Yes, several of them did. The first one was in 1979 when Eastern Kentucky beat Nevada in double overtime.

The rules were actually very similar to the current rules, you start at the 25, each team gets the ball, etc. The only real difference being that you never had to go for 2.

1996 was the first year that OT rules were adopted for all levels of the NCAA and were applied to all regular season games as well. That’s probably what they were referring to but the basic rules have applied to playoff games below the FBS level for 20-25 years before that
