A graphics display system for PCs developed by Van Suwannukul, founder of Hercules Computer Technology. Suwannukul developed the system so that he could produce his doctoral thesis on PC equipment using his native Thai alphabet.
First offered in 1982, the original Hercules system filled a void left by IBM's MDA ( monochrome display adapter ) system. MDA produces high-resolution monochrome text but cannot generate graphics. Hercules systems generate both high-resolution text and graphics for monochrome monitors. The resolution is 720 by 348.
Hercules has been supplanted by other standards, such as VGA, and is now obsolete.
