TI-1000G_P1.jpg (275492 Byte)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 Modern LCD-calculators outdated them due to their long battery life and thinner shape.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.

Calculators with different nameplates were sold from Western Auto as Citation.
