I'm sure it was one of these that I had hooked up to a PC at one point - I also had a 16" workstation monitor which was sync-on-green and for which I built an external module to combine the sync outputs from the PC. There used to be quite a few websites out there explaining how to do all this - I believe there may even be a Linux HOWTO document on the subject somewhere (I don't think I have any documentation on the subject these days though). I assume if you're using a PC running some form of windows you can rework the graphics drivers somehow to drive the monitor properly?? It was easy under Linux, and these sorts of monitors were best for building X terminals based around old PC hardware running Linux (not something I've done for a while though...) cheers Jules
