I've got the x48 HP 48 series calculator emulator running on my neo1973.
It was very easy to port - I just had to re-arange the screen layout a bit
to have it fit on a VGA window, and cross compile for the ARM CPU.

If you want a copy of this program, email orrery.moko at gmail.com,
and I'll mail it to you.
