Texas Instruments TI-89 Titanium Graphing Calculator


je vend une calculatrice TI89 (les premieres) et son mode d'empois
elle fais tout ce dont on a besoin pour avoir une bonne note à ses exams
80 euros en mains propres sur paris

je vends aussi 2 calculettes HP 48 GX

an advice: ti 89 and ti 89 titanium are paractically identical, except for some minor component changes, but the normal ti 89 is a small bit cheaper, has (mostly) an older OS (but it can be updated to the latest version from Ti's website)
