English: TI-59 programmable calculator with magnetic card reader (1977). A magnetic storage card is shown as it is put into the built-in card reader/writer via a slit on the right side of the device. The black plastic card below the display shows various mathematical functions from one (ML-11, "Triangle Solution (1)") of the built-in prestored standard software programs accessible through the function keys A-E. 25 such programs were pre-installed on an exchangeable module called solid-state software module (see Texas Instruments manual about the various modules, page 2.
Deutsch: Programmierbarer Taschenrechner TI-59 mit eingebautem Magnetkartenleser. Eine magnetische Speicherkarte wird gerade durch einen Schlitz an der rechten Seite in das eingebaute Lese-Gerät eingeführt. Die schwarze, entnehm- bzw. austauschbare Plastikkarte unter der Anzeige zeigt die Tastenbelegungen für eines der in einem auswechselbaren Modul ("Solid-State-Software") einprogrammierten Mathematikprogramme (Bezeichnung ML-11 "Triangle Solutions (1)"). Entsprechend der 25 mitgelieferten eingebauten Programme wurden 25 solche Plastikkarten mitgeliefert. Für einen Überblick über diese auswechselbaren Softwaremodule, siehe den damaligen Texas-Instruments-Prospekt, S. 2.
