The
stylish TI-1000 series was introduced 1977 together with the TI-1025
and TI-1050 as a cheaper alternative to the
upcoming LCD-calculators. If someone counts generations on the early
TI-calculators, this one is from the third generation:
 | 1st generation: The famous Datamath alias TI-2500 |
| 2nd generation: The TI-1200 line |
| 3rd generation: The TI-1000 line |
Within one or two years after introduction of the TI-1000 the end of LED calculators was reached. Modern LCD-calculators outdated them due to their long battery life and thinner shape. Compare this LED calculator with the first TI LCD calculator, the TI-1750.
Please note that later models of the TI-1000 got a silvertrim
around the keyboard instead the earlier golden design. More differences could be
found inside the calculator !
Calculators with different nameplates were sold from Western Auto as Citation.
Don't miss the educational game "Spass mit Zahlen" based on the TI-1000.
