CASIO CLASSWIZ fx-991SP X Iberia

[jebem]

Looking into some Japanese and Chinese photos published one year ago in some other forums, I realized that this calculator can display the firmware version like their older siblings like the fx-991ES for instance.

I tried the older models self test procedure and it works here with a few differences.

Self test 1:
Power off the calculator.
Press "Shift" + "7" + "ON"
Press 9
Press "Shift" to scroll thru the different tests.
Press "ON" to reset.

My Iberia machine shows "CY-255 VerA".
I think this could be the firmware version for the SP X Iberia model.

Can anyone test the other variants and publish the results?




Self test2:
Power off the calculator.
Press "Shift" + "7" + "ON"
Press 8
Press the keys indicated by square brackets.
Press "ON" to reset.
