Full PEP8 compliance. Also, booleans have been inserted where they make sense (introduced in 2.3!) and I haven't knowingly added anything that will break 2.3 compatibility. At this point the code really doesn't look like it was written ten years ago. Hooray!

; Test file for base 6502 opcode compliance


; This odd little source file uses every addressing mode


; of every opcode, and uses the opcode itself as the argument


; to each instruction that takes one. The resulting binary's


; bytes are thus in strictly increasing numerical order.
