A-17651 WPC-S MPU

A faithful, electrically and visually accurate reproduction of the original WPC-S MPU board, built using modern, high quality components and matched routing.

Technical Features
• Supplied with 32K×8 SRAM or 32K×8 NVRAM (Note: Williams ASIC, MPU, Security Chip and game ROM not included)
• High risk devices (U14, U16–U20) are socketed for straightforward diagnostics and replacement
• Quality Molex KK-series connectors for power and switch inputs
• Built using original spec components from reputable manufacturers
• Authentic schematic correct design — all component placement, connections and routing match the WPC-S original board and schematic
• Fully tested

Why choose this board?
WPC-S MPU boards are now decades old, and many have suffered:
• Battery leakage damage and failed components
• Corroded connectors
• Repeated field repairs
Even when repaired, you’re still relying on components that have already lived a long service life.

This board is a clean, drop in replacement that behaves exactly like the original — same timing, same routing philosophy, same component choices — but built with fresh silicon and clean copper.

For restorations, long term reliability, or machines that see regular play, a new board is often a better solution than continuing to patch an ageing original.

• Drops straight in
• Looks and behaves like the factory original
• Uses quality components and connectors
• Matches the original schematic and routing
