What kind of 4.3BSD machine? A VAX? Sorry, this would be the wrong
forum. I can tell you how to install it on a FreeBSD machine, though.

1. Check that the machine has a SCSI host adapter and a cable with a
spare connector. You should be able to confirm this without
shutting the machine down. If you don't have a host adaptor, or
the cable doesn't have a spare connector, get another cable with
more connectors (if you have less than 7 devices on the cable), or
another host adapter and a cable if there are already the maximum
7 devices on the cable.
2. Check the device IDs. If you don't know them, look at the output
from dmesg. It should look something like:
ahc0: <Adaptec 2940 SCSI host adapter> rev 0x03 int a irq 12 on pci0.18.0
ahc0: aic7870 Single Channel, SCSI Id=7, 16 SCBs
ahc0: waiting for scsi devices to settle
scbus0 at ahc0 bus 0
This is the SCSI host adapter, on ID 7.
scbus0 target 0 lun 0: <MICROP 2112-15MQ1094802 HQ48> type 0 fixed SCSI 2
sd0 at scbus0 target 0 lun 0
First disk, ID (target) 0
sd0: Direct-Access 1001MB (2051615 512 byte sectors)
sd0: with 1760 cyls, 15 heads, and an average 77 sectors/track
scbus0 target 3 lun 0: <IBM DORS-32160 WA0A> type 0 fixed SCSI 2
Second disk, ID 3
sd1 at scbus0 target 3 lun 0
sd1: Direct-Access 2063MB (4226725 512 byte sectors)
sd1: with 6703 cyls, 5 heads, and an average 126 sectors/track
scbus0 target 4 lun 0: <ARCHIVE Python 28849-XXX 4.CM> type 1 removable SCSI 2
First tape, ID 4
st0 at scbus0 target 4 lun 0
st0: Sequential-Access density code 0x0, variable blocks, write-enabled
scbus0 target 4 lun 1: <ARCHIVE Python 28849-XXX 4.CM> type 8 removable SCSI 2
This system has four devices on the bus: Disks on IDs 0 and 3, a
tape on ID 4, and the host adapter itself on ID 7. You can use
any other ID for the (second) tape, but I'd recommend keeping 0 to
3 for disks, 4 and 5 for tapes, and 6 for CD-ROMs as long as these
IDs are free. In this case, therefore, I'd recommend ID 5.
3. Set the ID jumpers on the device. Tandberg tapes should be
well-marked, you should find three jumpers to set, for ID 1, 2,
and 4. Set the appropriate combination to add up to your ID (in
this case, 1 and 4).
4. If this is the only device on the SCSI cable, make sure that the
terminators are enabled. I don't know the 3820, but I do know the
3800, and it has terminator resistors. Make sure they're inserted
if this is the only device. If you're installing into a chain
where there are already devices installed, such as in this
example, make sure they're removed. Only the last device on the
cable should have terminators.
5. Shut the machine down.
6. Find a slot to insert the tape drive, and insert it.
7. Connect the SCSI cable and power cable to the tape drive.
8. Reboot. During reboot, or later with dmesg, you should see:
scbus0 target 5 lun 0: <TANDBERG TDC 3820 -03:> type 1 removable SCSI 1
st1 at scbus0 target 5 lun 0
st1: Sequential-Access density code 0x0, drive empty
That's all there is to it!
