• Notes
• 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. They interconnects when placed in the gridlines of the main unit, so a configuration of blocks shows a schematic of the circuit.
