third design of the TI-1706 looks at first glance
identical to the second design but deciphering the Date
codes suggests Inventec

Dismantling this featured TI-1706 calculator manufactured in March 1984 by Inventec Electronics in Taiwan reveals a clean design centered around a Sharp LI3129 single-chip calculator circuit soldered on a double-sided printed circuit board (PCB) and powered by five solar cells.
Inspecting the PCB of this TI-1706 calculator brought our attention to a small marks reading I1706-01K. We started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
Later calculators removed the "LIGHT POWERED" sign, don't miss the 4rd design of the TI-1706.
