The 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.

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".

The TI CARD is featured in the Texas Instruments Incorporated bulletin CL-856 dated 1985.
