Main difference are the position of the Memory and Error indicators on the display and the printing on the housing. Don't miss the 2nd design of the TI-1706.

A more attractive design was introduced with the TI-1767, the housing of the TI-1780 featured the size of a credit card.

Compare some other TI calculators with their siblings manufactured by Toshiba.

In Germany the TI-1706 was sold as an educational toy called "Rechen-Spiel und Rechen-Spass" together with a funny booklet based on Walt Disney's creatures. 
Don't miss the real Mickey Mouse calculator.
