This TI-1746 looks with its stylish housing and the key design very familiar to us. If you compare it with the more common TI-1706 II you'll notice only an exchanged position of the solar cells and the LC-display. The reason is unknown.

Dismantling this TI-1746 manufactured in March 1985 by Inventec Corporation in Taiwan is not too exciting, the printed circuit board (PCB) looks like most PCBs of simple four-banger calculators developed in the 80s.

Inspecting the PCB of this TI-1746 calculator brought our attention to a small mark reading TI1746-01C, we spotted similar PCB-Marks already with the TI-1796 and TI-1798 manufactured in 1986. We started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.

Don't miss the rare TI-10 Profit Guide sporting a similar housing with a 10 digit display and some financial functions.

We recently discovered with the UNIS SLR 80 a rebadged TI-1746 sold in former Yugoslavia.
