The above comparisons show that the Neo Geo stick is a custom Seimitsu model made for SNK in the late 80’s. The LS-30 (Ikari Warriors, Guerrilla War, etc.) and LS-32 belong to the same era. The Neo Geo joystick uses Matsushita microswitches for the stick and Tokai switches for the buttons, just like Seimitsu sticks and buttons. Japanese SNK cabs use Seimitsu parts exclusively which goes to show there was a close relationship between SNK and Seimitsu so it’s understandable that when SNK needed to manufacture an arcade stick for their home system they turned to Seimitsu.
