 +====== Compatible SCSI tape drives ======
 +
 +The "official" A3070 tape drive is an external QIC 120/150 drive, required for default scripted installation. It's believed to be identical to “Caliper CP150 SCSI QIC” and “Archive Viper 150MB Tape Streamer” (?) (some are rebadged as Connors) but case design is different (the A3070 was designed with an A3000 theme). See the [[https://www.amigaunix.com/lib/exe/fetch.php/downloads:a3070_tape_drive_installation_guide.pdf|Amiga A3070 SCSI tape drive installation manual]] (PDF).
 +
 +
 +Compatible 3rd party SCSI tape drives (must be set to SCSI ID 4)
 +  * Caliper, Sankyo and Wangtek brands of SCSI QIC-150 tape drives (Wangtek 5150 ES verified by user)
 +  * Archive Viper 150 MB (see note below)
 +
 +Note: //Drivers written by Frank Edwards for the Archive Viper tape unit are now included with Amiga Unix. Type Ctrl-D at the first prompt of the installation procedure. Type "viper_kludge". Then type Ctrl-D to resume the installation" // (Source: Amiga Unix Version 2.1 - Addendum). Thanks to mark_k on EAB forums finding [[https://groups.google.com/forum/#!msg/comp.unix.amiga/DY9h44K7vEo/FGppbzz0Z50J|this old discussion]].
 +
 +Not compatible SCSI drives (verified by user): Tandberg TDC4120
 +
 +You won't be able to get the drive to work reliably without the proper termination, so get yourself a DB25 SCSI terminator if necessary. If you need tapes, you can either find somewhere online to buy them new, or you can hit eBay. Used tapes are a dime a dozen on eBay (search for "qic tape").
 +
 +
 +====== Tape commands ======
 +
 +  * re-tension the tape (by fast forwarding and rewinding it): **mt retension** 
 +  * rewind the tape: **mt rewind**
 +  * Zeroing out the tape ("format"), for 2.1 installation: **dd if=/dev/zero of=/dev/rmt/4hn bs=32k** 
 +  * Zeroing out the tape ("format"), for other versions: **dd if=/dev/zero of=/dev/rmt/4n bs=32k**
 +
 +“Using Amiga Unix” mentions tape only shortly on “Backing up your files” (p. 232-235), here are the examples:
 +
 +  * Backing up files to tape: **find /home/joe -depth -print | cpio -ocv -O > /dev/rmt/4**
 +  * List the contents of your backup: **cpio -ictv < /dev/rmt/4**
 +  * Restore files: **cpio -imdcuv -B < /dev/rmt/4**

-This method has been tested using an existing Amiga UNIX install (maybe installed using the HD hack) and a Commodore A3070 tape drive. It is hoped you have these things. In particular the installation is very sensitive to the tape drive used, so you may be wasting your time without an A3070. If you do not have these things, you can attempt to create the tape using a QIC 150 tape drive of any type using DC6150 tapes. You may find the following information from the Amiga-Hardware page about the A3070 helpful: +This method has been tested using an existing Amiga UNIX install (maybe installed using the HD hack) and a Commodore A3070 tape drive.

 This step is also optional, but might save you some time in the long run. Take a look at the cpdist.sh script included with the tape creation script. Modify the device name to be 4hn if you have a 2.1 tape and run it in an empty directory, copying the seglist file into it before you run the script. If you get any errors, you can either try that tape again (retension, zero out, write tape) or try a new tape. No errors? You're ready to install, but it's wise to have a backup tape anyway! This step is also optional, but might save you some time in the long run.
