Diamond Multimedia
Diamond was a graphics and sound card manufacturer for the IBM PC and its compatibles. Their first series was the "SpeedSTAR", based on the Tseng Labs ET4000 and ET4000AX chipsets. This was followed with the "Stealth" from 1995, which offered 3D acceleration under Windows - these used a chipset from S3. The SpeedSTAR range became their low-end / budget range at this time. Later on the Stealth cards incorporated both 2D and 3D capabilities. Moving towards the late 90s, Diamond introduced the "Viper" range, relegating the Stealth range to be mid-range.They merged with S3 in 1999.
