Win Computer Technologies NT-200B

The NT-200B is representative of the first wave of affordable VGA upgrade cards based on Western Digital’s WD90C00 chipset. Introduced before VGA had become universal, it offered reliable IBM compatibility without the premium price of high-end graphics adapters. With 256 KB of video RAM, it was intended for mainstream business and home PCs rather than performance enthusiasts. Cards like this helped establish VGA as the default display standard across the rapidly expanding PC clone market.
