Hewlett Packard

Hewlett Packard, USA.

Hewlett Packard's first calculator was the 9100A electronic desktop model introduced in early 1968. It was a very advanced, scientific, programmable machine, taking magnetic cards and was priced at US$4,900.
Its HP-35, introduced in February 1972, was the first hand-held scientific calculator, and was the first in a series of highly specified hand-held calculators. These include the HP-80, the first hand-held calculator for business calculations, and the HP-65, the first programmable hand-held calculator.
