Why Choose This Adapter

This ingenious solution leverages the fact that Tempest's spinner uses the same encoder technology as half a trackball. The adapter repurposes existing fire and zap button wires (unused by Quantum) to carry the second axis data, eliminating complex rewiring. You can either use the convenient jumpers for a quick conversion or remove them to run dedicated wires for maximum flexibility.

Ideal for arcade collectors who want to run both Tempest and Quantum games without maintaining separate cabinets or completely rewiring their setup.
