Software side

Features

The CAS is based on the open-source XCas engine, an powerful and advanced one, made to operate more like Maple, MATLAB, Mathematica, as opposed to something like the Nspire's CAS, which is made to be easy.[1]

OS version history

  • Pre-releases versions (from leak(s) and testers) : from rev. 3xxx to 4980

Hardware Revisions

Programming

About half of the RAM is taken up by the OS, the other half is free.[1]

HP-Basic

Lists are array pointers.[1] Objects work through reference counters. You can have a single object reference in many places - it could be hardcoded in the main memory, or a user object on the home screen, or a variable.[1] All characters are UTF16.[1] Once exported, functions act like they are built in. The advanced grapher uses interval based math, and cannot be mixed with user functions.[1]

Native

No native programming capabilities are offered by default.

Emulation

HP Provides a free Windows software (runs correctly in Wine on other platforms) reproducing the handheld behaviour. It is not a emulator, but a simulator (the codebase has been recompiled for Windows). It's estimated to run between 5 and 10 times faster than the handheld depending on the application.
