Like the 49g+, the range of the infrared port has been limited to about 10 cm 4 inches.
#EMU48 WIKIPEDIA SERIAL#
In addition to all the features of the 49g+, the 50g also includes the full equation library found in the HP 48G series also available for the 49g+ with firmware 2.06 and above, as well as the periodic table library originally available as a plug-in card for the 48S series, as of firmware 2.15/ 2.16 the latest, as of 2015, and has a 3.3V TTL-level asynchronous serial port in addition to IrDA and USB Mini-B ports of the 49g+. The form and size of the calculator shell is identical to the 49g+ series, but four AAA batteries are used as opposed to three in previous models. A blue and white color scheme variant specifically tailored for high-contrast is available as well NW240AA. The back shell is textured more deeply than the 49g+ to provide a more secure grip. Using black plastic for the entire body, white, orange and yellow are used for function shift keys. The most apparent change is a revised color scheme, returning the unit to a more traditional HP calculator appearance. The HP 50g F2229A is the latest calculator in the 49/50 series. A port of the GNU C compiler is also available see HPGCC below. It is even possible to run programs written for the ARM processor thus bypassing the emulation layer completely. The speed increase over the HP 49G is around 3-7 times depending on the task. This allowed the 49g+ to maintain binary-level compatibility with most of the programs written for the HP 49G calculator, as well as source code-level compatibility with many written for the HP 48 series.ĭespite the emulation, the 49g+ was still much faster than any older model of HP calculator. The calculator system did not run directly on the new ARM processor, but rather on an emulation layer for the older Saturn processors found in previous HP calculators. This calculator featured an entirely new processor architecture, USB Mini-B and IrDA IrCOMM infrared communication, memory expansion via an SD SDSC/MMC card, and a slightly larger screen, as well as other improvements over the previous model. It was designed and manufactured by Kinpo Electronics for HP. Instead of the rubber keyboard found on the HP 49G, this calculators keyboard had plastic hinges intended to return the feel of older HP calculators, and also included a pouch to protect the unit, similar to those included with older HP models. This unit had metallic gold coloration and was backward compatible with the HP 49G. In August 2003, Hewlett-Packard released the hp 49g+ F2228A. Due to licensing restrictions, the recompiled firmware cannot be redistributed. In addition, this release included an interactive geometry program and some commands to allow compatibility with certain programs written for the newer 49g+ calculator.
#EMU48 WIKIPEDIA CODE#
In 2003, the CAS source code of the 49G firmware was released under the LGPL. Until at least firmware version 2.09, those emulator builds could be installed on the original HP 49G.
#EMU48 WIKIPEDIA SOFTWARE#
Several firmware versions for the successor hp 49g+ and HP 50g calculators have also been released in builds intended for PC emulation software that lacked full utilization of the successors ARM CPU.
#EMU48 WIKIPEDIA UPDATE#
The last officially supported firmware update for the 49G calculator was 1.18, but several unofficial firmware versions were released by the developers.
Almost the same hardware is also used by the HP 39G and HP 40G. In addition, it had a hard sliding case as opposed to the soft pouches supplied with the HP 48 series. The 49G was the first HP calculator to use flash memory and have an upgradable firmware. The 49G incorporated many of the most powerful interface and mathematics tools available on the HP 48 series into the firmware of the new 49G, including the ability to easily decompile and compile both SysRPL and Saturn assembly code on the unit. These changes were disliked by many traditional HP calculator users. In addition, it lacked a large ↵ Enter key which was seen by many as the defining characteristic of an HP calculator. In addition to having a metallic blue color, the keyboard material was rubber and did not have the traditional HP calculator hinged keyboard feel. Released in August 1999, the HP 49G F1633A, F1896A calculator was the first HP unit to break from the more traditional subdued coloration.
