MultiPass Technology

The inclusion of Multipass Technology within the RocketCPU ensures seamless compatibility
with either WPC 89 or WPC-S pinball machines.

RocketCPU eliminates the need for the Security Chip (U22 or G10) and can be effortlessly installed on any WPC-S pinball machine, automatically generating the required security key, ensuring compatibility without constraints.

Integrated No More Reset

Tired of untimely resets? No More Reset prevents any +5V issue that can affect your WPC pinball machine.

No need to buy the addon: it’s already integrated onto the RocketCPU!

High Accuracy Clock

Ultra-precise clock and RTC oscillators integrated into the RocketCPU board ensure an exceptionally stable clock with virtually no drift.

Smart Status

Smart Status simplifies the monitoring process by providing clear, visual cues that indicate your pinball machine’s status. 

Whether everything is running smoothly, Multipass mode is engaged, the battery is running low, there are system errors, or voltage levels are outside the optimal range, with Smart Status you’ll know immediately if any action is required.

RocketCPU with Smart Status ensures you can enjoy your pinball machine to the fullest without interruptions or uncertainties. It’s the ultimate tool for both beginners and experienced enthusiasts, offering peace of mind.
