TI-1766 II introduced in 1988 and replacing the short-lived second design of
the TI-1706 II looks almost identical to the
original TI-1766 II introduced in 1986. A closer
look reveals a great surprise: The [AC] key was replaced with a [+/-] key.
This third design of the TI-1766 II was manufactured both in Taiwan and Malaysia, we assume that production was shifted around 1990 based on the © information located on the rear of the respective sales boxes.
Dismantling this TI-1766 II manufactured in September 1990 by Inventec Corporation in Malaysia reveals a clean design centered around a Toshiba T9731BU single-chip calculator circuit soldered on a double-sided printed circuit board (PCB) and powered by four small solar cell.
The third generation of the TI-1766 and TI-1706 - named TI-1766 III and TI-1706 III - wiped out the exclusive flair of the TI-1766 and used similar housings.
The TI-1766+ introduced in 1996 brought finally the value proposition of the TI-1766 series back again.
