thanks dad, but i have just got it to work, and then i had the NO PC key, which it seems you cant set until you have a cash door button. so i typed 5 in there ( dont know what number it should be , figure that out later) and now i have absolutely nothing displayed on the 7 segment leds, guessing it the sec meter or reels as they havent moved. i will see if i can fix, if not i will pm you, thankyou.
