(760 was a restart attempt that failed)

Several of them look like they dropped out for a couple of years before returning to FIRST. No telling who may have split up into other legacy teams.
So 11 of the original teams are still with us. I don't imagine too many original members (mentors and students who are now mentors) are still with us, but I bet there are a few. Who are you?

As I recall, there are either 7 or 9 legacy teams that get a pass to Championships. I think they're the ones that have been continuously active.
