When did in-game dunking become legal?

[amusedofficial]

The no-dunk rule was added because a kid named Alcindor at Power Memorial in New York changed the way they played the game

The raise-your-hand rule was sometimes manipulated by having a player raise his hand to try to take a foul called on someone in foul trouble. It rarely worked.

Adding a shot clock does not mean buying new scoreboards. Shot clock timers can be retrofitted to the facility and are in many locations where shot clock rules were added. It can be a timer under the basket or against the gym wall or next to the scoreboard. In many schools with one scoreboard, the home team picks its bench so it will face the scoreboard, and thus the clock, during the last period, so everyone isn't getting a clear look at the time at all times anyway.

Can we bring back the hand paddles for team and player fouls? NO? OK.
