On the arcade monitor there is a large square connector mounted in a square hole in the metal chassis below the power transformer. I think it is a 12 pin connector (P1). Pins 1 and 2 are the video input. Pin 1 is the video signal and pin 2 is the video ground (shield). Go to Radio Shack and buy any one of these 3 cables: 42-2370 (3 ft long), 42-2371 (6 ft long), or 42-2372 (12 ft long). Connect the shield of this cable to pin 2 of the monitor connector and the center conductor of the cable to pin 1 of the monitor connector. Now you can plug this cable into your video output of a VCR, etc and see the video on this monitor.
