Circus Charlie Arcade PCB Upgrade Compatibility for Original Konami Hardware
Confirm whether your original Konami Circus Charlie arcade PCB is compatible with the HighScoreSaves Free Play and High Score Save upgrade. The kit works with the original Konami hardware while adding modern score-saving and operator functions.
Choosing the Correct Circus Charlie Arcade PCB Upgrade
A Circus Charlie cabinet, marquee, or control panel does not by itself confirm compatibility. Vintage arcade machines may have been repaired, converted, or fitted with replacement hardware, so the actual game PCB should be identified before ordering.
The HighScoreSaves Circus Charlie upgrade is intended for documented compatible original Konami Circus Charlie arcade hardware. Confirm the original PCB, required Konami1 device location, 6809E processor requirements, and physical board condition before beginning installation.

How the Circus Charlie Konami1 Adapter Installation Works
The current Circus Charlie installation guide identifies the kit as containing a 6809 daughter card and Konami1 adapter. A 6809E processor is required for the completed installation.
The original Konami1 device is removed from the Circus Charlie PCB and stored safely. The Konami1 adapter is installed in its documented location, the 6809E is fitted to the kit, and the daughter card is installed on top of the adapter.
Before restoring cabinet power, verify Pin 1 orientation of the 6809E, inspect all processor pins and sockets, confirm that the adapter and daughter card are fully seated, and follow the current installation-guide photographs for final orientation.
