It features a 3.5", 16-bit color, multi-touch, TFT screen with a 320x240px resolution.

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.

OS version history

Hardware Revisions

• Early / First (known) revisions (prototype):

• The calculator was named "HP Advanced Graphing Calculator"
• The back color is white
• The D-Pad was silver-colored

• DVT Prototypes:

• The calculator gets the name "HP Prime Graphing Calculator"
• The D-Pad gets black-colored

• Production models :

• The calculator gets its back color changed to Black.

Programming

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

HP-Basic

• Very compatible with the HP 39Gii's BASIC. (mostly additions and fixes)
• Lists are array pointers.
• 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.
• All characters are UTF16.
• Once exported, functions act like they are built in.
• The advanced grapher uses interval based math, and cannot be mixed with user functions.

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.
