Old TV Broadcast of MN State Tourney GAme

Interesting link here as this a 1979 Minnesota Boys State Tourney game. What rule differences do you notice(besides jump balls) and mechanics used as compared to today(2 man). Also when did HS rules go from the lane on a free throw hitting the rim to release(the 1st time). Also I'm not sure why there was a 3 point line on the floor. The NBA didn't have it at the time and of course neither did high school or college. Only thing I can think off is that the building bought a floor and hosted some ABA exhibition games when it 1st opened and they never got rid of it. Here is the said link.
