HP 39GII newly added to my collection
The HP 39gII (NW249AA) was released in October 2011. It is built around an 80 MHz Freescale (formerly SigmaTel) STMP3770 processor with ARM926EJ-S core and features 256 KB RAM and 128 MB flash memory (of which ca. 240 KB RAM and 80-105 MB flash are available to users). The high-resolution monochrome gray-scale LCD provides 256×128 pixels. Connectivity is provided through a USB-OTG Micro-AB connector. The BCD math libraries internally used by the #calculator were rewritten in platform-independent C code run natively rather than System RPL code executed in an emulator. The Pascal-like programming language supported by the calculator is a predecessor of the #HP Prime’s HP PPL. The #calculator is the first to support Unicode (UTF-16).
