| Some general quesitons about first MAME cabinet setup |

| Umgar:
Howdy all, I've been lurking on this board for a while reading up about cabinet construction while I slowly acquired the parts to put my own MAME cabinet together. I finally have everything ready to do the final assembly and had some general questions - mostly about the monitor. Just want to make sure I'm not missing any critical steps in my build process before I push the "on" switch :) So here's what I've got: - MKII Arcade cabinet with a working monitor model WG 25k7197 (tested by powering on the original board / MKII boots up and looks great) - J-PAC interface - 3 Ghz / 2GB RAM PC with an ArcadeVGA graphics card (the new PCI-E one w/ 512mb video RAM) - X-Arcade controls For the actual setting up of of MAME and the PC I'm well experienced so no issues there. This will be the first time I actually hook a PC up to an arcade monitor though. My question is this: with a J-PAC and ArcadVGA card is it really just a matter of plug it in and turn it on or is there more I need to do to get the best picture possible? I know the J-PAC will not allow an out-of-range signal so there shouldn't be an issue with blowing the monitor out, but I notice that there is still a lot of stuff hooked up to the JAMMA interface which is probably not necessary anymore. For instance, there is a blue box at the bottom of the cabinet which seems to have a lot of stuff wired into it - no idea what this is. It seems to be separate form the power supply itself, I can post a pic if that helps. Should I basically aim to disconnect and remove absolutely everything except for AC power that feeds the display... or with a J-PAC & ArcadeVGA does it not matter? Thanks! ;D Umgar |

Here's a picture of the mystery component. What is this thing? ??? Should I remove it or does it matter? |

Another thing that caught my eye... there is a single bare wire hanging out of the cable that goes to the monitor (see picture). As I said previously, the monitor displays a normal picture when tested with the original MKII board, just curious as to why this wire would be hanging free and if this is something I should change before I hook it up to the PC. |

When you do so, trace the AC wiring back (looks like it is the purple pair) to the source and disconnect it rather than leaving the wires hanging loose. |

Does it connect to the monitor chassis (the circuit board) or the metal frame ? |
