Vintage graphing and scientific programmable calculator. HP 48SX sold with its original carrying case, without batteries or accessories.

TESTED AND 99% FUNCTIONAL, this calculator requires a bit of pressure between the screen and the keyboard (there is probably a weak contact in the ribbon cable going to the keyboard) for the keys to work properly. There are two vertical lines in the display on the far left (see photos). These minor issues do not prevent the hardware and software themselves from functioning correctly, it is probably an easy fix to get to 100% working condition. Super clean physical and visual condition, no corrosion in the battery compartment.

Hard to find, high-quality classic HP calculator.
