Based on AD65 Serial Number shown below




First we need to cut a few tracks starting with JP10 & JP12 located in area 1 above.





Now head to area 2 can cut JP20







Time to flip over the board to Area 3

be careful not to damage the door close switch when working on the bottom





Next job on the rear is to cut the track that controls the 50hz/60hz modes

Cut the track in-between the the vias, marked in yellow. You will be soldering on to the bottom via near where it is marked TP103 (in blue circle below)




Cut the link on JP7 shown below






While on the bottom solder a wire onto JP6





Back on the front, stick the chip in a suitable location



Install the JP6 wire on to the board along with the power wires. 5V can be sourced from L2 and ground from CE38





Now connect wires from JP10 & JP12 in area 1 to the relevant pads on the chip




Now we need to link the 50/60 wire from Area 4 to the board








Next we move on to the separate board with the reset button and controller ports




Remove the original LED




Turn to the bottom of the board and cut the track from the reset button




and solder a wire at each end on the track






Connect the 4 wires back to the chip, Sitting the boards back in to the case will doing this helps with wire lengths and routing






There is a convenient slot in the metal heat shield for the wires to fit




This is the modification complete, please fully assemble the console before testing as the PSU does have exposed high voltage components.
