If those game chips, or Eproms came with the glass and the reel strips, then I'm guessing you have what you need. Those need to be swapped out with the other game chips off your games MPU Board. The numbers in the chip match to the sockets on the board. They will fit both way in the sockets but if installed backwards can result in damaging them. If you notice the chip has a dot or notch on the top of one end. That end goes into the end of the socket with the notch in the end of it. Be careful not to bend or damage any legs with removing or installing your new chips..
