The P3-ROC is the next evolution of the Multimorphic line of pinball controllers. Designed for use in their P3 modular system, it is well suited to custom game construction thanks to that very same modularity.
Hardware
The P3-ROC hardware consists of five main boards:
- P3-ROC is the main controller device which plugs into a PC via USB and allows the PC to communicate with the various input/output boards.
- PD-16 allows control of up to 16 solenoids or other high voltage devices.
- SW-16 supports up to 16 switch inputs.
- PD-LED allows control of up to 84 single LEDs or up to 2048 serial LEDs.
- Power Entry provides a simple and safe way to connect power between multiple power supplies and game devices.
Additionally, they provide a number of support devices such as long range optos, RGB LED boards and audio amps.

P3-ROC Controller Board
Although it appears complicated due to the number of connectors on the board, the majority of the .100" headers are to support the P3 long-range optos and are not relevant to most custom game makers.
The theory of operation, dip switches and what the LED mean is explained in the documentation but the key connections are:
- J1: Power input (5V) using a standard PC power supply connector
- J2: Power input (5V) using standard pinball .156" Molex connector
- J11: Serial connector 0 using .100" Molex for SW-16 boards
- J12: Serial connector 0 using .100" Molex for PD-16 boards
- J13: USB connector to computer
- 'J14: Serial connector 1 using .100" Molex for SW-16 boards
- J15: Serial connector 1 using .100" Molex for PD-16 boards
Serial Interface
The P3-ROC uses the RS-485 serial protocol to communicate to the attached boards. Designed for high EM environments, it has excellent error correction and robust signalling and is well suited for the noisy world under a pinball playfield.
Note that the Switch and Driver serial connectors have different pinouts, to help avoid mixing up connectors when assembling wiring.
