IMPORTANT TERMINATION INFORMATION
The SCSI Bus Termination jumper enables/disables the on-board active termination. If the SCSI bus is
terminated by an external SCSI terminator, or by another SCSI device with termination enabled, you must remove
this jumper to avoid a termination conflict which could make your computer perform erratically. Conversely, if
the SCSI bus is not otherwise terminated, this jumper must be installed. For AMOS computers, this drive
performs best when used with an external terminator (PRA-00222-xx). We do not recommend using this drive in
an AMOS computer with the SCSI Bus Termination jumper enabled.
The Term Power jumpers let the drive supply power to its own on-board terminators and/or the SCSI bus. In
AMOS applications, we recommend installing the jumper between pin 2 and pin 4. This causes the drive to accept
termination power from the bus if its own terminators are enabled; otherwise, it keeps the drive from interfering
with the bus termination power. Refer to your hardware documentation for more detailed information, or call the
Alpha Micro Technical Assistance Center for help.

SOFTWARE REQUIREMENTS
To use this disk drive, you must use the following minimum file versions (as of 1/98):
For AMOS 1.4C and AMOS 2.3A For AM-1200 Only
FMTS2.LIT 1.0(102)-1 FMTSCZ.LIT 3.1(153)-4
FIXLOG.LIT 1.1 (112) FMTSCZ.OVR 1.0(122)-2
SCZRR.DVR hash= 524-233-343-770
SCZ190.DVR hash= 127-556-203-562
SCZR60.DVR Any released version
Use FMTS2 to format this drive on all systems except the AM-1200. Use FMTSCZ only on the AM-1200,
which doesn't support FMTS2.
BOOT PROM COMPATIBILITY INFORMATION
The following list shows the boot PROM revisions we used when testing this drive for compatibility with the
various Alpha Micro CPU boards. While the drive may function well with earlier revision boot PROMs, it is
supported by Alpha Micro only with these revisions and later.
CPU Board Description PROM Revision
AM-130 AM-1400 E00(B0E-00130-00)
AM-134 AM-1400 E00(B0E-00134-00)

AM-135 AM-1600 E00(PDB-00135-50)
AM-137 Eagle 100 M00 (PDB-00172-90)
AM-140 AM-3000M (with or without AM-540) E00(PDB-00140-50)
AM-172 Roadrunner 030, used in some Eagle M00 (PDB-00172-90)
200/300 computers
AM-174 Roadrunner 040, used in Eagle 200 - 500 and N00 (PDB-00174-90)
Eagle 550 (Super Eagle)
AM-176 Roadrunner 060, AM-6000 A01 (PDB-00176-10)
AM-177 AM-1200 E00(PDB-00178-01)
AM-180 AM-2000VME F00(PDB-00187-00)

AM-190 AM-4000 E00 (DWB-00191-10, Rev. A05)
1. AM-1600 boot PROMs are shipped in an upgrade kit, the part number of which is shown. The revision of
the kit may not match the revision of the PROMs it contains. If the revision shown on the actual boot
PROMs is not at least E00, order the upgrade kit part number shown.
2. AM-4000 boot PROMs are located on a small PCB (printed circuit board) (DWB-00191-10) that plugs
into the AM-190 board. In the table above, the revision of the boot PROMs is E00 and the revision of the
printed circuit board assembly that contains the boot PROMs is A05. If you have an A04 or earlier boot
PROM PCB assembly, simply unplug it and replace it with an A05 or later assembly.
This drive is not supported on the AM-1000. We have not tested this drive with the other systems which aren't
listed (such as the AM-2000M and AM-3000VME), but we have no reason to believe it will not work.
Note that the latest PROM revisions, shown in the table, may have been made for reasons other than disk drive
support. For example, the E00 revision of the AM-190 and the N00 revision for the AM-137 and AM-174 were all
made to support warm booting from various tape devices.
