Applications
The Tandberg TDC 3300 Series tape drives were widely deployed in the 1980s and 1990s as internal backup solutions for business and industrial computer systems, including midrange and departmental platforms such as the MAI Basic Four business computing systems. These drives provided reliable streaming tape backup in environments where data archiving and sequential backup to tape cartridge was the standard method. Today, TDC 3300 Series units are sought by legacy system maintainers, collectors of vintage computing hardware, and organizations still operating MAI Basic Four or compatible equipment that requires period-correct internal tape backup drives.
