Installed just fine & lots of options.
Moon Patrol seems to be the black sheep in the Williams lineup with a 3-board sandwich that the others don't have. This kit fits right next to the long sound board, maybe even a little too close on mine. I had to adjust the four mounting screws on the sound board to angle it a bit to make room but it's sturdy. The kit also extends past the bottom of the boards and can bump the coin box when the sandwich is positioned in its usual mount spot inside the cabinet. I fixed this by adjusting the position of the wood block on the near side of the boards (when looking in from the back) so the boards can't slide and bump the kit. Not a big deal and should be stable for life.

Easy to install, makes it fun to play my game again
As my title says this is totally easy to install and it does make it fun to play my game again looking at the high scores and not having to coin up all the time. These are super high quality as well.

Z80 8-Bit Microprocessor (40-Pin CPU) The Z80 is a classic 8-bit microprocessor widely used in arcade machines from the late 1970s through the 1980s. This processor served as the main CPU in many arcade PCBs, executing game code, processing player inputs, and coordinating communication with memory, sound hardware, and video circuitry. The Z80 became one of the most popular processors in arcade hardware due to its reliability and expanded instruction set compared to earlier CPUs. Because of its widespread use, the Z80 is commonly found in a variety of classic arcade games and remains an essential component when repairing or restoring vintage arcade boards. This processor uses a standard 40-pin DIP (Dual In-line Package) and installs directly into a compatible socket on the arcade PCB. Replacing a faulty CPU can often resolve boot failures, lockups, or other operational issues in aging arcade hardware. Key Features Z80 8-bit microprocessor Standard 40-pin DIP package Common CPU used in many classic arcade PCBs Handles core game logic, timing, and system control Ideal for arcade PCB troubleshooting, repair, and restoration Used In Arcade Games Such As Donkey Kong Galaga Donkey Kong Jr. Frogger Galaxian Dig Dug Xevious …and many other classic arcade titles Installation Notes Installs into a standard 40-pin DIP socket on compatible arcade PCBs Ensure correct notch orientation when installing the CPU Recommended for technicians performing arcade board repair or restoration *Manufacturer brands or markings may vary.
40-Pin Socket Specifications This 40-pin DIP socket is designed for reliable installation of integrated circuits and arcade daughter boards that use a standard 40-pin layout.
