HP-49 Series - HP 50g

The HP 50g is the latest calculator in the "49" series. The most apparent change is a revised color scheme, returning the unit to a more traditional HP calculator appearance. Using black plastic for the entire body, white, orange and yellow are used for function shift keys. The back shell is textured more deeply than the 49g+ to provide a more secure grip. A blue color variant is available as well.

The form and size of the calculator shell is identical to the current 49g+ series, but four AAA batteries are used as opposed to three in previous models. In addition to all the features of the 49g+, the 50g also includes the full equation library found in the 48G series(also available for the 49g+ with ROM 2.06 and above), as well as the periodic table library originally available as a plug-in card for the 48S series, as of ROM 2.15, and has an asynchronous serial port in addition to IrDA and USB ports of the 49g+. Like the 49g+, the range of the infrared port has been limited to about 10 cm (4 inches).

The new asynchronous serial port is not a true RS-232 port as it uses different voltage levels and a non-standard connector. An external converter/adapter is required to interface with RS-232 equipment.

The keyboard, the most often criticized feature of the 49g+ calculators, uses the new design introduced on the very last 49g+ calculators to eliminate previous problems.

A worldwide announcement regarding the availability of this calculator was made by HP in September 2006, and official details are available on the HP calculators webpage.
