Cosmic Avenger Arcade PCB Upgrade Compatibility for Original Universal Hardware
Confirm whether your original Universal Cosmic Avenger arcade PCB is compatible with the HighScoreSaves Free Play and High Score Save upgrade. The kit installs at the Z80 processor location while keeping the original Universal game board in service.
Choosing the Correct Cosmic Avenger Arcade PCB Upgrade
A Cosmic Avenger 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 arcade PCB should be identified before ordering.
The HighScoreSaves Cosmic Avenger upgrade is intended for documented compatible original Universal Cosmic Avenger arcade hardware. Confirm the game board, Z80 processor location, CPU socket, and available daughter-card clearance before beginning installation.

How the Cosmic Avenger Z80 Daughter-Card Installation Works
Installation begins by locating and carefully removing the original Z80 processor from the Cosmic Avenger PCB.
A riser socket is inserted at the CPU location to provide clearance above nearby capacitors. The HighScoreSaves daughter card is then installed into that CPU socket, and the compatible Z80 processor is installed on the kit.
Before restoring cabinet power, verify Pin 1 orientation, CPU alignment, daughter-card seating, socket condition, and clearance underneath the new daughter card. The current guide notes that nearby test points may sometimes need to be moved away from the underside of the kit.

Cosmic Avenger PCB Compatibility FAQ
Which Cosmic Avenger arcade PCBs are compatible?
The upgrade is intended for documented compatible original Universal Cosmic Avenger arcade PCBs. Compare the actual game board and CPU area with the current installation guide before ordering.
Which processor does the Cosmic Avenger kit require?
A Z80 processor is required. The current installation guide shows the original compatible Z80 being removed from the game PCB and installed on the HighScoreSaves daughter card.
Why does the installation use a riser socket?
The riser socket provides additional height so the daughter card can clear capacitors near the original Z80 location on the Cosmic Avenger PCB.
What should be checked underneath the daughter card?
Verify that no original PCB components or test points contact the underside of the daughter card. The current guide specifically calls for checking this clearance before the cabinet is powered.
Does the upgrade replace the original Universal Cosmic Avenger PCB?
No. The documented compatible original Universal PCB remains the underlying arcade platform. The HighScoreSaves daughter card upgrades that original hardware rather than replacing it with an emulator or generic multicade system.
