Description
1979 the miniaturisation of pocket calculators was so far advanced, that
it was possible to integrate even an astrological minicomputer into a small
pocket calculator. This astrological computer was able to calculate the properties
of your zodiac sign by your birth date and compare it with those data of other persons.

Visually, the Kosmos astro looks much like an ordinary pocket calculator,
only eight LEDs (in pairs of yellow and green) indicate the additional feature.

Inside, you find besides the familiar components such as CPU, display,
resistors for the VFD and a high voltage coil some other discrete elements like
transistors, diodes and resistors, which were no longer ususal that time, but had
to be used for driving the eight "astrological" LEDs.

The calculating power is standard, only the four basic types of calculations
are possible; a division by zero simply returns zero instead of an error. There's no memory
and no constants function; overflow errors are indicated by an "E" on the ninth position.
