I would appreciate recommendation for purchase of a high quality high resolution VGA card which supports (640 x 480, 800 x 600, 1024 x 768) 256 color display resolution. I would prefer using a card supporting whatever standards seem to be evolving for high resolution VGA -- and if possible capable of supporting operating in linear address (rather than paged) address space under SCO UNIX SYSV/386 3.2v2. Because my project involves image processing it is crucial that the recommended card support eight bits each of R, G and B so I can display the full range 256 level enhanced greyscale and 256 color mapped images. In addition, I would be interested in knowing which VGA cards will be supported by SCO UNIX SYSV/386 ODT, QEMM/386 X Window Server, Roell's X Window Server in high resolution 256 color modes. Thanks, AJ Annala

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... -- ------------------------------------------------------------------------------- Robin P.
