The HP 49/50 series are Hewlett-Packard (HP) manufactured graphing calculators. They are the successors of the popular HP 48 series.

There are five calculators in the 49/50 series of HP graphing calculators. These calculators have both algebraic and RPN entry modes, and can perform numeric and symbolic calculations using the built-in Computer Algebra System (CAS), which is an improved ALG48 and Erable combination from the HP 48 series.

Released in August 1999, the HP 49G (F1633A, F1896A) calculator was the first HP unit to break from the more traditional subdued coloration. In addition to having a metallic blue color, the keyboard material was rubber and did not have the traditional HP calculator hinged keyboard feel. In addition, it lacked a large ↵ Enter key which was seen by many as the defining characteristic of an HP calculator. These changes were disliked by many traditional HP calculator users.

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.

The 49G was the first HP calculator to use flash memory and have an upgradable firmware. In addition, it had a hard sliding case as opposed to the soft pouches supplied with the HP 48 series. Almost the same hardware is also used by the HP 39G and HP 40G.
