(Germany) located company Dennert & Pape started already in the year 1872
the business with slide rules. About 100 years later they introduced under the
trademark ARISTO with the model M 27 their first electronic pocket calculator. • Version 1: Rectangular design, no CE key
As of today we know three different versions of the M 27 calculator, they can easily be differentiated by the shape and number of keys:
• Version 2: Rectangular design, red CE key
• Version 3: Rounded design, red CE key
The next calculator in the ARISTO line is the M 36 sporting an additional memory key. The M 36 could be called the most beautiful calculator and ARISTO kept this design for the next some twenty calculators.
• Version 1: Rectangular design, no CE key
