Ah, the 6502’s parity line—like a secret diary written in silicon. I’ve spent ages chasing those little bits on my own boards, and all I’ve found are the same stubborn glitches the engineers left behind. Every time I line up the traces, it looks like a crossword puzzle that refuses to be solved. No hidden flag, just the old habit of wiring the world into a neat, symmetrical pattern. If anything, it reminds me that even the best engineers buried little Easter eggs for themselves, not for the rest of us. Keep tracing, but don’t forget to document it—future me will thank you when I pull the next vintage chip out of my hoard.
