Ok, before I get tarred and feathered let me say first, im not trying to install this in any dedicated machine. I have a tetris machine that is jamma. A friend of mine works on poker and slot machines (for Bally) that have the 20" touch screens in them. He told me last night that when the touch screen stops working they just throw them away. he says they have vga outputs just like a pc monitor. if i wanted to install one of these in my jamma arcade would i have to have a jamma pcb that has the vga port on it or can i use a vga cable and splice it in?
 
I don't know anything about LCD resolutions and whatever, it's to my understanding they're just low res.

if that's the case, then you COULD take a VGA cable and chop an end off and add pins that go to the R, G, B, H-V Sync and Ground pins ... then just splice in your existing JAMMA wiring to that.

determining which wire is which is the tricky part lol it's literally guess and check, take a wire and meter it against every pin and hope it's one of the ones you're looking for. we had to do this on a Pinball 2000, convert the VGA signal from the PC box to a regular CGA monitor.


that's if it's CGA to VGA resolution. different than the VGA port/cable. that's actually why we had to do the monitor swap on the Pinball 2000, the geniuses that had the machine before us must have assumed they needed VGA resolution because it connected with a VGA cable. I can also attest to such, on our Dance Maniax and DDR Extreme machines (the Konami 573) that you can output standard resolution signals via a VGA port.

First thing, the 20" touch screens in Casino games probably run at 800X600 or better (I'm thinking better). If you had an arcade board that could output VGA (60-n-1's) then you should be able to plug them right in. If you wanted to hack the cable all you would need to do is lookup "VGA pinout" then ohm the pins out wire per wire. I'd be really surprised if the gaming industry used LCD monitors that were capable of CGA (standard res). Ask your buddy if he knows what resolution that the poker games runs at.

Second, you shouldnt be worried about what any of these people on this board thinks about you putting LCD's in any game! ITS YOUR GAME....
