Paul, you're absolutely right! The CMT module has been modified. The "LCIM" signal comes up from the PCB to pin 11. The blue wire is connected from pin 11 to a via next to a cut trace on the bottom side of the memory module. This is undoubtedly connected to the ID pin on the memory controller and the cut trace is likely VCC.

If anyone is interested in performing this mod I can provide a pic of the cut trace and via.

On an unrelated note, on which USB microscope did you settle?

Dave
