  There are six jumpers available for configuration. Three of these
  jumpers, E1, E2, and E3, are used to select the drive's SCSI ID,
  while E4 (installed) disables parity. Jumpers E5 and E6 are used to
  enable either the spindle synchronization signal, or LED, respect-
  ively.


 E4  Parity Jumper
 -----------------

 E4     OPEN     Parity check enabled
        CLOSED   Parity check disabled

 There are three removable terminators: RP1, RP2, and RP3. They can be
 removed from the drive, if bus termination is provided elsewhere in
 the system.


 E5  Spindle Synchronization
 ---------------------------
 For use in Disk Arrays, a spindle synchronization feature is
 provided. Spindle synchronization between drives is accomplished by
 connecting a cable to J4 on each of the drives. Up to twelve disk
 drives may be connected, and the method used to implement synchroni-
 zation does not require a designated master drive.

 To construct the cable, a 4-conductor ribbon cable and 14-pin dis-
 placement connector (Molex part number 15-47-3142 or equivalent) are
 required. Install the required number of connectors on the ribbon
 cable with the four conductors in pin position 1-4 (pin positions
 5-14 are unused).

 To install the completed cable, connect the 14-pin displacement
 connector to J4 of each drive. Align pin one of the connector with
 pin one of J4. Install jumper E5 on each drive to enable spindle
 synchronization.

 The drive may be mounted in any attitude!


 Recommended Mounting Configuration
 ----------------------------------
 The Astec disk drives are designed to be used in applications where
 the units may experience shock and vibrations at greater levels than
 larger and heavier disk drives.


 Shock Tolerance Features
 ------------------------
 The features which allow greater shock tolerance are the use of
 rugged media and shock mounts. To take full advantage of the shock
 mounts, it is necessary to provide a minimum of 0.1 inch clearance
 on both the top and sides of the drive. This clearance allows for
 movement of the drive during accleration.


 Mechanically Isolated Mounting Points
 -------------------------------------
 Ten base mounting points are provided to the customer. Each
 mounting point is mechanically isolated from the head/disk assembly.
 The drive is mounted using 6-32 screws; 1/8" max. insertion for the
 sides, and 1/4" max. insertion for the bottom. The system integrator
 should allow ventilation to the drive to ensure reliable drive
 operation over the operating temperature range.

 For additional vibration isolation, an external suspension system
 may be used.


 Cable Requirements
 ------------------
 A 50-conductor flat cable or 25-conductor twisted pair cable is re-
 quired. The maximum cable length is 6.0 meters (19.68 ft).

 The cable characteristic impedance should be 132 ohms   10% with a
 minimum conductor size of 28 AWG.


 Connector Requirements
 ----------------------
 The drive connector is a 50-conductor connector which consists of
 two rows of 25 male pins on 100 mil centers.

 The cable connector is a 50-conductor non-shielded connector which
 consists of two rows of 25 female contacts on 100 mil centers.

 Power Connector
 ---------------
 The drive has a 4-pin DC power connector (J3) mounted on the PCB.
 The recommended mating connector is AMP part number 1-480424-0
 utilizing AMP pins (part number 350078-4 or equivalent).


 Electrical Description
 ----------------------
 The Astec family of drives uses open collector drivers. All assigned
 signals are terminated with 220 ohms to +5 volts and 330 ohms to
 ground. The termination resistors are removable for multi-device
 configurations.


 Cabling
 -------
 Connect the power cable to J3. Connect the SCSI interface cable to
 J2. Bus termination is required on the last device of the SCSI bus.


 Diagnostic Routines
 -------------------
 The microprocessor performs diagnostics upon application of power.
 If an error is detected, the drive will not come ready.


 SCSI Termination
 ----------------
 There are three removable terminators; RP1, RP2 and RP3. They can be
 removed from the drive if bus termination is provided elsewhere in
 the system.


 Magnetic Field
 --------------
 The disk drive will meet its specified performance while operating in
 the presense of an externally produced magnetic field under the
 following conditions.
   +------------------+------------------+
   |Frequency         |   Field Intensity|
   +------------------+------------------+
   |   0 to 700 Khz   |   6 gauss maximum|
   | 700Khz to 1.5Mhz |   1 gauss maximum|
   +------------------+------------------+


 Acoustic Noise
 --------------
 The sound pressure level will not exceed 40 dBA at a distance of 1
 meter from the drive.

 Seek Times
 ----------

       +----------------------------------+--------+
       |Track-to-Track         msec.      |    8   |
       +----------------------------------+--------+
       |               Average msec. typ. |   25   |
       |               Average msec. max. |   45   |
       +----------------------------------+--------+
       |Latency                msec. avg. |   8.4  |
       +----------------------------------+--------+
       The timing is measured through the interface with the drive
       operating at nominal DC input voltages. The timing also
       assumes that the I/O driver overhead and system hardware de-
       pendency have been subtracted from timing measurements.
       The average seek time is determined by averaging the seek time
       for a minimum of 1000 seeks of random length over the surface
       of the disk.


 Output Characteristics
 ----------------------
 Each signal driven by the drive has the following output character-
 istics when measured at the drive connector:

  +--------------------------------+----------------------------+
  |Signal Assertion                | 0.0 VDC to 0.4 VDC         |
  +--------------------------------+----------------------------+
  |Minimum Driver Output Capability| 48ma (sinking) at 0.5 VDC  |
  +--------------------------------+----------------------------+
  |Signal Negation                 | 2.5 VDC to 5.25 VDC        |

 Functional Description
 ----------------------
 The Astec series of disk drives contains all necessary mechanical
 and electronic parts to interpret control signals, position the
 recording heads over the desired track, read and write data, and
 provide a contaminant free environment for the heads and disks.


 Read/Write and Control Electronics
 ----------------------------------
 One integrated circuit is mounted within the sealed enclosure in
 close proximity to the read/write heads. Its function is to provide
 head selection, read pre-amplification, and write drive circuitry.

 The single microporcessor-controlled circuit card provides the re-
 maining electronic functions which include:

        - Read/Write Circuitry
        - Rotary Actuator Control
        - Interface Control
        - Spin Speed Control
        - Dynamic Braking

 At Power Down, the heads are automatically retracted to the inner
 diameter of the disk, and are parked and latched on a landing zone
 that is inside the data tracks.


 Drive Mechanism
 ---------------
 A brushless DC direct drive motor rotates the spindle at 3575 rpm.
 The motor/spindle assembly is dynamically balanced to provide minimal
 mechanical runout to the disks. A dynamic brake is used to provide a
 fast stop to the spindle motor and return the heads to the landing
 zone when power is removed.


 Air Filtration System
 ---------------------
 Within the sealed enclosure, a 0.3 micron provides a clean environ-
 ment to the heads and disks.


 Head Positioning Mechanism
 --------------------------
 The Read/Write heads are supported by a mechanism coupled to a voice
 coil actuator.


 Read/Write Heads and Disks
 --------------------------
 Data is recorded on 95mm diameter disk through 3370 type heads.


 Error Correction
 ----------------
 The Astec series of disk drives performs internal error correction.
 The six-byte error correction polynominal is capable of correcting
 one error bursts with a maximum of 8 bits per 512-byte block.


 Reliability and Maintenance
 ---------------------------
 MTBF                     50,000 hours (POH); population is minimum
                          of 100 units.
 MTTR                     10 minutes typical
 Preventive Maintenance   None
