This unit is designed to replace instrumentation recorder for telemetry and
experimental data recording, not as a computer tape drive.  If used as
a computer peripheral, it has one serious flaw: it needs a MINIMUM data
input of 1 Megabyte/sec (and can handle up to 2M/sec per channel).
Honeywell said they would have a start-stop capable unit available "near
the end of 1988."
This also has a version that comes with manipulators and tape storage
carrells that offers Terabytes of "on-line" (that is, automated access)
storage.
