Installation Instructions: AM-650 1/4" Streaming Tape Drive Page 1 INTRODUCTION This document describes the installation of an AM-650 (Tandberg MLR-1) SCSI 1/4" magnetic streaming tape drive into an existing Alpha Micro computer system. If you are installing an AM-650 tape drive into an external subsystem, use the installation instructions shipped with the subsystem in conjunction with the drive-specific instructions in this document.
Page 2 Installation Instructions: AM-650 1/4" Streaming Tape Drive The AM-650 has the same environmental specifications as your computer. The AM-650 is supported only on the SCSI-2 bus (either narrow or wide). It is not supported on the SASI bus found on older AMOS computers. TOOLS REQUIRED For most installations, the only tool you will need to install the AM-650 is a #2 Phillips-head screwdriver.

Termination power is provided by the SCSI controller. TERMPWR ENTERM: Install only if this is the last device on the SCSI bus and there is no external terminator. ENTERM SEL0 SEL1 SEL2 SEL3 PARITY SEL 0 - 3: Select SCSI ID. See below. PARITY: Should not be installed on AMOS computers.
Page 4 Installation Instructions: AM-650 1/4" Streaming Tape Drive Setting the SCSI ID Each SCSI device attached to the SCSI bus must be set to a unique address. Two SCSI devices cannot share the same address. The AM-650 is a Wide SCSI-2 device, and can therefore be set to any SCSI ID from 0 through 15 (except 7, which is reserved for the SCSI controller). On the narrow SCSI bus supported on AMOS computers prior to the AM-6000 (and optionally on the AM-6000), you can use only IDs 0 through 6.

The top picture shows an external narrow SCSI connector and bail locks for holding the terminator in place.
Page 6 Installation Instructions: AM-650 1/4" Streaming Tape Drive Internal SCSI Bus Termination If you are not using external SCSI termination, you may terminate the SCSI bus by enabling the termination resistors on the last SCSI device—the one farthest away from the SCSI controller. For best termination and most reliable SCSI performance, this device should be at the actual physical end of the SCSI cable.
Installation Instructions: AM-650 1/4" Streaming Tape Drive Page 7 INSTALLING THE AM-650 The following sections explain how to install the SCSI streamer and cable it to your computer, based on the type of computer you have. Find the heading for your computer chassis and follow the instructions. Follow the instructions in your computer Owner's Manual for turning off the power to each component. Be sure to observe the cautions concerning electrostatic discharges and grounding.

Because the tape drive internally ties logic ground to its frame, you need to isolate the tape drive from the computer chassis.

Page 12 Installation Instructions: AM-650 1/4" Streaming Tape Drive AM-990 Chassis Installation The AM-650 is installed in the AM-990's main drive bay using plastic mounting rails. You need two rails to mount the drive (or any peripheral device). The rails (DWF-20652-00) are included with the computer chassis and are universal; they can be mounted on either the right or left side of the drive.
Installation Instructions: AM-650 1/4" Streaming Tape Drive Page 13 DWF-20652-00 MOUNTING RAIL Figure 8 - Attaching Mounting Rails to Peripheral Once the rails are installed, slide the tape drive into its mounting position in the chassis. Attach the power cable from the power supply to the four-pin connector on the drive. Attach the Wide SCSI cable to the 68-pin connector on the drive. The drive’s connector is keyed so the cable can only be attached correctly.
Page 14 Installation Instructions: AM-650 1/4" Streaming Tape Drive Copying the Device Driver Program You need to copy the 625DVR.DVR streaming tape driver file to the file name STR.DVR, so AMOS can associate it with the device name (STR0:) you are going to put in your system initialization file. To do so, type: LOG DVR: RETURN COPY STR.DVR=625DVR.DVR RETURN As long as you are using AMOS 2.3A or later, the driver file 625DVR.DVR is compatible with the AM-650.
Installation Instructions: AM-650 1/4" Streaming Tape Drive Page 15 If you have two streaming tape drives, enter both device names after the slash, separated by a comma, like this: DEVTBL /STR0,STR1 The device driver program needs to be in system memory, so add the following line somewhere before the final SYSTEM command: SYSTEM STR.DVR[1,6] Since the MTUxxx programs spawn a separate job to communicate with the tape drive, you may need to increase the number of jobs allocated by the system at boot time.
Page 16 Installation Instructions: AM-650 1/4" Streaming Tape Drive files stored on the tape cartridge. If you aren’t familiar with the MTUxxx commands, refer to your System Commands Reference Manual for instructions. USING THE AM-650 Use only the MTUSAV, MTURES, and MTUDIR commands to write to and read from the AM650.
Installation Instructions: AM-650 1/4" Streaming Tape Drive Page 17 This means that, if you use TMODE to set, for example, QIC-150 format, then switch tapes, the AM-650 will try to write to the new tape in QIC-150 format. If the tape does not support this format, the write operation will fail! 4. To write to a different kind of tape, you need to use TMODE again to set the proper recording format for the new tape. You need to continue to use TMODE each time you switch tapes until you reset the computer.

Page 20 Installation Instructions: AM-650 1/4" Streaming Tape Drive Care of Streaming Tape Cartridges A cartridge tape can store all the data on your computer, so it is worth taking care of properly. In addition to the tips for diskettes, above, remember the following: • Store cartridges with the write-protect switch in the SAFE position. • Keep magnets away from your tapes. Even weak magnets such as those in paper clip holders can erase data on a cartridge tape.
