Now ive done this before with my old converted Jamma cab, but when i build my new cab there will be no Jamma Harness, and thus will not have a J-PAC. So how do i wire a coin mech and credit baord so that it works with mame, am i able to run the wires from the coin mech and credit board to a I-PAC, GPWIZ-49 or Keywiz??
