Since everyone is skipping my Focus thread in which I added this question:

My 4600 does not have the shift jumpers, and I need to shift the image slightly left and slightly up. Can I add the jumper pins? Where does the other end of the jumper wire attach for both horizontal and vertical?
 
Not ignoring it, been busy today preparing for a road trip to pickup a pin for the Wife unit. Let me go look and see what I have got.
 
Well, looking at the schemtatic, the horizontal shift jumper is tied to one side of the horizontal width coil. I attached some alligator clips and tried touching each spot where the horizontal shift pins would be, and the picture did nothing. Apparently there isn't any circuitry between where the pins are and whereve they tie into the rest of the monitor.

This is a K4605, btw. Apparently some had more than others.

I've tried two different JAMMA boards, and both have about an inch or so of black on the right side, and about a 1/2" of black on the top....
 
I haven't even been able to find their spots on the board. Been staring at the layout in the manual and can't see it there either....
 
You have an older model with with a P307 interface card? If so, then the circuitry is not there. I believe that you can create a VR202 off of the header. Looking at the scat the P317 & P318 interface card had a 10K pot on it. (VR202)

Looks like all you would need is a 680 ohm cap and a 10K pot.
 
I have some other interface cards with both pots. Perhaps I'll toss one in to see what happens...
