Changing the SCSI ID num ber
Because it is a standard for the Amiga 3000 and 3000UX
operating s stems, the 3070 Tape Drive comes configured as
SCSI device number 4. It is highl recommended that UNIX®
users, in particular, leave the SCSI ID set to 4 because man
UNIX operations assume it is set as such. If necessar , ou can
change the SCSI ID Number b using the dip switches located
inside of the tape drive case.
To change the SCSI ID:
1. IMPORTANT: Make sure the power to the tape drive
and the Am iga 3000 is OFF. Disconnect the power
cables.
2. Disconnect the SCSI cable from the back of the Amiga
3000.
3■ Facing the rear of the tape rive, remove the screw that
hol s the bottom plate to the case (Figure 8).

4. Turn the tape rive over an remove the plate by sli ing
an lifting it off of the case.
You will see the tape drive within the case.

Introduction
The Commodore 3070 Tape Drive is designed for use with
the Commodore Amiga 3000 and the Amiga 3000UX.
With the 3070 Tape Drive, ou can back up the data on our
hard disk to magnetic tape. Because of the greater storage
size of magnetic tape, it is much quicker and simpler than
backing up to flopp disks.
Performing regular backups of our s stem reduces the risk
of data loss from human and hardware errors, and provides a
convenient wa to exchange data between s stems and load
new software or s stem updates.
Before proceeding, examine the contents of our package. In
addition to this manual, ou should find:
• One Commodore 3070 Tape Drive
• One SCSI Terminator Block
• One Power Cable

Understanding SCSI devices
Throughout this manual ou will see references to SCSI
devices. SCSI (Small Computer S stem Interface) is a
industr -wide standard interface (or connection), designed
to be compatible with man t pes of computers and
peripherals. The Commodore 3070 Tape Drive is a SCSI
device, meaning it conforms to the SCSI standard.
SCSI devices are found inside and outside of our computer.
Some SCSI devices are internal (connected inside of the
computer), such as an internal SCSI hard disk. The 3070 Tape
Drive is an external SCSI device; it is situated outsi e of the
computer and linked to the computer via a SCSI cable. The
Commodore 3070 Tape Drive operates through the SCSI
port, located in the rear of the Amiga 3000.
External SCSI devices for the Amiga 3000 are designed to
dais chain to our s stem. This means the first SCSI device
is connected to the SCSI port on our Amiga 3000; the
second SCSI device is connected to the SCSI port on the first
SCSI device, etc. This forms a chain back to our s stem and
can continue until ou reach a maximum of seven SCSI
devices (both internal an external).
The SCSI device chain must be terminated at both ends with
special terminators (such as the SCSI Terminator Block
supplied with the 3070 Tape Drive). The internal end of the
SCSI connector on the Amiga 3000 is alread terminated. You
must assume responsibilit for the other end b terminating
the open SCSI port on the last SCSI device hooked to our
s stem.
3

For example, if our onl external SCSI device is the 3070
Tape Drive, connect the included SCSI Terminator Block to
the open SCSI port on the back of the tape drive. With more
than one SCSI device, make sure the last device is terminated.
If som e o f our SCSI devices are not recognized b our
s stem, or if our com puter w ill not boot, it could be
caused b im proper termination. Make sure ou have
terminated the last SCSI device in the chain. Do not terminate
an devices in the middle of the chain. (Note that SCSI hard
disks usuall have removable termination built in. Consult
our dealer for more information.)
Installing the tape drive as the
only external SCSI device
1) IMPORTANT: Make sure that the power to the
s stem is disconnected before ou begin to install
the 3070 Tape Drive. Failure to observe this
precaution could produce injur to the user and
damage to the equipment.
2) Connect the tape rive’s SCSI Cable to the SCSI port in the
rear o f the Amiga 3000 (Figure 1).
IMPORTANT: The Amiga 3000 has other 25 pin
connectors in the area of the SCSI port. MAKE SURE to
connect the cable to the port marked SCSI.
Connecting the cable to the wrong port could damage
our equipment.

3) Remove the SCSI Terminator Block from the box an
connect it to the open SCSI port on the back of the tape
rive (Figure 2).
4) Connect the power cable to the power supply connector
on the rear of the tape rive (Figure 3)■

5) Plug in the tape rive. Do not pow er it up et—the
computer will not boot unless the tape rive is powere
on at the same time as the system.
6) Reconnect the power to your system. Power up the tape
rive (by flipping the power switch on the left rear) at
the same time you power up your system
A fan turning on within the tape drive will indicate that the
tape drive is on. Unless there is a tape cartridge in the
tape drive, the light on the tape drive will not go on.

Installing the tape drive to a
series of external SCSI devices
To install the tape drive to a series of SCSI devices:
1) IMPORTANT: Make sure that the pow er to the
s stem and to all SCSI devices is disconnected
before ou begin to install the 3070 Tape Drive.
Failure to observe this precaution could produce
injur to the user and damage to the equipm ent.
2) Disconnect the first SCSI evice of the chain from your
system an connect it to the back of the tape rive
(Figure 4).

3) Connect the tape rive’s SCSI Cable to the SCSI port in the
rear of the Amiga 3000 (Figure 5).
IMPORTANT: The Amiga 3000 has other 25-pin
connectors in the area of the SCSI port. MAKE SURE to
connect the cable to the port marked SCSI.
Connecting the cable to the wrong port could damage
our equipment.
4) Make sure the last SCSI evice in the chain has a SCSI
Terminator Block covering its open SCSI port. If it oes
not,; locate the SCSI Terminator Block that came with
that evice (orpurchase one) to connect to its open SCSI
port.
5) Connect the power cable to the power supply connector
on the rear of the tape rive an plug it in (Figure 6).

6) Reconnect the power to all of the evices you unplugge ,
but o not power them up.
7) Power up the tape rive; the other SCSI evices in the
chain, an the system.
In order for the s stem to boot up, all SCSI devices in
the chain must be powered up at the same time as the
s stem. You ma decide to connect the devices to a power
strip, so ou can power up all devices b simpl turning on
the power strip.

A fan turning on within the tape drive will indicate that the
tape drive is on. The light on the tape drive w ill not go on
unless there is a tape cartridge within the tape drive.
Loading and unloading the tape
cartridge
Note: DO NOT OPEN THE DOOR on the tape drive
unless the light on the front is glowing green (when
cartridge is installed but not operating) or when the
light is off (no cartridge is installed). Failure to observe
this precaution ma cause data loss.
Loading the tape cartridge into the drive is a simple
operation:
1) Open the front oor of the tape rive by pressing the
eject button on the upper left han comer.
The door will spring halfwa open. Gentl press down on the
door until it stops.
2) Insert the cartri ge into the oor with the metal si e
own an the notches facing to the left.
3) Once the cartri ge is hel in place by the rive; push the
oor shut.
If the tape is inserted incorrectl , the door w ill not
shut. Do not force it.
The cartridge is properl installed if the door shuts full and a
“click” is heard when the eject button goes back into place.
10

To unload the cartridge:
1) When the tape rive light is GREEN ( the tape is not
moving), press the eject button, then gently press own
on the half-opene oor until the cartri ge sli es out of
the rive.
2) Grab the en of the cartri ge an sli e it the rest of the
way out of the rive.
3) Close the oor an return the cartri ge to its protective
box.
Compatible tape cartridges
Use onl cartridges that were designed for operation
with the Com m odore 3070 Tape Drive. 3M® DC600XTD,
3M DC6150, and the Carlisle DC-6150 are recommended for
use with this s stem.
Care and handling
Tape drive head cleaning should be part of our regular
maintenance program. Make sure that it includes these
points:
• Clean the recording head after ever 500 passes.
• Use onl approved cleaning solutions and materials.
11

To keep the data stored on tape cartridges safe, follow
these guidelines:
• Do not clean or touch the tape or tape rollers with
our fingers or an foreign objects.
• Alwa s remove the cartridges when the drive is not in
use.
• Keep the cartridge in its protective box when it is not
in the drive.
• Keep the cartridges awa from strong magnetic fields.
• It is important to rem em ber that our tape
cartridges and drives are sensitive to
temperature variations. Do not tr to operate our
drive in temperatures below 40 F (5 C) or above 110
F (45 C). Do not store our tapes or tape drive where
the will be exposed to temperatures below — 40 F
( — 40 C) or above 140 F (60 C).
Write protecting a tape cartridge
To avoid inadvertentl over-writing a cartridge, ou can
write protect a cartridge it just as ou would a flopp disk.
B write protecting a cartridge, no data can be written over
the data alread on the tape.
Notice that the tape cartridge contains a barrel plug in the
upper left-hand corner that sa s “SAFE”. To write protect a
cartridge, using a coin or screwdriver, turn the arrow on the
plug so it points to SAFE (Figure 7).
