wasnt aware there even was a uk pacman cocktail.the game was a midway one and they only manufactured the usa style ones.i think the most you will see pacman wise is a taito type si table top that has been converted to a pacman or some other generic table top running a bootleg on galaxian hardware,that way they could shave galaxian,moon alien,moon cresta and a few other games in there.
a uk pacman cocktail would only be the same as your usa ones but,running uk power suppy.
