The Canopus Pure3D II is a PCI-based 3D game accelerator launched in 1998. It is an add-on card that uses pass-through technology to work alongside an existing 2D graphics card, and it is built around the 3DFX Voodoo2 chipset. Unlike many Voodoo2 cards that followed a reference design, Canopus redesigned the board to their own specifications, shaving off length (only 7 inches) and eking out extra performance. The card packs 12 MB of memory: 4 MB of frame buffer and 8 MB of texture memory. It supports Direct3D, OpenGL, and Glide APIs, and can output to a television via composite and S-Video (NTSC/PAL). A small fan sits over the main processor for cooling, and a bright green LED on the board illuminates whenever 3DFX acceleration is active. Canopus over-engineered the cooling to allow overclocking up to 100 MHz. In the box, Canopus included every cable a user might need: a VGA pass-through, a ribbon cable for linking two cards in SLI, composite and S-Video TV cables, and even a Y audio cable to connect a sound card to the TV. A 20-page printed manual covers hardware setup with clear diagrams, and software installation is handled by a setup program that adds a property tab to Windows 95's Display settings, plus the Quick Control system-tray utility for on-the-fly gamma adjustment and an Application Launcher. The MSRP at launch was $329, with a slightly cheaper LX model available without TV output for $279.
