?? quickie Diffs on main rules Fed vs ASA

[1231234]

I know it has been dealt with in the past. Not sure on what site. Any "quickie" diffs between Fed Rules & ASA other than the feet on the rubber/ pitching.
I know there are many small diffs but which ones are most likely to happen normally in a game re: differences?
Just finished Fed rules this past week & little time to chk ASA Book RE: 2005's rules & main Fed diffs. Help!
