Hi, hope this helps. Make sure the machine is powered off and remove the CPU board from the card cage. Remove the U3 eprom from the board and replace with the clear chip. Make sure it is the right denomination clearchip and the notch of the eprom is facing to the right. Reseat the CPU in the card cage and turn the power on. The machine should bong one time and a series of numbers should populate the credit, win and coins played display. Turn machine back off and remove the CPU board again and replace the clear chip with the U3 eprom and make sure the notch is facing the right. Reseat the CPU in the card cage and power the machine on. The machine should load and “clr†should display on the credit display. Press the red diagnostic button on the card cage until it removes the clr from the display and the reels initiate the test spin and the machine should be ready to play. Hope this helps.
