Trident?  \n\nare they still making video cards?  I haven't seen one in....10-12 years I'd guess.\n\nRegardless, you would need to consult HP/Compaq for wiring diagram, though I doubt they still have it.....but you don't know 'till you ask.\n\nI seriously doubt that you will make this work unless you know how to solder....and well.
