This Creature from the Black Lagoon pinball by Bally came from Europe. Many games from Europe come in very dirty condition. We think this may be from the wax they use, perhaps a spray on wax for furnature. Spray wax will turn to a black soot powder that gets into everything. Some local operators do the same spray wax thing to save time. This game had a problem not starting up, the CPU would not start. We changed the voltage regulator and cleeaned up the power and data connection to the CPU. The service notes follow:
