Upgrade Your Gravitar Arcade Experience
Restore and enhance your original Gravitar arcade machine with a professionally designed Free Play and High Score Save Kit built specifically for authentic Atari vector arcade hardware.
Original boards often lose high scores, rely on aging components, or suffer from unstable resets. This upgrade modernizes your PCB while preserving the original gameplay, controls, timing, vector graphics, and gravity-based gameplay that made Gravitar one of Atari's most challenging arcade classics.
Unlike multigame systems or reproduction boards, this kit keeps your original arcade PCB intact while improving long-term reliability for collectors, operators, and restoration projects.
