Quoted from luvthatapex2:All Tommys had the shaker board installed at the factory, but no shaker. Only the prototype software supported the shaker. If I recall the bombs dropping triggered the shaker. I'd be interested how yours is hooked up as someone did this after the fact. I've always wanted to add the shaker to my Tommy!
I recall that Tommy had it added for Japan only. Something about how the laws worked meant keeping the same number of motors in every game made things easier for DE.
OP, can you check what software version you have?
