I am fortunate to be able to present these graphics on Lectron.info due to the kindness of Mr. Gerd Kopperschmidt, the engineer behind all of the new Lectron models and the revamping of entire Lectron product line since 2001.
These two documents were faxed to Mr. Kopperschmidt in February of 2001 with the cover letter below.
Mr. Walter invited him to Didacta 2001 where Mr. Walter hoped to present the Digitaltechnick model to the public for the first time. Unfortunately, the model never went beyond conceptualization. This model became the idea for the 1007 Digitaltechnik model which was Mr. Kopperschmidt’s design.
