Tseng Labs
Founded in 1983 by Jack Hsiao Nan Tseng, Tseng Labs was a maker of graphics chips and controllers for IBM PC compatibles. Their first product was designed to allow IBM PCs to run the CP/M Operating System. Tseng Labs later introduced a combination multifunction and graphics, called Ultrapak, which upgraded IBM PC and XT compatible computers with features of an IBM AT. Ultrapak enhanced graphics by providing IBM MDA (Monochrome Display Adapter) and HGC (Hercules Graphics Card) compatibility with a special 132 column text mode.
Tseng's best-known products were the Tseng Labs ET3000, Tseng Labs ET4000 and Tseng Labs ET6000 VGA-compatible graphics chips, which were popular between 1990 and 1995 (the era of Windows 3.x)
Tseng Labs was purchased by ATI (now a part of AMD) in December 1997.
