The Trident TVGA8900D was based on the Trident 8900D graphics chipset. The Trident 8900D was a graphics chip developed by Trident Microsystems during the early 1990s. It was designed to provide VGA (Video Graphics Array) capabilities to computers, offering enhanced graphics performance compared to earlier graphics standards.

The Trident 8900D chipset supported VGA's 640x480 resolution and 256 colors (8-bit color depth). It integrated video memory and circuitry to handle graphics rendering tasks. While basic by today's standards, the Trident 8900D contributed to the transition from older graphics standards to VGA, which marked a significant advancement in computer graphics during its time.

The Trident 8900D chip played a foundational role in enabling PCs to display higher-resolution graphics and more vibrant colors, setting the stage for the graphical capabilities we enjoy in modern computing.
