The Quicksilver II was an arcade system that was produced by Quantum3D. It was the hardware platform that was used in the original Hydro Thunder arcade game, which came out for the arcades in March 1999.


Introduced sometime in 1998-1999, the Quicksilver II is an arcade PC system that is based on a unique case design that was patented by Quantum3D, and an Intel Seattle BX2 motherboard with integrated sound.

The system's 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 of the unit, and all of the connections and drives are on the front for ease of access by the operator.

The Quicksilver II can be configured with a number of different video sub-systems with either the Intel Celeron, Pentium II, or Pentium III CPU.

It can be configured with network cards and console interface devices, such as 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 that are used in the Hydro Thunder arcade machines were configured with an Intel Celeron CPU that is running at 333MHz, 64MB of RAM, a Quantum3D Obsidian2 90-2440 video card with 3Dfx Interactive Voodoo 2 GPUs and 10MB of RAM, a network card, and one of two possible versions of the Microsoft Windows operating system (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.
  • The Medium-level boat 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.
