I just picked up a centipede cocktail table. It plays blind. The wire harness is pretty hacked up and i have spent hours and days trying to connect a monitor. I have a 13" cga monitor that im not sure if it works, so i want to connect an lcd to test it out. I have a cga to vga converter. The problem is the harness is so bad i cant make sense of it. Does anyone know the pinout for this. Which is r,g,b,ground,h sync, v sync, or does it use a composite sync? Anyone able to help me make sense of this? Photos attached.


 
If you google "centipede Pin out" you'll find the pinout there's a few different sites that have them some are missing some signals so you want to look at all the ones to fill in the blanks for example there's a composite sync but I don't think one of the sites show it the other doed
 
Hit up Ken, Wldfire here of Golden Age Arcade parts. He has a Centipede unhacked cocktail harness that I gave him so he could replicate.
 
I typically refer to Mike's site ->

And for the wire colors, I use ... wait for it ... yes ... can you guess ... THE SCHEMATICS!! :)

I re pinned the harness using the schematic. I am using the RGBS connector on the cga to vga converter. I have the comp sync connected and still no picture. I have tried combos of h sync and v sync along with the composite sync. Do i need video return connected also? Ive tried the RGBHV connector also with no luck
