HI Today a friend brought me COIN UP. I want to connect it to one of my machines. And pass through MAME. According to what I read on the site of http://www.ultimarc.com/controldiags.html Zener Diode need to connect to pass through the IPAC. And that for the IPAC will not be damaged. i have no Zener Diode ,Perhaps because it was connected to the original arcade machine :-\ My question what Zener Diode type should I buy? What voltage of Zener Diode? |

Remember that the band on the zener diode goes toward the coin signal line (reverse biased), NOT toward ground. Scott |
