Hmm, I know this egg is NOT for fx-350ms... but I still tried it. There were two different things that happened when doing so: 1) The line where you enter the expression got filled by junk consisting of some weird functions (such as arg and a character resembling a hybrid of T and n) 2) The calculator went back to the normal mode, but I were now able to enter more than 80 x values into the list. This is really useful. However, the fx500ms-like effects such as the CMPLX mode didn't appear. What a shame. That's what I found out.

This works too in the Casio fx-115MS, with the same effects as described above (corrupted screen, normal mode, etc). It's probably a buffer overflow. Weird!
