Is there a version of MicroWorlds that allows programing for a Lego Robot? What version? What is needed for the interface between computer (Mac) and the robot? And where can that be purchased? When I Googled for Lego/Logo, there were 353,000 sites - 27,000 in English.!!!! "Zoom" on PBS is currently featuring lego/logo. Thanks Kate Mikula Finally - of Austin, Texas
