Installation Instructions: AM-642 STOP Converter
Rev. A01
Termination Power
All AMOS computers using the SCSI-2 or Wide SCSI-2 bus should be configured to supply termination
power via the host controller. When SCSI bus termination power is supplied by the host controller, no
SCSI peripheral, including the AM-642, should supply termination power to the bus.
SCSI subsystems attached to the main system should not have any additional devices supplying
termination power to the SCSI bus. Termination power should be supplied by the SCSI controller only!
The SCSI host controller on AM-190 and AM-540 boards is permanently configured to supply
termination power to the SCSI bus. On Roadrunner boards, the termination power feature can be
enabled or disabled by setting a jumper. As of 07/26/94, Alpha Micro began configuring all
Roadrunner boards with termination power enabled. See the Roadrunner installation instructions
for information on how to configure the termination power jumper.
Electrical Power
For reliable operation, the AM-642 should be plugged into the same power source as the computer it is
attached to. Do not plug it into a separate power circuit.

•
You can have multiple SCSI tape drives attached to your computer system.
•
The AM-642 should be referred to as device MTX0:.
•
AMOS does not support warm booting from a tape drive attached to the AM-642.
Copying the Device Driver Program
You need to make a copy of the driver you require under a three-character name so AMOS can associate
it with the device name you are going to put in your system initialization file. To do so, type:
LOG DVR:
RETURN
COPY MTX.DVR=645DVR.DVR
RETURN
