There was no block or content difference between the Lectron, GmbH – MW era and Braun 1200 model.

The 1200 model was designed to acquaint the student with the ‘axioms’ of switching (logic) algebra and Boolean algebra. 16 Boolean functions are explored derived from the two binary variables of 0 and 1.

The System 1200 was accompanied with the Lehr-und Lernkartei (teaching and learning cards) documentation set and was available exclusively in the A 5 format and only in German.
