The demonstration model 3201 was the equivalent to the System 1200 model but used the large 81mm x 81mm blocks.

This model substituted a separating block in place of the meter block. The LN 300 9V dc power supply was also included. The Schaltalgebra 1200 A5 format Lehr-und Lernkartei (teaching and learning cards) documentation was also included and the model was delivered in six cassettes using three metal stacking trays.
