The Quantum3D Quicksilver II is the hardware used in the Hydro Thunder arcade game.


Introduced in 1998-1999, the Quicksilver II is an arcade PC system based on a unique case design patented by Quantum3D, and an Intel Seattle BX2 motherboard with integrated sound. The case was designed for the environment of video arcades, featuring a shock-mounted hard drive assembly, twin fans with cross-flow ventilation at the rear, and all of the connections and drives are on the front for easy access by the operator. They can be configured with a number of different video sub-systems with either the Intel Celeron, Pentium II or Pentium III microprocessors. The system can be configured with network cards and console interface devices like Quantum3D's Arcade AMP, a force feedback interface controller and a JAMMA (Japanese Amusement Machinery Manufacturers Association) game console interface.

Hydro ThunderEdit

The Quicksilver IIs used in the Hydro Thunder arcade machines were configured with an Intel Celeron processor running at 333MHz, 64MB of RAM, a Quantum3D Obsidian2 90-2440 video card (featuring a 3dfx Interactive Voodoo 2 graphics processor chip and 10MB of RAM), a network card and one of two possible versions of the Microsoft Windows OS (either a custom variant of Windows 95 or an embedded version of Windows 2000).


  • The configuration of the Quicksilver II used in Hydro Thunder was also used in Off-Road Thunder.
  • Banshee has the same name as the 3dfx Banshee GPU used in the Quantum3D Raven, a video card that could be used in the Quicksilver II.
