I haven't seen this before. Looks factory. The video wires are soldered to various resistors on the chassis. I'm going to remove the board and the video wires but was curious if someone knew what the purpose of this was.

Thanks

If you decide to sell or trade that WG NTSC board, a few people here are KLOV are looking it.

Thanks. What's a fair price?
Based upon my experience alone, $75-$125. The more of the required wiring you can include, the better, including the power wire from the chassis.

That's a 5-pot K4900 chassis, so you may just as well to sell it all together, since the WG NTSC PCB is already installed. :)

I think I had to assemble one for Dragon's Lair when I worked with gamefixer. was a K7000 NTSC board on a K4900. so I had to manually run all the wires for it based on some intelligence somewhere. I typically take pictures of everything I work on but I didn't get any of that then.
 
FYI: If the wiring on it is factory, then you have a 4921 monitor. These were originally in Dragon's Lair cabinets as well as G07s with the Electrohome NTSC board. Yes, your WG NTSC board is sought after and $75 to $125 is a fair price if it is working. Other than the factory connections for the NTSC card, the 4921 is a standard 4900 chassis.
 
I was going to cap it and repair the chassis but R363 has been broken off and that hunk of the board is nowhere to be found to be stitched back together.
