Applications

The Trident TGUI9680 series was a widely used budget/value VGA graphics chipset in the mid-1990s, appearing on PCI cards and integrated into many OEM motherboards of the era. Cards like this were the standard display solution for business PCs and entry-level consumer systems running MS-DOS, Windows 3.1, Windows 95, and Windows 98. The TGUI9680-1 supported standard VGA and SVGA resolutions and was well supported by DOS game drivers and early Windows display drivers. Today these cards are primarily sought by retrocomputing enthusiasts building or restoring period-correct 486 and early Pentium systems, where a period-accurate PCI VGA card is preferred over a modern GPU. The PCI form factor makes it compatible with a wide range of mid-1990s ATX and AT desktop systems.
