Thanks to the HP-15C LE code writer, who implemented enough RAM registers, not only the original 64 registers.

And also thanks to Eric Smith, who extracted the 15C ROM image long ago, without him there would be no HP-15C LE. Yes there is an indubitable proof that the 15C LE uses the ROM from nonpareil.
I will not disclose more about it, you can try to find the proof by yourself, but be warned that it's a tough challenge!

Maybe Eric will someday comment and maybe tell us more about the HP-15C LE story.
After all, this is history now, HP is no more in the calculator business and a re-introduction of this machine by the HP licensee is unlikely.
