This TI-1006 introduced late in the year 1982 seems to be identical with the Toshiba HB-103. The printed circuit board (PCB) carries not only a calculator chip manufactured by Toshiba, the Toshiba brand is etched into the copper of the board.

The odd keyspacing of both calculators was corrected with the TI-1706 intoduced one year later. Please notice on the right picture the different size of the TI-1006 and its successor. This proofs the TI-1706 isn't just a stylish variation of the TI-1006, it's a complete different product.

We assume that the first production batch of the TI-1006 used a slightly different design and solar cells. The pictured calculator on the right states "BATTERY FREE" and seems to have solar cells with 10 small elements. We know similiar changes from the early TI-1766.

Later boxes showed smaller solar cells and stated "LIGHT POWERED" close to the type designation.

Compare some other TI calculators with their sibblings manufactured by Toshiba.
