*UPDATE*
I have found with much research that the OPC 660 output connectors are actually standard DB15 male and female video connections, Thus you just need an adapter cable to run the connection. Since I have a DVI card ATI 9800, I can use the apple DVI to VGA adapter that comes with most mac G4's. luckily I have the long version. roughly 9" connector to connector. You can otherwise utilize a second monitor if you wish just using the video out port on the 660 card.
Hope this helps others
