The -2000 calculator combines the usual basic calculator functions with an Euro currency conversion. The exchange rate between the Euro and the Home currency is entered with the small SET-key. Two additional keys allow the conversion in both directions.

Dismantling this -2000 calculator manufactured in Summer 1999 by Nam Tail Electronics, Inc. in China reveals a standard design using a single-chip calculator circuit wire-bonded direct on the printed circuit board (PCB). This calculator got later a continuos memory and was sold as -2000+.

A more sophisticated approach could be found in thee -20011, this calculator got the 11 different exchange rates preprogrammed. If you need printing functions, view thee -20044.
