The two Alpharetta machines listed above I went over and checked out. The Black Hole is a black hole when it comes to missing pieces. The top playfield is missing, all boards are gone and the small transformer has been raided. The Simpsons is missing the boards, backglass, displays and the art on the side of the head has been crudely repainted.
If you go there watch out for chicken droppings as you make your way to the garage.
