Way back when I built my home-brew progressive display http://newlifegames.net/nlg/index.php?topic=10148.0 , I used two pins to update the display. They were pins 3&4 on J12 of the backplane shown below. I can't seem to locate these pins on my schematic. I don't recall exactly what they are. Duh! I need to know because I plan to change my game theme and need to know if this is a general purpose 'coin in' signal or part of the progressive setup.  Scratch Head I'm thinking it was just a general porpose signal as I don't recall having to enable any progressive settings.  Any help would be appreciated, including where on the schematic J12 is.

Ok, I think I may have found the answer. It appears that J12 is indeed for the progressive. Since I am using a SP873 in my Haywire Deluxe, the progressive settings were done with the DIP switches vice with a SET chip. I really need to start documenting this stuff better when I do it. Duh!
