Model: 1013
Type: Scientific calculator
Picture: GENESONIC 1013
Batteries: AA x 2
Lifetime: Introduced: ca. 1976
Terminated: unknown
Notes: This is a very vintage looking calculator, and it only needs two AA batteries. This calculator is quite slow, some operations really take time, especially the trigonometric calculations; and trailing zeroes in calculation results aren't displayed.

There are separate keys for the trigonometric functions and their inverse functions. These operations can be performed in degrees or radians, which is controlled by a switch.

The fluorescent display is oriented left-to-right, meaning that when you type a number the first digit shows up on the left side of the display, and following digits are appended at the right.

Same calculator as the privileg 883 D-ESR-E.


A power adapter.
