After a few months of having the same game in my machine I decided to mame the sucker

. Turns out I have a Arcade VGA card laying around my house and nobody is using it so I decided to put it to use! Now I have a problem I pulled out my machine to look at the connector on the back of the monitor its like 2 squares together and I have no idea how plug it into the VGA card. Theres no slot for it so I think I need an adaptor for it but have no idea where to buy one from. Thanks for your help!
