Raytheon Lectron

Each building block was magnetically attached to a metal plate serving both as a work surface and ground, eliminating the need for soldering, spring terminals or a breadboard.

[1] The Lectron electronic blocks system and product was the exclusive and unique invention of Georg Greger in the early 1960s.

While the basic block design and the styrofoam storage case were retained, Dieter Rams and his team produced new outer packaging and a complete redesign of all manuals.

Dietrich Lubs, designer of the iconic "round button" pocket calculator ET66, created the symbols for several new Demonstrations-System elements (classroom system using oversize blocks) like the logic gates of box 1300.

[7] From 1967 until 1972, Italian company INELCO (Industria Elettronica Comense SrI, Tavernerio, Como) operated as local distributor for Braun.

From 1968 until 2001 INELCO provided translation for Braun and Lectron GmbH from German into seven languages (Danish, Dutch, English, Finnish, French, Italian and Swedish).

Raytheon also marketed a Series 3 model for Creative Playthings of Princeton, NJ which was sold as the 'S822 Lectron SCIII'.
