first glance seems the TI-1776 almost identical with the TI-1766,
the first solar powered calculator introduced by Texas Instruments. The main
difference is a much smaller and thinner housing, engineers of Toshiba, Japan
shrinked the calculator in all three dimensions about 20%.
Disassembling the TI-1776 reveals a smart construction and a very clean layout. One of the tricks we noticed is a keyboard assembly with rubber keys instead the plastic molded keys of similiar calculators. The Toshiba T6789S single-chip calculator circuit was used in the 3rd version of the TI-1766 and the TI-1006.
