PREPARATION
Step 1: Disassemble the APB including removing the power connections tonthe track-piece and the connections to the ID sensors and slot sensors.
Once this has been done the mother board and the top board (LEDs and buttons) can be laid out as per the photo below.
Step 2: Cut the 16-way ribbon cable as shown below. This cable is very short and makes the repair too difficult if left in place.
Step 3: remove the remains of the ribbon cable from the main board and use a solder-sucker to open up the 16 holes. Later we will fit a 16 way header. The main board is now ready for the microcontroller removal and replacement. At this point it should appear as per the photo below.
