In France, the fx-9860GII is called "Graph 75", and the fx-9860GII SD is called "Graph 95".
For back to school 2014, we got a new model, the "Graph 75+".
It was just a "Graph 75" coming with OS 2.04 and the SH4 CPU.
For back to scool 2015, we're getting a new model again, the "Graph 75+E", coming with a new 2.05 OS :
It features a new "exam mode", and an exam LED.
Activating the "exam mode" does turn on the LED, and forbid you from running add-ins.
To activate the "exam mode", you need to turn on the calculator while holding [cos] and [7].
The test menu does reveal a new "CY802A" code and OS 2.05 build date.
It seems the model is still using an old boot code built in 2011 though.
And at last, here is the new 'CY902-1' PCB :
