| Dual MAME & Jamma cab setup??? |

Hello... I think this is my first post here, lol... but I'm not sure. :o Anyway... I'm gearing up to add MAME to a current Jamma cab and I'm wondering if there's a way that I can use my PC with MAME and still be able to swap jamma PCBs in and out of the cab. I'd like to use the same control panel for both PC and jamma but of course I don't want to fry my jamma PCBs. My current plan is to purchase a few of the products at ultimarc.com including an ArcadeVGA... buy using the U360 or J-pac/i-pac can I still use standard jamma? ((I'm not sure abou the U360... but can I wire up the buttons/J-Pac & Jamma in together in series?... and then just make sure the PC is off when using jamma?)) Thanks for any suggestions or help in this. |

I am interested in seeing what others have to say about this as well... I may be interested in doing the opposite. I am not sure I want to do that but I am curious to see what the BYOAC community has info-wise on this. Good luck! |

If you use the jpac from ultimarc, you should be able to just swap the jamma plug between the two. I have seen dual jamma connectors on ebay which let you switch between two jamma boards; they may work with the jpac, but I don't know. My cab was a Tekken II, and I had to have the kick harness unplugged when the jamma harness was plugged into the jpac. I don't really remember too much about it. I swapped back to the Tekken II board once soon after I converted the cab, but I never have since. Paul |

Thanks for the reply.... I was reading up on the J-Pac and it seems like it should work... The swap won't fully work though... but I've got an idea. The PCBs I have are all "jamma+"... like Killer Instinct with 6 buttons and Mortal Kombat with 5 buttons. My thought is to wire the extra buttons into the J-Pac just as the directions say... but then continue the connection of the extra buttons to another harness for the PCBs. ((I'll try to draw it with text)) |>-------> Jamma PCB | ^ Standard Controls --------> Jamma harness< | |>---------> J-PAC ----> MAME PC | Buttons 5 & 6 ---------------------------------------------^ I think this will work... when I have the Jamma board hooked up the J-Pac will act like a pass-through of the wire. Then, when I hook the J-Pac back up to the jamma harness... I just unplug the "extra" 5 & 6 button harness, then with the J-Pac powered it should still see my extra buttons let the PC use them, and since the "extra button harness" is disconnected, there shouldn't be any problems. I do have a possible issue though... when I was reading about the J-Pac, they say I should disconnect my power supply... but if I do this, I'll need to keep that to power my jamma boards. If I keep the power supply installed and have the J-Pac hooked up to the PC along with the jamma harness... will I kill the J-Pac or PC... or maybe both??? |

Paul --- End quote --- It seems like you did I was trying to explain... just without using the J-Pac as a passthrough for the non-standard buttons. ... Do you have any problems with the power supply and the J-Pac/PC??... or did you remove the power supply from the jamma connector and just use it for the monitor? Also... when you did the swap... did you leave the J-Pac attached to the PC?... or did you disconnect it from the PC too? |
