That's the discontinued board for our Laurel 3 or 5 column machines, this one about 20 years old looking at the microprocessor code. The replacement is part #899-77 and it has a larger dot matrix LED display and allows for
credit card systems to function with it. The sell for about $300 and it is plug and play. You can keep your current
door or replace it with one that has a larger LED window so you can see all of the new display.
