Temporary conversion until I have some money to get another crt... anyways I get a no signal message from this. The board boots up and displays the logo so it's working ok. I am using the 8 pin connector with this. Not sure if joust is an issue cause of positive sync. I have tried changing the clamp values and resolution settings as well as using that auto down button to try and sync it up. I did get a picture for a split second when I changed the resolution on the board and it went away back to no signal. I have also tried swapping the sync wires around as well.

Does anyone have any knowledge of these and have any suggestions on what I can do to get this to display a picture?
 
I added the composite wire on pin 7 of the video connector from the pcb and switched to the 5 pin connector on the GBS to simplify things but still wont sync. I ran into a similar issue with an A.P.B. conversion I did but when I added the composite wire it synced right away. Very strange.
 
Doesn't the sync need to be inverted on Williams games
to work with a GBS-8200 ?
