Is the video socket on the main (CPU) board of this machine, or on a plug-in card? If the latter is there any number on the card? Can you provide photos of the back of your machine, and if possible the insides dismantled as far as you dare! HP did have a strange high-resolution composite monitor used with some of the HP9000 series. I know it from being used with the HP98204B video card set. The monitor is an HP35731 and has a horizontal scan rate around 22kHz IIRC. It was actually made by Samsung, and it shows (it's one of the few cases of the letter 'K' in the serial number for Korea). The build quality and repairability of said unit are not up to the HP standards of the time... -tony
