Title: jamma 6 button jpac question
Post by: deadenddonkey on March 03, 2006, 08:15:42 am
alright, so i finally have everything up and running perfectly.   My PC2arcade machine works great after many hours of adjustments and replacing a ipac with a jpac and that same jpac with another jpac(there was something wrong with a chip although Andy was great help as is usual).  So, now a new question.  How exactly would i get all 6 buttons to function on my machine with my jpac?  Currently through the JAMMA connector there are only the standard 3 on each player working.  I understand i would have to wire to the screw terminals on the jpac, however here is my problem. when i bought my arcade machine it was already set-up for 6 player support for the marvel vs capcom 2 game already in it. I of course want to keep support for this game and any other JAMMA games i might buy. Exactly what would i Need to keep the jamma wire configuration while still being able to play full 6 button support with my mame games?

many thanks for any help
David

I'm guessing that your MvC2 machine has a small extra harness for the 6 extra buttons? These are sometimes called a 'Kick Harness', since they were used to add the kick buttons in SF2. If it does, you could buy a JAMMA fingerboard, cut it to size so it fits your kick harness, then wire your fingerboard to the extra JPac connections.

They're on his Connectors page:

A type 1 connector should do the trick.

I think it just means that you'll need to solder your wires onto the pads (the silvery connector strips on the board) with no option to criss-cross the wires (like his Type 2 fingerboard). Direct is fine for what you're doing, once your wires are soldered on you won't ever have to change them.

I had a kick harness in my cab (using a jpac) and I just cut it off and stripped the wires back a little and put them in the screw terminals of the JPAC.  (They are labeled pretty good... P1B4, P1B5, etc)

I cut the wires a few inches away from the harness, just in case I decided to put a jamma board back in the cab, I could always solder the wires back to the harness.

Whole deal only took me a few minutes.  Just hav a VOM ready to tone out the buttons to the harness wires.
