NOTE 1: The drive may be installed in one of five
orientations, either PCB down or on any
NOTE 2: For a Compaq drive, the spin up delay for
each drive is 10 sec x SCSI ID setting. Therefore, if any
of these drives are configured for SCSI ID 2 or higher,
you will need to insert a SLEEP command just prior to
the SCZDSP command to delay execution of the
SCZDSP command long enough for these drives to
spin up.

IMPORTANT TERMINATION INFORMATION
Most disk drives do not contain SCSI bus terminators, and the SCSI bus must be terminated at its physical end by
an external terminator. Only the Seagate ST39173W drive contains an on-board SCSI bus terminator. For this
drive, the SCSI Bus Te rmination jumper enables/disables this 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 active terminator (PRA-00222-xx). We do not recommend using this
drive i n a n AMOS c o m p uter with the SCSI Bus T ermination jumper enabled. See the jumper setting details on
pages 1 and 2 for additional details.
The Term Power jumper(s) lets the drive supply power to the SCSI bus and its own on-board terminators if it
contains any.
For the Seagate ST39173W drive only, we recommend installing the jumper between J2 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.
For other drives, we recommend configuring the drives so that SCSI termination power is supplied
externally and is not affected by the disk drive.
Refer to your hardware documentation for more detailed information, or call the Alpha Micro Technical
Assistance Ce nt e r for he l p.
SOFTWARE REQUIREMENTS
In order to create a single logical device for the 8.6 and 17.4 GB disk drives (AMOS 2.3A), the fo l l o wi n g
patch is required:
SP2040: AMOS.MON 2.3A(485) or later hash = 070-324-447-627 (use MONHSH)
In order to create a single logical device greater than 16 GB, the following software is required:
BITMAP.LIT 2.1(118)-2 or later hash = 052-154-570-143
New versions of the SCSI dispatcher are required when using these drives. These new versions are as follows:
SCZRR.SYS 1.0(117)-2 or later hash = 606-251-312-174
SCZ190.SYS 1.0(117)-2 or later hash = 642-025-245-424
In addition, when using the Fujitsu or Compaq drives with AMOS 1.4E, the f o l l o wi n g patches are required:
SP2030: DSKANA.LIT 1.0(117) or later hash = 701-635-215-412
SP2031:RNDRED.LIT 1.0(102) or later hash = 310-220-732-147
When using large capacity disk drives with AMOS 1.4E, you are limited in disk drive capacity to 85
logical disks (only 2.8 GB). This is due to input line limitations in the text editor used to create the
BITMAP and DEVTBL statements in the SYSTEM.INI file, which require all information on one text line.
We tested these drives using the following versions of related software. While the drives may work with earlier
software versions, Alpha Micro supports them with these versions and later.
The Fujitsu MAJ3091LP and MP, MAH3091MP, MAJ3182LP, MAN3184MP and the Se a gate ST39205LW and
ST318203LW are not support e d on AMOS 1. 4.

BOOT PROM COMPATIBILITY INFORMATION
The following tables show the boot PROM revisions we used when testing these drives for compatibility with the
various Alpha Micro CPU boards. While the drives may function well with earlier revision boot PROMs, they are
supported by Alpha Micro only with these revisions and later.

These drives are not support e d on t he SASI bus on ol de r AMOS CPU boa rds. T he y a re supporte d onl y on t he
SCSI-2 and Wide SCSI-2 bus (also called “dispatched SCSI”). To use these drives on the narrow SCSI-2 bus, you
must use an adapter between the drive and the SCSI cable.
Note that the latest PROM revisions, shown in the table above, may have been made for reasons other than disk
drive support.
