History
Originally named ALGB in 1993, it was developed by the French mathematician Bernard Parisse for the HP 48SX. Over time, the system integrated a lot of functionality from another math pack for the HP 48 series, ALG48 by Mika Heiskanen and Claude-Nicolas Fiechter. At some point, ALGB was renamed into Erable, a French play-on-words on another CAS named Maple. Compatible with the HP 48S, 48SX, 48G, 48G+, 48GX, Erable became one of the "must-have" software packages to be installed by advanced users of these calculators.
When Hewlett-Packard developed the HP 49G in 1999, the Erable and ALG48 packages became an integral part of the calculator's firmware, now just named HP49 CAS.[1]
As HP CAS it also showed up in the HP 40G,[2][3] 40gs,[1] 49g+, 48gII and 50g[1] and was maintained by Parisse up to 2006.
Based on his experiences with Erable, Parisse started developing a new and more general CAS system named Xcas / Giac in 2000. It is written in C++ rather than System RPL. This system was integrated into the HP Prime in 2013 under a dual-license scheme.[1]
Versions
The last stable stand-alone version of Erable for the HP 48 series is 3.024 (1998-08-06),[4] with source code as of 1998-07-14 available under the GNU GPL.[5] The latest beta versions for these calculators are 3.117 (1998-10-17)[6] and 3.201 (1999-02-07).[7]
Parts of the CAS system for the HP 49/50 series (version 4) were released as open-source under the LGPL (since some parts of the CAS, which are copyrighted by Hewlett-Packard, remain proprietary software) and were maintained by Parisse up to 2006-02-02 (for firmware 2.14),[8] and 2006-09-19 (for firmware 2.15 (2009-04-21)[9] and 2.16 (2012-04-26)).
