Dacta was an original LEGO theme from 1960 to 2003 that deals with all things that can be used with educational facilities, such as DUPLO and TECHNIC. Dacta was later replaced by the LEGO Education theme. Sets in the Dacta product line were exclusively developed for usage in younger aged schools so the sets typically contain a large amount of pieces for playing and learning in groups. The sets were designed to contain a higher number of bricks and elements at a lower cost.
1980 LEGO Sets
1980 refreshed the 12V Train system with remote-controlled points, signals, lighting, and decouplers, creating one of LEGO’s most sophisticated play ecosystems. Classic Space continued its rapid growth with larger craft, bases, and color-varied astronauts. Expert Builder (the forerunner to Technic) advanced functional builds with more gears and linkages, while LEGO Dacta was established to bring learning-through-play into classrooms.
