V6366 (as used in old Hercules Graphics cards )
The Hercules Graphics Card (HGC) is a computer graphics controller made by Hercules Computer Technology, Inc. that combines IBM's text-only MDA display standard with a bitmapped graphics mode. This allows the HGC to offer both high-quality text and graphics from a single card. The HGC was very popular, and became a widely supported de facto display standard on IBM PC compatibles connected to a monochrome monitor. The HGC standard was used long after more technically capable systems had entered the market, especially on dual-monitor setups.
