Re: Help with an RGB Conversion...

There are (of course) the 3 R, G and B outputs on the computer. In
addition, there is 1 Sync output, only 1. We have a 5 (one too many)
BNC to VGA cable, but I believe this is typically used to send signal
from VGA to RGB (right?). Along with the R, G & B on this cable, there
is a Vertial and Horizontal. We've tried connecting this cable to a
newer VGA monitor in a number of ways. There are 2 cases where we see
anything at all. First, when we connect any one of the colors to the
Sync we do see staticy Horizontal lines of that color. Also, when we
connect the Vertial Cable to the single sync output, the monitor
indicates a "frequency out of range" error. We are, on the other hand,
able to get a clear and steady signal on and older monochrome monitor
using a Single BNC to Single BNC cable, if we connect this cable to the
Green BNC output on the computer. We also get signal on the red and
blue, however the image isn't stable.

Two things, 1) It could be a composite sync output, 2) since it's video the
system probably outputs stuff at 50 Hz which is too low for a modern VGA
monitor.

Can someone tell me definitively if buying one of these monitors will
work? And if not, what a good cost effective solution would be?

You could try finding more information on the computer in the console (it
could conceivably be an Amiga 1000 for example). Also you could try
measuring the vertical & horizontal sync frequencies (eg using a 'scope) so
you have an idea what specs the monitor you're buying will have to handle.
