Description:

The GC201 multimode graphics controller from G-2 Inc (Milpitas, CA) incorporates most of the circuitry required to implement a graphics subsystem that emulates IBM's Enhanced Graphics Adapter (EGA) for the PC, as well as IBM's Color Graphics Adapter (CGA) and Monochrome Display Adapter (MDA), and Hercules Computer Technology's Monochrome Graphics Card. To create a complete EGA subsystem with the chip, you need only add video RAM, a BIOS EPROM, and a 74LS244. The ic costs $31 (10,000). The company offers a $149 evaluation kit consisting of an EGA card (for the IBM PC) that has a GC201 on board. - Steven H Leibson, EDN November 12, 1987
