Olivetti LOGOS 9 - Computer - with cover

In 1980, the Olivetti Logos 9 printing calculator was a major technological breakthrough. Though just a bit larger than a cigarette pack, the Logos 9 had advanced features making it the most sophisticated compact printing calculator in the world at the time.

The Olivetti Logos 9 introduced several innovative design features. It had a sliding top that exposed a precise printing head for printing clear letters and numbers. The printing head did not require ink cartridges, instead using thermographic paper that produced sharp images when struck.

Unable to test the calculator because the battery does not charge.
