A.1.1Tandberg 1/4" Streaming Tape Drives
In order to warm boot from a Tandberg tape drive, it must be set to a higher numerical
SCSI ID (1 through 6) than any other tape device connected to the SCSI bus.
1.In order to be Roadrunner compatible, the AM-625 Tandberg 150MB tape
drive must have firmware at revision -06:00 or later. You can use the
SCSI.LIT program (included in AMOS 2.2C and 1.4C operating system
releases) to determine the firmware revision of your tape drive. Simply
type in the command SCSI at the AMOS prompt and the program will
display a string of numbers which includes the firmware revision. The
AM-625 is a SCSI-1 device; it cannot be upgraded to SCSI-2. AM-625
backups are not able to span tapes.
2.AM-626 525MB Tandberg SCSI tape drives can be upgraded to SCSI-2 in
two ways. Older models of the TDC 3800 with firmware revisions earlier
than -07:01 must be upgraded by physically upgrading the firmware
PROM located inside the drive (p/n PDB-00626-90). Newer models of the
TDC 3800 with firmware revisions -07:01 or later, use flash ROM similar to
the larger Tandberg 1GB and 2GB streamer drives. The flash ROM type
drives can be upgraded without removing the drive from the computer. To
upgrade the newer model of the 3800 see step 3.
If the firmware is not upgraded, the drive can still be used with Roadrunner
hardware as a SCSI-1 device, but only if it has firmware at revision -04:08
or later. You can use the SCSI.LIT program as explained in step 1 to
determine the firmware revision of your tape drive.
To replace the firmware PROM, simply remove the two TORX screws
holding the drive’s top cover in place; lift off the top cover; gently pry out
the old PROM; and install the new PROM as shown:

in the chip (indicating
pin-1) points toward
the rear of the drive.
