# Dancing Stage Fusion dedicated cabinet JAMMA edge wiring

The Dancing Stage Fusion dedicated cabinet has different wiring than
classic Dancing Stage/Dance Dance Revoluion Machines that are either based
on 573 analog/digital hardware or Python 2 hardware.

The cabinet connects to the main PCB using two JAMMA edge 28-pin connectors.

The following sub-sections provide full pinouts taken from a stock
Dancing Stage Fusion dedicated cabinet. `NC` denotes to "not connected".

## Pinout primary 28-pin connector

This 28-pin connector is actually following the JAMMA specification.

## Pinout secondary 28-pin connector

This 28-pin connector is the same as the primary connector but does not
follow the JAMMA pinout specification.

The follow hardware is connected on this connector:

* +5V power source
* Serial cable to EXT I/O
* Lights I/O cable to AMP box
