The HP-11C (Voyager 1.0)
Introduced on the 1st of september 1981, discontinued end of 1988
A scientific, programmable calculator with hyperbolic functions and a random generator. Thanks to the compact size, battery lifetime and quality this calculator was a big success.
One of my favorite calculators.
