This is the Sparcom Celestial Navigation Pac based on the celnav.lib by the original author. The package contains a dump of the original card for use in HP 48 emulators or on a memory card, the port of the software to the 49/50 as a library, and the scanned manual as a PDF. The dump is compatible with the 48SX/48GX; the library is compatible with the 49g+/50g. Redistributed with the permission of the family of Dr. Thomas Metcalf.
This is a modified version of the Sparcom Celestial Navigation Pac, patched to work on the 49/50 and virtual machines. It includes these improvements: better display formatting, ADV program now reaches the expected result and it can run on real or virtual machines.
Emulator of the newer Hewlett-Packard handheld calculator models with an ARM CPU (HP 49g+ and HP 50g). This is a true ARM emulator running on Unix, Linux, and MacOS Systems. Porting to Windows should be easy as the GUI is based on GTK+. The project is still in alpha state; you can find updates at http://x49gp.sourceforge.net/ or https://github.com/claudiobsd/x49gp.
