+# 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
