Well maybe I am dumb, but I know lots of stuff isn’t compatible with Gottlieb. I have a Teed Off from 93 with a dead dmd. I also have a working dmd from my Champion Pub from where I put in a color dmd. Conventional wisdom tells me any dmd will work like they do on other brands, but I remember reading somewhere that that isn’t the case with Gottliebs. Dear pinball gurus, set me straight? Thanks.
