Not specifically arcade related, but...
I know many guys here and on RGP are always bemoaning having to work with surface mount parts. I guy I work with pulled this ball grid (.8mm pitch) DRAM part off, flipped it around, and rewired it (with magnet wire) to the board to correct a trace issue (time was of the essence!). The bus is running at 100MHz and the whole thing is working great!
Not recommended practice for sure, but I was impressed as hell that he could pull this off.. it took him 4 hours to do! He even made a twisted pair for the clock lines!
