Schmartboards. A sort of clever electronic meccano set?

‘Schmartboards are pre-traced printed circuit boards that are connectable like building blocks. We call this patent pending product, “Electronic Circuit Building Blocks”. They allow one to build electronic circuits on a SchmartBoard block by block, and then connect the blocks together to form a functional board….Because the boards are pre-traced, the need for wire jumpers is minimized, as opposed to breadboards or wire-wrap boards.’
