Batteries: | AA x 2 |

Introduced: ca. 1976 Terminated: unknown |
Notes: |
This is a very nice vintage calculator, and it only needs two AA
batteries. This calculator is quite slow, some operations really
take time, especially the trigonometric calculations; and trailing
zero's 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. I have no idea what D-ESR-E stands for! 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. |
