Video Modes Supported : Hercules
The Hercules monochrome display adapter was identical to IBM's monochrome adapter
except all 720x350 pixels were directly addressable. This gave Hercules users a
monochrome 720x350 graphics mode. Games marked with this attribute support this
mode directly, eliminating the need for a "CGA simulator" program.
Hercules is part of the Video Modes Supported category.
