 IIRC, these are fairly common as they were used on many SGI and Sun
 workstations.  Its called a 13W3 cable.

   Sun 13W3 cables do not work correctly with SGIs and most monitors.  I
disremember what the signal is, but pin 10 needs to be *removed* from
the Sun cable.  IIRC, SGI is SOG and Sun is composite sync.
