SX-64 Reset modification

While opening one of my SX-64 executive machines i happen to notice this reset modification. Actually i already suspected some modification was done as the reset button on the front, which normally only does a IEC device reset, acts also as a system reset. The J3 connector is disconnected from the P22 “Reset” pins from the IEC board and direct connected to the ‘blue and grey’ modification cable. It works perfectly!
