ok, from left to right it goes R,G,B, ground, +vert sync, +horiz sync, ground, -vert sync, -horiz sync. To attach to an arcadevga you have to match the pinout from the card to those pins--red line to red , green to green etc (and no this does not mean colour of wire on the monitor cable--you'd be surprised how many people ask me that) I believe ultimarc sells a ready made break out cable just for this purpose.
