The g07 has the standard video connector.
The 6 pin connections are (from right to left) E1 thru E6
E1---Red
E2---Green
E3---Blue
E4---Ground (connect RGB grounds here)
E5---Pos. V sync
E6---Pos. H sync
J1---Ground
J2---Neg. V sync
J3---Neg. H sync
So for the arcade vga you need e1-e4 rgb-gnd
then j2 and j3.
I had to use separate syncs for the g07 with a arcade vga,
you also might want to look at the sync mod (Some g07 shipped with the wrong components installed on the board.)
Sync Fix
On the monitor board, replace C303 with a 10 uF@50V capacitor with the
positive lead towards the collector of X305. Then replace C501 with
the capacitor taken from the space C303.
Hope I haven't confused you more.
