Mike, According to this page http://www.shrubbery.net/~heas/sun-feh-2_1/Devices/Monitor/MONITOR_LCD_18_C… the monitor will do 1280x1024x60 which is the standard output of video cards on DEC 3000 models - although I would need to know the particular card you are using to be sure. I've found a few monitors to be compatible with the DEC 3000 so I think you are likely to be in luck, although sync-on-green is definitely a requirement. Depending on your video card you may need an adapter cable - the 3W3 connector breaks out to RGB which can then be fed into a VGA connector using a cable such as http://www.ebay.co.uk/itm/SVGA-VGA-to-4-BNC-Cable-HD15-Male-to-4-x-BNC-Male… although clearly the less interconnects the better. I was quite surprised to find that 3W3 connectors are still readily available and cheap so you could make your own cable up. Regards, Mark.
