   Does anyone know what frequencies the 98785A supports?  I don't remember.
   Something in the back of my head tells me it's a Catseye monitor.

   (Looking at it more as a potential PC monitor.)

		 No to unlimited wiretaps.  No to enforced `decency'.

Here is an XF86Config file for this monitor.

Basically, you can only get a little better than 1024x1168 out of it,
(I'm getting 1050x787) and, of course, you can't see anything while
the machine is booting.

If, like me, your monitor only has RGB inputs on the back, you have to
make a little circuit to get the syncs on the green input.

The circuit looks like:

	G -- (neg) 100uF Capacitor (pos) ----
					     |
					     |
	HS ---- n n ------------------ 1k resistor
		 p
		 |
	VS -1k trim

This works by turning off the green signal when the syncs are being
sent, and costs about 3 dollars to make with parts from (ugh) Radio
Shack.
