Taito cocktails get no love at all.. Pretty ugly and the small monitor doesn't help it at all.. But, if it works and there isn't any acid damage on the CPU pcb.. The board set is easily worth $200 or more, as people are using them for zookeeper.. The game is really only worth what you wanna pay
Good luck! If the game doesn't work and there isn't acid damage, usually the ps is dead.. Easy fix!
