HP Calculators pays homage to legendary HP-35

As part of its 35th anniversary in the handheld calculator business, HP launched the HP 35s scientific calculator - a retro-designed device reminiscent of the legendary HP-35 and is targeted for science and engineering students. Back in 1972, the HP-35 was the world’s first handheld scientific calculator and revolutionized the market by virtually displacing the then-ubiquitous slide rule. Today, the new HP 35s is HP’s most advanced scientific programmable calculator.
