P-ROC (Pinball Remote Operations Controller) is a programmable pinball control board created by Jerry Stellenberg that allows hobbyists and professionals to replace CPUs in Williams/Stern pinball machines with USB-programmable alternatives. It emerged as a key enabler of the homebrew and custom pinball community, inspiring both amateur builders and professional developers to create new games and modify existing ones. The platform has influenced notable figures including Eric Priepke (Cactus Canyon reprogramming), Josh Kugler (custom machine building at American Pinball), and Wolfgang (Rocky Horror Pinball), demonstrating its significance as both a technical foundation and career catalyst in modern pinball development.
