The System 1200 was designed by Mr. Horst Blum 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 printed exclusively in the A5 format.

The 1200 curriculum overview is presented below. Unfortunately, the curriculum was available only in German.
