There were dookickies that took care of the mode

mine were a bridge between duh Mac and a VGA-BNC

mode (by shorting 2 pins) should be readily available
on duh net I would think. Macs (older ones anyway) had
to select a video mode at boot, or no video signal
would output.
I'm surprised to hear that *PMs* don't output
SOG.
Depends what you mean by PM. I thought the earlier
models did, but what do I know.
Starting with the 9600, apparently, so the older series PM's
apparently still generate SOG:

CSYNC (Pin 3 on the Mac video connector) is still available, however.
I went for a "quick and dirty" and just tied that to Green with a 470
ohm resistor. It'll do for now. Nice crisp display.
I forgot how darned heavy those old HP monitors were. I hope the
plastic case top will support it. :)
