This was very pre-VGA.  However, the monitor could take either 
analogue RGB or TTL RGBI levels.  The fact that it worked with VGA 
when it came out was pretty much happy coincidence.  This was not 
unusual on multisync monitors of that era.

There was (maybe "is") an outfit that offered ISA and PCI cards with 
modified firmware to handle the sync issues.    You just took a 15-
pin to 5-BNC cable, set a jumper on the board and you were in 
business.  I just gave away a 20" Sony with a Mirage card recently.  
I think it used a Tsenglabs ET6000 chipset.  Earlier Mirage cards 
used one of the S3 chipsets.

The cards would also work with RGB+HV separate sync monitors as well 
as SOG.  I've still got a 17" HP/Sony monitor stashed away.
