The original TI-106 was introduced already in 1989 and Texas Instruments released with the TI-106 II a very innovative successor for its 25th Anniversary. The two-line display borrowed from the TI-30X IIS allows the first time for a basic calculator to see input and answers the same time.

Dismantling this TI-106 II manufactured in November 2013 by Kinpo Electronics, Inc. in China reveals a typical design of a calculator developed in the 21th century. The single-chip calculator circuit is bonded directly to a high-quality printed circuit board (PCB) that connects with a flat ribbon cable to the LC-Display.

Don't miss the TI-Primaire Plus introduced a few month after the TI-106 II and the Canon Palmtronic MD-8 introducing the two-line display already in 1979.
