The beautiful ARISTO M 36 was introduced by Hamburg (Germany) located company Dennert & Pape in the year 1973 and followed their first calculator M 27. The housing was longer but thinner and both size and appearance matched the traditional slide rules. Dennert & Pape kept the design even with their first scientific calculator, the M 75 introduced in the year 1975.

German competitor Faber-Castell took a similar design approach but added even a traditional slide rule on the back of the TR1 electronic pocket calculator.
