TK85 Tape Drive Reference Card

This document is a quick reference operator's card for the Digital Tx85 tape drive. It outlines the drive's front panel components, describes the power-on self-test (POST) sequence, and provides an indicator summary explaining various operating conditions (e.g., tape in use, write protected, cleaning required, or fault). The card includes step-by-step instructions for loading and unloading tape cartridges, along with general operating hints and troubleshooting advice (e.g., when to use a cleaning tape). Additionally, it details cartridge compatibility, noting the Tx85 drive can read multiple tape formats (Tx85, TK70, TK50, TZ30) but can only write in Tx85 format on CompacTape III cartridges.
