Controlling Williams, Bally System 11 Machines

You can connect your machine using the SNUX System 11 board to any WPC controller such as the Multimorphic P-ROC (not the P3-ROC). This solution requires the existing driver boards.

Another option is to use the Arduino Pinball Controller (APC) which also replaces the original driver board. Nothing except the APC board is needed to control the machine using MPF. This can be optionally used together with LISY to emulate the original ROM.

More technical information can be found in the PinWiki Williams System 9 and 11 page.
