Quick update number 3 on this, the machine's diagnostic leds are fully lit and it won't run diagnostics or boot. If I remove the co-pro board, the machine does then go through it's diagnostics process and I get a beep. However there's no HT to the monitor. I did get heaters, but there's no fizz or static to the screen so something's down in the monitor circuit on what I guess passes for HP's analog board.
