I have Time Machine backups from my iMac Early 2008 (20"). Can I determine from those backups what OS X version was running on the machine at the time of latest backup?

Best Answer
Just open the file
to determine the product version ("latest" is a sym-link).
BackupName.ext, BackupVolumeName, ComputerName and VolumeName are all variable and depend on the type of backup or the names configured/given to your backup volume, Mac and main system volume. BackupName.ext is often Backups.backupdb though.
Here is my SystemVersion.plist (it's the original file and not a file in a backup) opened in PlistEdit Pro. You may also open it with an arbitrary text editor or Xcode:
