Using CGA to VGA converter on Monaco GP Screen Issues...
Hey guys!
I'm using the CGA to VGA jammaboards.com video converter to put a replacement VGA monitor in my Monaco GP mini cabinet.
The Monaco GP did not have the standard 5-pin molex to connect to the conversion board, so I wired in the P11 slot molex connector. The problem with this is that it has 2 separate wires for H Vid Sync and V Vid Sync, but there's only 1 sync wire coming from the Monaco board...
I spliced them all together, and my picture is bad. I'm wondering if I need to invest in the standard RGB GRN SYNC 5-pin JAMMA connector to splice into, or if wiring the H and V sync together with the single Sync wire from the board is okay (meaning the scrambled video is an issue with the PCB board).
I've attached some pics to show what it's doing. For the most part, the sync is constantly moving in and out of being able to see the screen. A picture captures a single moment, but were it a video of the gameplay, you'd see it cut in and out of scrambled, rolling mess.
Any thoughts?
