This veteran tape drive is still performing its function
in the real world. This was the first DLT tape drive with
unique, tape loadable firmware that allowed easy updates to
the drive's microcode, so that additional capabilities could
be added by merely changing software. The same technique also
permitted customization to the SCSI interface parameters.
Also notable was the fact that the DLT 2000XT used advanced
linear recording technology, a precision tape guiding system,
and an adaptive control mechanism, all of which were retained
in future generations of DLT tape drives.
