Address Book - Lost a bunch of contact info during "Merge"

Trying to “Bluetooth” contacts to my new phone and struggling a bit. Tried a few options with no luck, so I highlighted all contacts then clicked “MERGE CARDS”. This put all phone numbers under the “Apple Computer” contact, (I think it was the top of the list alphabetically), and wiped out all other information from my one hundred plus contacts. I then went to “EDIT” and clicked “UNDO MERGE”, and now the pinwheel has been spinning for about 4 days. I really need to recover my contacts and could use a little help. Anybody?
Thanks in advance,
Brian

Using Time machine? Since it backs up your address book contacts as well.

Under "computer name"/Library/Application Support/Addressbook

Problem solved...

No time machine on this machine

Negative on the time machine. Any ideas on how to recover the contacts without time machine?
