The Olympia CD 80 / Panasonic JE-850U is a slightly earlier model without the memory function.

A fantastic calculator - it exudes style and quality.

Panasonic made a whole family of calculators with similar style features. The later ones are small-sized pocket calculators, but these early ones with their large size look the most stylish.

This model has many high quality (and so expensive features) -

• The keyboard uses reed-switches activated by magnets on the keys. Being sealed these switches are ultra-reliable having long lives and giving few contact bounce problems.
• The circuit board and the display are plug-in modules, allowing quick and easy servicing (if necessary).
• A choice of power source by the use of clip on power packs.
• Even the recharging unit has its own soft carry case too !
