TI-1786, introduced together with 4 other members of the TI CARD family
(TI-1783, TI-1784, TI-1785 and TI-1787), weights less than 1 ounce. It followed
the TI-1780 calculator introduced about one year
earlier. Don't miss the colorful
TI-1786 sold in Brazil by Mesbla.
The TI-1786 was even used as a promotional product, compare the backside of a standard TI-1786 and an ESSO branded calculator.
Does this TI-1786 look familiar to you? Please compare it with the Technico F-1 ExecuCard calculator manufactured by Inventa Electronics Corporation of Taiwan.
A traditional sized calculator with similar dimensions was introduced with the TI-1606. A cheaper looking successor of the TI-1786 could be found with the TI-307.
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".
