HP 11C logo The Voyager series


The first calculators of the Voyager series were introduced in september 1981. It was the second HP calculator series using a LCD display. The small, thin screen combined with its low power consumption enabled the construction of a compact calculator, supplied by small button batteries. In total HP build five different Voyager models.

The two first introduced calculators were the scientific calculator, model HP-11C and the business calculator, model HP-12C.

Two year later the three additional models were added to the family. Two scientific models, the HP-10C, a cost down version of the HP-11C and the HP-15C, an improved version of the HP-11C with more memory were added. The third model, the HP-16C, is a dedicated calculator for computer programmers.

Since 2003 a more powerful version of the HP-12C is available. This model is called the HP-12C Platinum. It has a faster processor and more memory. Both models the HP-12C and the HP-12C Platinum are still in production.

On September 2011 a Limited Edition of the HP-15C was introduced. It has the same functionality as the original HP-15C but it is build around an ARM processor. This results in an increase in speed of more than 100 times.
