The ticket is combined with entry for the Palatine, so buy the ticket from the Palatine ticket offices.

Good news! The eccentric Roman validity system for the 1 euro tickets means that they are valid for all trips starting within 75 minutes. If the machine accepts your ticket only 1 minute before expiry, the ticket is confirmed valid on that vehicle or service even if your next leg goes well over the 75 mins. And if you think you are just over the limit, try anyway - many machines run slow.
