You've got quite the mutt there. It looks like a Super Pac-Man converted to Ms Pac-Man converted to a Multi-game.
Super Pac-man cabinet
Ms. Pac-man Marquee
Galaxian Bezel
Ms. Pac-Man control panel with wrong joystick and a hole punched in it (probably for a multigame)
Honestly this would be costly to convert back. Wiring harness, game PCB, Marquee, Bezel, Fully populated Control Panel, side art, etc. It would be less expensive to find a working Super Pac-Man.
As much as I'm into preservation and de-conversion I'd pass on this one. If It's already a multi-game, I'd roll it with black paint and keep it or sell it as-is.
