In many ways, as I watched Lisa Office System and MacWorks boot up (via trace logs), I saw many glimpses into the software design ideals and practices of the early 80's. I've never been an archaeologist, and don't really know that experience, I can guess at the rush and thrill of discovery. Seeing the machine code of various Lisa OS's fly by has been that experience for me. I could almost understand what the coders that wrote them were thinking, how they designed things, and why. I could easily tell what code was hand written assembly by an expert, or novice, what assembly was generated by compilers.
