This UNIS SLR 80 manufactured in the Eighties in Yugoslavia is obviously a 100% copy of the TI-1746.

Dismantling the SLR 80 reveals indeed a printed circuit board (PCB) with even the TI-1746 designation, we assume that the calculator was assembled by UNIS in Yugoslavia based on parts supplied by Inventec Corporation in Taiwan.

We started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
