Info: ARISTO was a German slide-rule maker that entered the electronic calculator market in 1972.
The 1970s were a turning point: the company tried to adapt as pocket calculators replaced its established products.
ARISTO was the brand of DENNERT & PAPE, founded in Hamburg in 1862.
Its background was precision instruments, including slide rules for schools, universities, engineers and businesses.
Its first electronic calculator, the M27, appeared in autumn 1972.
ARISTO had acquired the rights to a design created by BENTERT Hilmar for LUTHER-ELEKTRONIK.
It used a Texas Instruments calculator chip and initially cost 466 Deutsche Marks.
The name ‘27’ reversed the digits of its launch year, ‘72’
In autumn 1973, ARISTO introduced the M64, its own design using a GENERAL INSTRUMENT chip.
An interesting detail is how cautiously ARISTO initially presented the new technology.
In 1973, it called the calculator ‘a genuine partner to the slide rule’.
Its literature still promoted slide rules for quick estimates while acknowledging calculators’ advantages in addition, subtraction, accuracy and decimal placement.
That shows a company trying to introduce electronics while preserving its existing market.
The calculator range focused heavily on education, extending from basic arithmetic to business and scientific calculations, without freely programmable models.
The transition was short-lived: slide-rule production ended in 1978, and ARISTO ended its electronic calculator production in early 1979.
Its calculators therefore belong to a brief, distinctive chapter in German computing history.
