The interconnect board (Banzai Run and later)

From Banzai Run on, a long narrow interconnect board, under the CPU board or on a backbox side wall, is the junction for GI, controlled lamps, flashers, switch matrix and coil power. It holds the GI fuses and the flash lamp resistors (only R2; the 330 ohm R1 was dropped), plus MOC3010 opto-couplers for flipper lane change. Earlier games did lane change with a second switch on the flipper button. The Banzai Run version differs from all later ones.
