I had a Mac Powerbook, purchased in 1999, I think OS 9.1 was the last it ran, and it died several years ago. I just rescued the data, including my old Eudora mailboxes, and would like to import them into my current Thunderbird. The files have names like "In" or "._Out" - no suffixes, and Windows doesn't recognize the types of files they are. Suggestions please, on what to do with these files, and with Thunderbird, to perhaps make some of them readable?
