Merging contacts from old Mac to new iPhone

[MartinTravels]

I have an old PowerPC mac running OS 10.5.8 and a new iPhone 5s.

I have contacts on the Mac in Address Book, and different contacts on the iPhone.

I would like to merge these two different contact lists to make one master contact list. Is this possible? There are hundreds of contacts, so manually entering them does not sound very appealing. Any help would be greatly appreciated!

It would be possible if you could use iCloud since the contact lists would auto sync. Sorry but I don't know of an easy way you can do it with your PPC Mac running Leopard.

I do use iCloud, and it is synced with the iPhone contacts. But no iCloud for the PPC, although there was a way to export on the Mac with the now defunct MobileMe. At this point, I know there is no easy solution. I'm just hoping that there is a solution.
