Standard VGA DAC's are limited to six bits per color(RGB), giving only 
64 shades of grey.  Other than that, the Orchid Prodesigner II supports
the resolutions you desire, and it's a real good card.  I'm not sure about
SCO compatibility though, but it's build on the Tensng Chip Set so it
should be fairly compatible...
