Product Description
===================
The TZ86 series of cartridge tape subsystems are used primarily as backup
storage devices and as devices for loading software onto Digital computer
systems. The TZ86 comes embedded in a system enclosure or in a tabletop
enclosure with its own power supply. The TZ86 drive is a streaming tape
drive that can store up to 6.0 gigabytes of data on a CompacTape III
cartridge.
