Excerpt: The HP 49G series are Hewlett-Packard (HP) manufactured graphing calculators. They are the successors of the popular HP-48 series. There are four calculators in the 49 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. Because these calculators features CAS, none of the 49 series are permitted for use in the ACT, the PLAN and some classrooms, though it may be used on all of College Board's calculator-permitted tests, including the SAT, some SAT Subject Tests and the AP Calculus, Chemistry, Physics, and Statistics exams. Released in August 1999, this 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 sign 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 ROM. In addition, it had a hard sliding case as opposed to the soft pouches supplied with the HP-48 series. The last officially supported ROM update for this calculator was 1.18, but several unofficial ROMs were released by the developers. The final ROM version was 1.19-6. In 2003, the CAS source code of the 49G ROM was released under the LGPL. In addition, this release included an interactive geometry program and some commands to allow compatibility with certain programs written for the
