Tx86 Series Cartridge Tape Subsystem Owner's Manual

This owner's manual for the Digital Equipment Corporation Tx86 Series Cartridge Tape Subsystem describes the TF86 (DSSI bus) and TZ86 (SCSI bus) models, primarily used for data backup and software loading.

Both models utilize the TK86 streaming tape drive, capable of storing up to 6.0 GB of data on a CompacTape III cartridge. The manual provides detailed operating procedures, including how to use indicators and controls, load and unload cartridges, utilize the write-protect switch, and perform maintenance like using the CleaningTape III (effective for approximately 20 uses).

A dedicated section addresses common errors, offering troubleshooting steps and emphasizing cartridge care, such as proper storage conditions and leader inspection, advising to contact Digital Services for hardware failures.

It extensively covers software interaction, detailing standard VMS commands (e.g., ALLOCATE, INITIALIZE, MOUNT, BACKUP, COPY) and offering specific guidelines for efficient operation, including recommended record sizes. For the TF86, it describes built-in ROM programs (PARAMS, DIRECT, HISTRY, DRVEXR, DRVTST) for diagnostics and configuration. For the TZ86 with ULTRIX, it explains setup (SCSI ID, kernel configuration, logical device names) and relevant ULTRIX tape commands (tar, dump, restore, dd, ltf, mt, cpio), highlighting the importance of block size for maximizing capacity and performance, especially noting a 2.1 GB file length limit on older ULTRIX versions.

Finally, the document includes technical specifications (e.g., 800 KB/s transfer rate, power consumption) and outlines various Digital Services support plans available to customers.
