This is an amazing Lego Dacta Mindstorms Kit from the 1990's- set 9780 ( 9780-1 and 9780-2).  It contains 2 large green storage containers with inner removable plastic dividers and all Lego bricks.  The set label says it contains 1615 pieces.  I have printed out and included the Bricklink inventory for pieces included in the set and all the bricks and minifigures are there.  I did not count the small black rubber bands (although there are a lot there), because some may break easily because of age.  You may need to replace some of those.  Also, some of the electrical wires may not work or be frayed due to age.  The set did not originally come with an RCX brick, but one is included.  I do not know how many instruction manuals originally came with the set, but 4 are included.  This would be a wonderful addition to a Robotics team or enthusiast as this set is rare and difficult to find.  Thanks for looking!
