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.
