This document describes how to make an adaptor to play a Gauntlet or Gauntlet II PCB in a standard 2-player JAMMA cabinet. This procedure requires no board modifications. This document was inspired by Chad Gray's Converting Defender to Gauntlet document, which I hope to use to JAMMAtize my Robotron board set Any Day Now.

1. Getting your parts and tools together

Describes all the parts and tools you'll need for converting Gauntlet to JAMMA
2. Wiring up Power and Video

Covers creating the connectors for power and video. This should be enough to get the game up and running, so you can verify that your PCB works.
3. Wiring up Controls and Coin Switches

Covers creating the connectors for the player controls, and for adding credits to the game. At this point, the game is fully playable.
4. Sound

Gauntlet has unamplified stereo sound. Most JAMMA cabinets require amplified mono sound. This page describes some of the options available, and the option I chose for my cabinet.
