many forms of multimedia technology . they have produced graphics cards motherboards modems sound cards and mp3 players however the company began with the production of the trackstar a pc add on card which emulated apple ii computers . they were one of the major players in the 2d and early 3d graphics card competition throughout the 1990s and early 2000s . the company was founded by chong moon lee and h. h. huh who acted as the technical designer . diamond multimedia later merged with s3 incorporated in 1999 after a long time cooperative business arrangement when s3 decided to expand their business from producing graphics chipsets to manufacturing retail graphics cards . the move paralleled the 1999 3dfx purchase of stb systems which changed 3dfx from a graphics chipset supplier to companies including diamond into a vertically integrated graphics vendor and direct competitor to s3 . however the first major product after the merger branded as the s3 savage 2000 was a commercial failure . growth in the add on sound card market also an ongoing diamond business was tempered by the 2000 bankruptcy of aureal semiconductor and subsequent asset purchase by vertically integrated creative technologies . with these market failures the new combined diamond s3 company decided to change direction and leave the pc addon board market . sonicblue was formed . diamond multimedia resurfaced in 2003 after the brand and assets had been purchased by best data . diamond again built expansion boards . the company was the defendant in a significant copyright case for its rio digital

first launched in the early 1990s and were usually based on gui accelerators from s3 graphics . the line later included chipsets with combined 2d and 3d capabilities . initially the stealth line was diamond s high end brand but transitioned to midrange after the viper line was introduced . notable members of the stealth family have been the diamond stealth 3d 2000 by far the most popular s3 virge based board . the diamond stealth32 using the tseng labs et4000 w32p chipset was capable of impressive price performance especially in dos . the diamond stealth64 graphics 2001 with the ark 2000pv mt chipset was known for excellent dos performance at the time . the diamond stealth ii s220 using the rendition verite v2100 2d 3d accelerator was popular with enthusiasts for its excellent price performance for both 2d and 3d gaming . a special bios patch was released by diamond for the stealth ii s220 which brought its clock speed up to the same level as the high end verite v2200 chip resulting in equal performance at a significantly lower price . in the middle of the stealth line up diamond chose to implement a numbering scheme to differentiate their cards . for example the diamond stealth video vram was rechristened the diamond stealth video 3xxx . the numbers had more than a random meaning . specifically they tell the buyer the card s memory amount and type . the stealth video 3240 uses vram 3 is equipped with 2mb initially 2 and is upgradeable to 4mb 4 . if the first digit was 2 then the card used standard dram . the numbering scheme confused many people since diamond just renamed current cards with new names . the stealth video 3240 was simply the old stealth video vram . new cards did also use the scheme however such as the s3 trio64v cards .

2120 the diamond edge 3d was the first consumer 3d accelerator card based on the nvidia nv1 chipset . the boards were designed to be an all encompassing entertainment solution as the chipset and board included full 2d 3d acceleration an audio engine capable of general midi synthesis and the ability to use sega saturn gamepad controllers . the architecture of the nv1 predates the microsoft direct3d philosophy and as such game compatibility was a problem with the diamond edge boards . limited and slow direct3d supporting drivers did eventually show up but performance was inadequate and buggy . the audio engine further received poor reviews regarding midi quality which was a common standard for multimedia music playback at the time . listing of edge 3d branded boards diamond edge 3d 2xx0 sgs

voodoo graphics and voodoo2 chips which did not contain a 2d engine requiring a separate vga card connected externally using a pass through cable . when the 3d engine was called into use the 3dfx based card would disconnect the 2d pass through signal and begin driving the display directly . both voodoo and voodoo2 based offerings were in production until the stb 3dfx merger . the series was highly successful as the voodoo graphics and voodoo2 chipsets introduced consumer grade 3d graphics into the pc and arcade markets whereas such capabilities had previously been present primarily in very high end cad and graphic design workstations . a critically acclaimed feature of the monster 3d ii and all other voodoo2 boards was the capability to connect two identical boards in a sli scan line interleave configuration . in sli a pair of voodoo2 boards splits the effort of rendering the 3d scene between alternating raster lines allowing performance to be nearly doubled . listing of

merger the viper line was diamond s high end offering . initially it consisted of a graphics accelerator board for vlb or pci that was a combination of two graphics chips . for non gui environments such as dos the original viper used an oak technology oti 087 display chip with its own 256 kb dram . this chip was rather slow and basic . the viper se card moved to a weitek 5186 chip with 1 mb dram for non gui functions . for gui environments such as windows the viper cards used a weitek graphics co processor which accelerated many drawing functions and performed very well for its time . the original viper used the weitek p9000 p9001 while the viper se used a weitek p9100 both lines equipped with 2 4 mb vram . the separate slow dos chip was a problem for owners who played dos games because these chips were quite slow and had limited and buggy vesa bios extensions implementations . while the gui accelerator was very capable drivers from diamond were rather buggy and were only revised a few times during the lifetime of the card . 2 towards the end of the 1990s the viper line consisted of nvidia based graphics cards . the diamond viper v330 used the highly integrated riva 128 accelerator that featured very capable 2d 3d and video acceleration . the later diamond viper v550 and v770 utilized the riva tnt and riva tnt2 accelerators which were evolutions of the riva 128 . in 1999 diamond was acquired by s3 graphics and became primarily a supplier of products based upon their graphics accelerator chips . the diamond viper ii z200 was based upon the s3 savage 2000 a supposed nvidia geforce 256 killer . unfortunately the chip itself was not fully functional and the drivers were very buggy . partial listing of viper branded boards diamond viper weitek p9000 vlb pci
