Restoring a Macintosh Backup

I have a tape that contains the backup of a Macintosh 8100. I have tried to use Retrospect to restore it but it doesn't recognize the tape as a valid format. I did a raw restore and the header does mention "Macintosh-BU1" and also "BackUp- 01.74" The tape was made in 1995. Anyone know what program I can use on my Mac to restore this tape? -Ken V. *************************************************************** This E-mail is confidential.
