A logic training board assembly, mountable on a base, for receiving in an orderly way electronic elements such as DIP IC\s, comprising: a plurality of power distribution strips each of which has a plurality of first circular terminal slots; a plurality of element terminal plates each of which has two parallel longer sides and two parallel shorter sides and each of which has a plurality of second circular terminal slots arranged in intersecting rows, first grooves of V-shaped cross-section extending on the surface of said plates parallel with said shorter sides, each of said shorter sides having a bevel face adjacent to the top surface of said plate, said bevel face of one of said plates cooperating with said bevel face of another adjacent plate to define a second groove which is the same size and shape as said first grooves, wherein said terminal slots located along the border of said second grooves are at the same distance from each other as, and located in the same rows as, said terminal slots located along the border of said first grooves on the surface of said element terminal plates, which distance corresponds to the distance between opposite pins of said DIP IC; means for connecting said strips and said plates in a side by side relationship, including dovetail protrusions and dovetail recesses provided at the sides of said strips and said plates; and means for mounting said strips and said plates on said base, including concealed threaded holes adapted for receiving a screw at the bottom side of said strips and said plates.
