Adapting a 520-5080-00 flipper board to non-EOS games

Steps

• The original 520-5033-00 is no longer made, so a 520-5080-00 can be converted for Robocop to Rocky & Bullwinkle (and the test Playboy/MNF games). Pin 2 of CN1 is the key pin, for orientation.
• Component side: clip pin 10 of CN1 off flush so it cannot reach the harness.
• Solder side: bridge capacitor C10 (next to CN1 pin 10) with a wire so it is shorted out.
• Solder side: add a jumper from CN1 pin 1 to pin 2.
• Solder side: add a jumper from CN1 pin 6 to pin 7.
• Solder side: cut the trace that joins CN1 pin 2 to pin 7.
• Mark the board as converted for games without EOS switches (Sega service bulletin 103).
