The Taito 8 position rotary controller was also used in "Wild Western" as well as "Tin Star" . When hooking one of these up a switch needs to be wired in to cut the ground when not in use because the controller always has at least one microswitch engaged at all times. MAME see's this control as an 8-way joystick. I have one of these on my first MAME cab as Frontline is one of my favorites. It was the pioneer for games like Commando and the Ikari series ect..
