This emulator is heavily based on earlier work by Francois Roulet (http://home.citycable.ch/pierrefleur/HP65/default.htm).
That work also derives from others as credited on his site.
Whilst the Gss-HP65 emulator is based on the work of others, it has been modified and earlier contributors neither endorse this version nor are responsible for any bugs in it.
License
Francois’ work is published as CC-SA-BY.
Much of the earlier work has been released under versions of the GNU General Public Licence. Both licences are stated to be compatible.
