TECH: Yoke Flipping a 25" B & W monitor???

Hello,

I was hoping that someone on here can help me out. Does anyone know how to screen flip a 25" B & W that was used in a game with a mirror? I picked up (2) 25" Black & White monitors. The problem is they both came out of games that used a mirror. (LeMans and Sea Wolf) and there seems to be only 3 widing wires to the yoke. 1- Black, 1- Green, 1- Red and the place for the Yellow is empty. Pic is attached. I'm trying to put one of these into an Atari Firetruck which did not use the screen flip and when I plug both of these into my Firetruck the screen is reversed. Tried to Ohm read them, but gave me voltages consistant with both Horizontal and Vertical. Any help would be greatly appreciated.

Thanks in advance,
Shawn
 
but he only has 3 yoke wires?

so its kinda strange...

look @ the yoke, is there a jumper between the h & v yokes connections?
 
It sounds like you may have a XM701. If it is then yes they only have three wires and you need to flip the image at T3.

I explain it in this thread post #2.

the picture shows a non-flipped monitor.

PS Nice game I'd love to get a fire truck
