I bought a new used Nintendo jamma adapter. Went to plug in my donkey kong 2 board stack into jamna cab and get what's in pics. I checked the voltages at the power supply and thaey are all good. Getting +5.1v, -5.3v, and 12v at power supply. The bad part is I don't know if this is a fully fuctional board though.

The weird thing is I have a fully functional working Popeye 2 board. Gets same results. Then I plug back into my Popeye cocktail and board works fine. Don't know what is going on. If somebody could help me out that would be greatly appreciated.

Thanks in advanceImageUploadedByTapatalk1358302526.989973.jpgImageUploadedByTapatalk1358302542.382543.jpg
 
I am going to ask a dumb question, but where is the adjustment for the sync on a wg 7000 monitor. Or is it on the board.

Thanks
 
Thanks 88mph, you was right it was the sync. I just wasn't turning the knobs enough.

Thanks
