I've removed most of the standard C startup code to save flash space. Details are in the linker control file and the ARM assembly startup module.

Volatile RAM is lost after each single keystroke. To save state between keystrokes you will need to put the information in non volatile RAM. As Pauli indicated, the LCD buffer is used to save some state while the calculator is idle but not turned off. The block is named StateWhileOn. I'm pretty sure it is exhausted.
