Quantum3D AArdvark
Quantum3D does indeed make some Arcade equipment, this videocard is based on a 3DFX Voodoo Banshee, whats the difference bewteen this and a normal Voodoo Banshee?? Notice the two ports on the picture, one port is a VGA connector (for VGA monitors) the other is a 9pin EGA connector (for 15kzh/24khz arcade monitors).
You flash the BIOS to what arcade monitor you want to interface, either 15khz (CGA) or 24khz (EGA), the VGA output is never changed.
To achive the output to lower resolution monitors the AArdvark does anti-aliasing, a simple two-by-two anti-aliasing scheme to compress the 2D into a low-resolution display format.
15khz the output is 320x240, and supports either 320x240 or 640x480.
24khz the output is 512x384, and supports either 512x384, 800x600, 1024x768.
The VGA screen must be one of the above modes and running at 60hz for the video output to be correct.
As the card is almost identical to the Banshee/Voodoo3 in DOS, all references to extra Aardvark functions our noted.
