Dennert & Pape, the famous maker of the ARISTO slide rules entered in the year 1975 the market of scientific calculators. The design followed the M 36 four-function calculator introduced already in the year 1973. Thinner and slimmer than most other calculators e.g. a Texas Instruments SR-50 the ARISTO M 75 matched the appearance of traditional slide rules. 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.
