SGIs did sync on green. Sun uses a dedicated signal. SGI trinitron-based
(Sony OEM) monitors should handle both. If you boot your SS10 to the point
where you think it is dead and then unplug/replug the keyboard it should
bring you back to the ?ok? prompt. Shows the system is still running OK
without output.

  Jonathan may be on to something here. I only deal with
Sun stuff and am
 mostly unfamiliar with SGI stuff. However, I use LCD displays with
 13W3-to-VGA adapters on my Suns and, relevant to this discussion, I know
 that the adapters used with Suns are different from the ones with SGIs,
 though I don't know the details.

  Bill,
 Are you sure the SGI monitor will work with the Sun graphics adapter? 
 Just
  because the plug fits doesn't mean the
monitors are compatible, when it
 comes to 13W3. It may be just transferring control to the video console 
 and
  *appear* to be locking up, and you're not
getting anything out of the
 display as a result.
 Do you get diagnostic LED patterns on the keyboard LEDs?
 Thanks,
 Jonathan
