The TI-1785, introduced together with 4 other members of the TI CARD family (TI-1783, TI-1784, TI-1786 and TI-1787), weights less than 1 ounce! It follows the TI-1780 calculator introduced about one year earlier.
A traditional sized calculator with similar dimensions was introduced with the TI-1606. A cheaper looking successor of the TI-1786 series could be found with the TI-307. Don't miss the colorful TI-1786 sold in Brazil by Mesbla.
Ten years later Texas Instruments sold with the TI-307+ still calculators with the size of a credit card.
Don't miss the Casio FIML CARD SL-800,
a real credit card sized calculator with a thickness of only 0.030".
