Trac Moped

I'm going to guess a moped goes in this dept. I have this really old (probably 70's) Trac Moped with a Daelim Motor on it and I know absolutely nothing about it. Do you think it would be worth to restore and do you know where I can get more information about it? I bought this before my first car for $15. Nice Bike.
