Hi there, does anyone know the self-test key combo for the Casio Fx9860GIII? I have an input/output error and my storage memory was full, so this is kind of a last ditch effort to try and save my calculator.

After this I might take it apart and yeah. Idk.

 

Many thanks!!

The key combo is OPTN [x10x] + [AC/ON] while the calculator is off, and then F1 9.

 

Your problem sounds like a flash read/write failure like my fx-9750GIII that was discovered 4 years ago. Check the "Characteristic" section to see if any one of them matches your situation:

I don't know how to respond directly to you; I am new, but thank you very much for replying! I will test this out. The only thing is that I do not know how to execute a syscall. Do I just type it in? Much appreciated, thanks!
Also how am I meant to add the C.Basic file if my storage memory is unchangeable? I will at least try it, thanks!!!!!
