The HP-80 was HP's second handheld electronic calculator and its first business model. |
The first pocket-size business calculator, the HP-80 was introduced
following the success of the HP-35 handheld scientific calculator.
This product shared many features of the HP-35 but was geared toward
business users as opposed to scientific and technical customers.
A desktop printing version, called the HP-81, was also made available.
