Vintage Gakken Denshi Block EX-100 Electronic Erector Educational Kit From Japan

Collector's Item.  Untested.

Excellent condition.  Box is missing lower layer.  Comes as seen in pictures.  

The Electronic Experimenter Kit EX-100 is part of the Gakken EX System, first released in 1976.  It consists of a selection of “Denshi” Blocks, a main unit in which circuits are built, and, if required, some additional external apparatus.  A Denshi block (or electronic block) is a small plastic box containing an electronic component which has conductive metal strips at their sides and a schematic sign labelled at the top.  The interconnects when placed in the gridlines of the main unit, so a configuration of blocks shows a schematic of the circuit.
