I have been able to backup data onto my audio DAT deck for the last 6 years on my NuBus PPC Macintosh with an audiomedia II digital audio card. I used this primarily for source digital audio file backups, but the program that digidesign inlcuded with their audiomedia II cards allows for you to backup 1GB of data onto a regular audio-only DAT tape, not bad for a $2 tape.
