The Curriculum Kybernetik II – Sensorik model was first listed in the Lectron – MW era 1974-OCT-01 price list. This was the complete standalone version of the Ausbausystem 4 model.

This model was designed by Mr. Edzard Timmer  the designer of the Kybernetik 1 curriculum that was first incorporated into the Braun Ausbausystem 2 M and its standalone counterpart.

The topic of this curriculum was sensors and what their biological equivalents were.

The sensors were also featured with the use of the vehicle introduced in the Kybernetik I curriculum.

I have never seen either of these models for sale on eBay since I began my acquisition of Lectron System models in 2012.
