Bruno Sonderegger had a Coragraph DC 2 at his disposal which is a computer-controlled drawing system with two plotters,
the precision coordinate tables 1600, which are often supplemented with the speed plotting board 1100.
This modular system is used for the optimisation and rationalisation of graphic working requirements in the field of geometric data processing. For this reason, Sonderegger’s graphics are also examples for the application of the Coragraph DC 2.
