I hope someone out there can help me with these questions - I haven't seen them
discussed before in any articles I've stumbled upon.

 Is it possible to use a TTL monochrome monitor designed for standard Hercules
 graphics with a SuperVGA card in SOME or ANY of the graphics modes?  (The card
 has both analog and TTL outputs and uses the Trident chip.)

	1. Is it atleast possible to use the this combination in Hercules graphics
           mode? How about CGA, EGA, (or lower resolution modes of VGA?)
	   I'm especially interested in the EGA possibilities.
	2. How much danger is there to the monitor?  What can I do to minimize
           this risk?
	3. Is it possible to have both VGA card and Hercules cards installed
           simultaneously?
	4. Does anyone out there have a chart of the required monitor frequency
           for each of the popular graphics 'standards' (HERC, CGA, and the
           many EGA, VGA modes)
