You are right about the Minneapolis complex...Mary Tyler Moore did live there!! It was built as a mixed development and then tended to become more geared toward lower income people and now is a huge mecca for immigrants.
On a side note...the architect behind the complex is Ralph Rapson, who is still alive today (age 92 and still practicing), is the chair of the Architecture Department at University of Minnesota and has the Architecture school named for him.
He did design the original Guthrie Theatre:
Which is being torn down soon to expand the sculpture gardens...
