The TI-1103 was introduced in the year 1986 together with the TI-1104. Both calculators based on the simple design of the TI-1100 II. The TI-1103 was available in two colors, blue and red. View the other one here.

Dismantling this TI-1103 manufactured in August 1993 by Inventec Corporation in Taiwan reveals a pretty simple internal construction centered around a single-chip calculator circuit. Please notice that production of the TI-1103 was shifted around 1989 from Taiwan to Malaysia.

If you prefer the AOS system, view the MathMate, if you like solar cells view the TI-1105 and the TI-108.

Three years later TI created again a very stylish calculator, view the TI-701.

A similar technology could be found in the Creeks N' Creeks.
