Brand: MBO
Model: EXAKT 30
Type: Almost scientific calculator
Picture: MBO EXAKT 30
Batteries: AA x 1
Lifetime: Introduced: ca. 1979
Terminated: unknown
Notes: Not entirely sure how to classify this, it's not quite a scientific calculator but it's not a basic calculator either because it has squares, reciprocals, roots and π.

This calculator as a fluorescent display but operates upon a single AA battery.

Next to the four basic functions it has a memory, percentages, and some scientific functions. It also has a "π"-key but lacks the trigonometric functions. The constant π however can still be very useful for calculations upon circles and spheres and their derivatives.


A power adapter (MBO-BV 116).
