Sort of off topic, but this is a GREAT book about reverse-engineering software: http://www.amazon.com/Reversing-Secrets-Engineering-Eldad-Eilam/dp/0764574817
Of course it's about PC software, not 25-year-old 68k Mac programs, but the general concepts are the same for reasoning backwards from a disassembly to reconstruct a program's high level behavior.
