Back in my Apple II+ days, I spent a great deal of time programming 6502 assembler. I learned a great deal of the language by studying the disassembly of the Apple ROM (written primarily by Woz) that was conveniently included in the user manual and studying programs written by others and published in a variety of Apple-centric magazines (Nibble come to mind). I wrote straight assembler programs as well as a hybrid assembler/Applesoft Basic. I'd written assembly programs for the IBM 360 in college so I undertood the gist but the 6502 just seem friendlier. Very fondly revered times.
