The
TI-1788 III combines the clock and stopwatch function
known from the TI-1788 II with a
currency rate calculator. Compared with the TI-1790
introduced about 6 years earlier size and weight was reduced dramatically.
Dismantling
the TI-1788 III reveals a single-chip calculator circuit supported only by the
display and a small buzzer for the alarm. We know the Toshiba T6798S already
from the Canon LC-64T.
The
TI-1788 III provides in the pouch even a small table to calculate the time in 19
other time zones.
