  +------+------+------+-------------------------------------+

 Note: In the 40/80AT mode, PDIAG- is not used; otherwise, it is
 always used.


 DS  Drive Select Jumper
 -----------------------
 x   CLOSED  Single drive or MASTER (Drive 0)
     OPEN    SLAVE (Drive 1)

 You can daisy-chain two drives on the AT-bus interface by using
 their Drive Select (DS) jumpers to configure one drive as the Master
 and the other as the Slave.

 Note: The order in which drives are connected in a daisy chain has no
       significance.


 SP  Slave Present Jumper
 -------------------------
 In combination with the current DS jumper settings, the Slave Present
 (SP) jumper implements one of two possible configuratons:

 When the drive is configured as a Master - that is, with the DS
 jumper installed - the SP jumper should be installed on the Master
 drive only if the Slave drive does not use the Drive Active/Slave
 (DASP-) signal to indicate its presence.

 When the drive is cnfigured as a Slave - that is, without the DS
 jumper installed - the SP jumper enables the self-seek test. When
 power is applied to the drive with the self-seek test enabled, the
 drive executes seeks in a butterfly pattern.

 During the self-seek test, the LED remains on whle the test proceeds
 without error. If the test encounters a seek error, the test
 terminates and the LED flashes continuously until the SP jumper is
 removed.


 DM  Drive Mode Jumper
 ---------------------
 When the Drive Mode jumper is installed, the drive is in the ProDrive
 40/80AT-compatible mode and can communicate with a ProDrive 40/80AT
 hard disk drive. In this mode, the drive does not use the PDIAG-
 signal to control Master/Slave communications. The configuration of
 the DS and SP jumpers determines whether the drive is the Master
 or the Slave.

 --------------------+ pin 4    + 5 VDC

 Note: Labels indicate the pin numbers on the connector. Pins 2 and 3
 are connected on the drive.

 ---------------------------------------------------------------------

 Adapter Board Jumper Options
 ============================
 Four jumper pins on the adapter board - labeled J2 through J5 - have
 the function described below.

 J2  Enables the drive's interrupt logic to control IRQ14
     (Interrupt Request 14). This option provides compatibility
     with systems in which the BIOS does not read the STATUS Register
     when the drive issues an interrupt. In such cases, the drive
     might fail to transmit the interrupt to the system.

     - A jumper from the center pin J2 to E3 enables transmission of
       an interrupt every time the drives goes busy.

     - A jumper from the center pin J2 to E4 gates the interrupt from
       the drive and transmits it directly to the AT bus. This is the
       default setting.

 J3  These pins should always remain open, with no jumper installed.

 J4  This jumper should generally remain open. A jumper should be
     installed here only when installing the adapter board
     in a system that uses the Chips & Technologies chip set. This
     chip set runs the I/O bus faster than the standard 12 Mhz, one
     wait state.

 J5  Enables secondary interface selection on a second adapter board
     installed in a system. When a jumper is installed here,
     drives connected to the adapter board respond to commands
     transmitted via the secondary address, 170H-177H. Standard BIOS
     versions do not support secondary addresses. Therefore, you must
     write a custom driver to implement a secondary interface.

 Note: A second adapter board is supported only when both adapter
       boards are Quantum boards.

 Notes on Installation
 =====================

 Mounting
 --------
 The mounting holes on the ProDrive LPS 80AT hard disk drive
 allow the drive to be mounted in any orientation. For mounting, #6-32
 UNC screws are recommended.


 Caution: The PCB is very close to the mounting holes. Do not
 exceed the specified length for the mounting screws. The specified
 screw length allows full use of the mounting-hole threads, while
 avoiding damaging or placing unwanted stress on the PCB. To avoid
 stripping the mounting-hole threads, the maximum torque applied to
 the mounting screws must not exceed 8 inch-pounds.


 Ventilation
 -----------
 The ProDrive LPS 80AT hard disk drives operates without a cooling
 fan, provided the ambient air temperature does not exceed 122*F
 (50*C). Any user-designed cabinet must provide adequate air circula-
 tion, to prevent the maximum temperature being exceeded.


 J1 AT-Bus Interface Connector
 -----------------------------
 On the ProDrive LPS 80AT hard disk drive, the AT-bus interface
 cable connector (J1) is a 40-pin Universal Header.

 To prevent the possibility of incorrect installation, you should be
 keyed by removing pin 20. This will ensure that the connector cannot
 be installed upside down. All signal are relative to Pin 20.

 For the mating J1 connector, recommended cable connectors include AMP
 receptacle P/N 1-499506-0, with strain relief; P/N 1-746193-0, with-
 out strain relief; or an equivalent. To key the cable connectors, you
 must plug the hole that corresponds to pin 20.

 Other recommended part numbers for the mating connector include:

   40-Pin Connector               3M 3417-7000 or equivalent

   Strain Relief                  3M 3448-2040 or equivalent

   Flat Cable (Stranded 28 AWG)   3M 3365-40 or equivalent

   Flat Cable (Stranded 28 AWG)   3M 3517-40 (shielded) or equivalent


  Adapter Board Installation
  --------------------------
  The adapter board is a half-size board. You can install it in any
  available 16-bit slot in an IBM PC-AT or compatible personal
  computer. Before installing the adapter board, make sure that no
  other hard drive controller resides at the primary hard drive
  address, 1F0H-1F7H.

  If a combination floppy and hard disk drive controller is present,
  its hard disk drive controller functions must be disabled.
  To disable the hard disk drive controller functions, follow these
  instructions:

  On a Western Digital WD1002-WA2 or WD1003-WA2 floppy/hard disk drive
  controller card:

   - Do not install jumpers on pins E5 and E6.
     Install jumpers on pins E4 and E5 to ensure that the controller
     card resides at the secondary address, 170H-177H, rather than at
     the primary address, 1F0H-1F7H.

   - Move the card from a 16-bit I/O slot to an 8-bit slot to
     disconnect the IRQ14 output driver.

  On a Data Technology Corporation (DTC) floppy/hard disk drive
  controller card:

   - Install a jumper on pins W3.

   -  Move the card from a 16-bit I/O slot to an 8-bit slot to
      disconnet the IRQ14 output driver,

  Once you have disabled hard disk drive controller functions on the
  card, install the adapter board in a 16-pin slot.


  Connecting the Adapter Board and the Drive
  ------------------------------------------
  Use the ribbon cable supplied with the adapter board to connect the
  drive to the board. To ensure that the cable is plugged into the
  adapter board and the drive correctly, there is a red wire at one
  edge of the cable. To connect the drive to the board:

  1. Note the number 1 printed on the board next to the header. When
     inserting the cable connector into the header on the adapter
     board, make sure the red wire on the cable is at the side of the
     header labeled 1.

  2. When inserting the other end of the cable connector into the
     header on the drive, make sure the red wire on the cable is at
     the inside edge of the header, next to the J3 power connector.

  To complete the installation of the drive, secure it to the system
  chassis by using the mounting screws.


 J3 DC Power Connector
 ---------------------
 The drive's DC power connector is a 4-pin Ranoda Electronics
 Connector (06300010-04-1) or equivalent, mounted on the back edge of
 the Printed Circuit Board (PCB).

 Recommended connectors and their numbers:

  4-pin connector       AMP P/N 1-480424-0 or equivalent

  Loose-piece contacts  AMP P/N 61173-4 or equivalent

  Strip contacts        AMP P/N 350078-4 or equivalent


 Air Filtration
 --------------
 Low Profile Series hard drives are Winchester-type drives. The heads
 fly very close to the media surface, at a nominal flying height of
 4 microinches. Therefore, it is essential that the air
 circulating within the drive be kept free of particles. Quantum
 assembles the drive in a Class-100, purified-air environment, sealing
 the drive mechanism under a metal cover. When the drive is in use,
 the rotation of the disks forces the air inside the drive through an
 internal filter.


 Electrical Characteristics
 --------------------------
 All signals are TTL-compatible - with logic one greater than 2.0
 volts and less than 5.25 volts; and logic zero, greater than 0.0
 volts and less than 0.7 volts. Neither the adapter board nor the
 drives require terminating resistors.


 AT-Bus Interface Characteristics
 --------------------------------
 The AT-Bus interface supports one or two hard drives per adapter
 board and a maximum of two adapter boards - or a maximum of four
 drives. When more than one drive is present, a master/slave
 relationship exists between the two drives. The host always maintains
 control of the bus - no arbitration occurs.

QUANTUM  PRODRIVE LPS 80 AT  PRODUCT MANUAL 6/11/91

 General Description
 -------------------
 Quantum's ProDrive Low Profile Series (LPS) 80AT hard disk drives are
 a part of a family of high-performance, 1-inch-high hard disk drives
 manufactured to meet the highest product quality standards. ProDrive
 LPS hard disk drives use nonremovable, 3 -inch hard disks, and are
 available with a Small Computer System Interface (SCSI) or Advanced
 Technology (AT) interface.

 The ProDrive LPS 80AT hard disk drives feature an embedded AT
 drive controller and use AT commands to optimize systems performance.
 Because the drive manages media defects and error recovery
 internally, these operations are fully transparent to the user.

 -----------------------+-----------+-----------+------------+


 Preventive Maintenance
 ----------------------
 The ProDrive LPS 80AT hard disk drive requires no preventive
 maintenance.


 Defect Detection
 ----------------
 At the sector level, any discrepancy between recorded data and re-
 covered data constitutes a data error. In high-density digital re-
 cording systems, it is necessary to use an error-detection and
 correction scheme to increase the reliability of the system.

 Data errors are either soft- not readily repeatable on retries - or
 hard - repeatable with high probability. The signal-to-noise ratio of
 the system affects the occurrence of soft errors, which present
 marginal conditions of the media, heads, or read/write circuitry.
 Hard errors occur due to defects, pits, scratches, or thin spot in
 the media. The drive can skip, or not use, defective sectors on the
 media for data storage.


 Defect Management
 -----------------
 Factory Found Defects
 At the factory, Quantum scans the disks for defective sectors and de-
 allocates sectors containing defects prior to shipment. The drive re-
 cords a primary defect list that contains the locations of all
 factory-found defective sectors in a reserved cylinder on the disk.
 In-line sparing skips each factory-found defect and shifts
 subsequent sectors on the track to sequential sectors. One sector at
 the end of each cylinder is a spare, or replacement sector. The drive
 allocates spare sectors as required to maintain the proper number of
 blocks per cylinder.
