Compared with the later "Cheapos" this TI-5112 feels very strong and solid. It features everything you need for the daily use on your desktop.
cheaper model was available almost three years later as TI-5020
and it took another year and the TI-5100 II upgraded
the LC-Display to a green fluorescent
Dismantling the TI-5112 reveals a clean design based on the Toshiba T6736S single-chip calculator circuit but hides the true manufacturer of the calculator. We suspect Toshiba based on the layout and appearance of the printed circuit board (PCB) but can't proof it.
