I have bought a 15C LE. But I am not very happy with it. Self test is not working in correct way. It doesnt matter, if calculation is okay. But today I found ot, that the programm "Display Format Control" (you can find it in the actual handbook and also in that one from the 80s)does not work correctly. The steps from 9....0 are not shown correctly. After starting you see "0" after some sec only.
The old calculators are running correctly. Also the emu on my iPhone 4s.
In my opinion the 15C LE is a "Made in China" product. If you like this calculator type, try to get one made in the 80s.
Kind regards
