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
• 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 Modern LCD-calculators outdated them due to their long battery life and thinner shape.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 silver trim 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.
