Genesis 2 Arcade Mod: Need Help With PCB Schematics

Doh listed in the wrong forum, can we move to discussion?

So I want to do a non Jamma Genesis to Arcade mod. I figured the fastest/easiest way to do it would be to run the RGB monitor harness directly to the Genesis PCB.

Though I have found numerous AV output pinouts all of them say the numbering does not reflect the actual numbering.

Does anyone know where I can find a Genesis 2 schematic or does anyone know the PCB locations/numbering for the Red, Blue, Green, and Video Sync?

Also since this is a composite output I am guessing I will need to jump/splice the existing composite sync to the horizontal and vertical neg on the monitor?

Thanks

There are a few places with this info. A really easy mod...

Have you thought of just wiring the RGB straight out of the DIN to the Fingerboard.

You will not need a Sync splitter as it is already separated form the Composite Video.
But you will need to perform pad hacks as the MD has an encoder...

Good luck...

Wouldn't you also need an RGB amp to raise the voltage to arcade specs?

Personally, I think it's easier to just buy a viletim SCART to JAMMA adapter. That way you can basically use any console that has a SCART cable to put into your cab. No need to mess with sync splitters or video amp!
