DS-HPCALC is a project to port the Nonpareil calculator emulators, originally written by Eric Smith, to the Nintendo DS Lite.
HP11C.NDS emulates the Hewlett Packard HP-11C;
HP16C.NDS emulates the Hewlett Packard HP-16C, both fully programmable, programmers calculator with persistent memory.
The first time you "turn the calculator on" it will display "Pr Error". This is normal behaviour and indicates that the persistent memory has not been initialised yet.
The calculators maintains their persistent memory in a file on your loader. Memory is only written to the file when the power button on the calculator is pressed to turn the calculator "virtually" off.
Most of the underpinnings of the calculators is provided by the Woopsi User Interface library, which can also be found on SourceForge.
Thanks go to SourceForge for their support of open source programmers, their provision of such a valuable resource and their speedy response to all my queries.
