Obsidian2 200SB-8440
Advanced Voodoo2 based realtime 3D
graphics accelerators for professional applications
Obsidian2 200SB-8440 - Optimized for full screen realtime
visual simulation & training, PC-based Coin-op/LBE and interactive digital content
visualization applications.
Single board “SLI” design saves PCI slots
Designed with a unique 66 MHz PCI bridge chip architecture, the
Obsidian 200SB delivers better performance and improved reliability than dual board
“SLI” designs. Plus, its 66 MHz PCI interface provides twice the triangle and
texture download throughput of conventional Voodoo2 designs. The Obsidian2 200SB-8440V
features an optional MGV 2000 companion 2D/VGA windows accelerator daughter card that also
uses the PCI bridge to deliver the most powerful 2D/3D combination in the industry -- all
in a single PCI slot.
SwapLock capability for multi-channel applications
To eliminate frame synchronization artifacts between adjacent
monitors or projectors in multi-channel LBE and vis sim applications, the Obsidian 200SB
features a “SwapLock” capability that provides master/slave vsync, hsync, pixel
clock, and buffer swap sync for up to 16 independent graphics channels. In addition, the
200SB is the only Voodoo2 based board with driver support for multi-board/single-system
applications.
Simultaneous RGB and TV-Out
The Obsidian 200SB delivers simultaneous RGB XGA/SVGA/VGA and NTSC
or PAL TV-out outputs in either S-Video or composite formats - perfect for direct to video
or cost sensitive applications where large screen monitors are a requirement.
Authentication
The Obsidian 200SB features a unique, OEM-customizable
authentication capability that provides enhanced protection against unauthorized use -
perfect for coin-op/LBE games and other copyright sensitive applications.
