I remember CAD being a major driver for PCs with high-end graphics cards; specifically AutoCAD was rising quickly in popularity around 1990 as PCs were able to compete with very costly CAD workstations.
My memory about the high-end graphics cards of the time is sparse. I do remember the TI TARGA compatible cards, which were popular for photo-realistic graphics, and I think could work with AutoCAD as well. And I remember Number Nine cards being highly regarded by some AutoCAD users.
I am mainly interested in the period from 1988 to 1992-3. At that time, SVGA was new (VGA even somewhat new), and lower-cost video cards lacked the resolution and performance desired by AutoCAD users. I think they were aiming for 1024x1024 pixel resolution with accelerated 2D.
So, what were the most capable/popular high-end video cards for CAD on PC's at this time, and what were their capabilities (resolution, color depth, monitor freq., VRAM capacity, etc.)?
