according to the diagram, the point "S" is at the bottom side. when i open my ps2 v1, look at the board, turn it upside down but i can't see the point "S" as indicated in the diagram. in fact, it's not really a bottom side, it's a double-board connecting to each other by the four big soldering-points.
should i de-solder these 4 points to separate the two boards?
where is the "S"?
thanks for your help.
