WTB: Credit Multiplier board for Pacman / MsPacman

[ManiN]

Looking at the schematic I'd guess 4 & 7 as they are signal in and out. The rest seem to be power, ground, etc. for the board itself.

pin 2 to pin 4 - pin 7 is reset from the pcb, whereas pin two clocks the flip flop. conn 2 to 4, drop a coin and if it coins up whoo hoo!
what i coouldnt tell form the schematic is whether pin 2 connects to one coin sw, the other, or the credit switch. check connectivity btwxt coin sw input and the coin 1/coin 2/credit switch to see whcih one it is conected to, with a dmm if you have issues

Also a snapshot of the schematic:

Should 1 and 2 be jumped too so they both throw the signal to 4?

looks like it should, otherwise if you have a 2 coin slot door the other wont work!
