A must-have for Crazy Climber owners
I installed this kit in my original Crazy Climber PCB, and it worked perfectly. The instructions were clear, installation was easier than I expected, and the board booted right up. Free play is a great convenience, but the high score save feature really brings the game to life since our scores are finally preserved between power cycles.
The kit is high quality, installs without modifying the original PCB, and has been completely reliable. Shipping was fast, everything was well packaged, and customer support was excellent when I had a question before ordering. If you're restoring or maintaining an original Crazy Climber cabinet, this is an upgrade that's absolutely worth it. Highly recommended!

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.
