The TI-1650
and its siblings
TI-1600, TI-1680 were very flat calculators compared to the previous TI-1200
models. Only one year in front of the first pocket-sized LCD-calculators
you could carry them in your shirt.
Dismantling
the TI-1600 or one of its siblings is difficult, three small plastic locks have
to be bent together in different directions.
The technology behind the
TI-1650 is similar to the TI-1265,
instead of the normal 9V battery a very flat (custom made by French company
SAFT) rechargeable battery is used.
Sales figures kept low, soon after the introduction of the TI-1650 the first LCD-calculators appeared on the market.
