Apple II DOS 3.3 "Disassembly Lines" articles that appeared in Mike Harvey's Nibble magazine as well as Call-A.P.P.L.E. magazine during the 1980s. Written by Sandy Mossberg, a medical doctor, avid reader, science fiction fan, bird watcher, photographer and especially a self-taught programmer who had one of the longest-running columns in Nibble. If you are an Assembly Language programmer who wants a greater understanding of some tricks of programming the Apple II computer, then this is the book for you. Disassembly Lines brings these extensive and knowledgeable articles together into a two volume set. Features: - 30 articles covering the internals of DOS 3.3, the System Monitor, RAM, the Apple II Floppy Disk system, and related topics. - ROM and RAM usage for a myriad of purposes including hiding programs. - Introduces aspects of Apple II system commands and internal system calls that are not normally used without an extensive explanation of their workings. - Source code (compatible with Merlin assembler) and ready-to-execute assembled binaries are included on the accompanying floppy disk images.
