Description from the seller
Splendido lotto da collezione vintage: Texas Instruments TI-58 programmable calculator, manufactured starting in 1977. A true piece of electronic computing history. This lot is exceptionally complete with all its original accessories, a very rare detail to find today: Original box from the era in good condition. Original protective leatherette case. Original power supply/charger. Original memory module "Master Library Module" installed inside. Condition: The calculator powers on regularly, and the red LED display is bright and perfectly readable.
