 Jumper Setting
 ==============

 Switch S1
 The first three switch positions select the drive's address number.
 They are binary coded, and no two drives in the chain may have the
 same number selected. The other three positions set sector size, and
 spindle control option.


 Drive Select S1
 ---------------
   +----------+-----------------------+
   | Drive    |        Jumpers        |
   | Selected |  3    |   2   |   1   |

   |   NONE   | OPEN  | OPEN  | OPEN  | OPEN   = OFF
   |    1     | OPEN  | OPEN  | CLOSED| CLOSED = ON

   |    7     | CLOSED| CLOSED| CLOSED|
   +----------+-------+-------+-------+
 Up to seven drives may be active and selected. The three positions,
 S1-1, S1-2, and S1-3, correspond to three drive select lines on the
 control bus.


 Setting the sector size
 -----------------------
 There are two methods of selecting the size of a sector: via the
 SET SECTOR command and via switch S1 positions 4 and 5. You might
 prefer the command since it overides the switch settings.

  1. Setting Sector Size by Command.
     Send SET SECTOR command with the desired sector size - in bytes
     per sector - in bit positions 11-0. The resulting sector will be
     an even number.

  2. Setting Sector Size by Switch.
    +------------+--------------------+-------------+------------+
    |            | Physical           |Logical      |  Track     |
    |S1-4   S1-5 | Size in Bytes      |Size in Bytes|  Capacity  |
    +------------+--------------------+-------------+------------+
    | OFF    ON  | 64 Sectors of  324 |     256     |   16384    |
    +------------+--------------------+-------------+------------+
    | ON     OFF | 36 Sectors of  578 |     512     |   18432    |
    +------------+--------------------+-------------+------------+
    | OFF    OFF | 35 Sectors of  594 |     512     |   17920    |
    +------------+--------------------+-------------+------------+
    | ON     ON  | 19 Sectors of 1096 |    1024     |   19456    |
    +------------+--------------------+-------------+------------+


 S1 Spindle Control Option
 -------------------------
 For those applications in which multiple devices share a common power
 supply, starting units sequentially i srecommended. With S1-6 off the
 drive will sequence up after both supplies are within tolerance.


 S1 RESERVED
 -----------
 S1-7 RESERVED.


 S1 Write Protect
 ----------------
 With S1-8 on, writing to the drive is prevented.

 Since this timeout can retard system performance, a 1 millisecond
 timeout priod is available if S1-7 is on. Note that the controller
 must also recognize this abbreaviated timeout if the system is to
 function correctly.


 J11 Remote Connector
 --------------------
 An optional connector attached to J11 allows certain switch
 selectable options of switch S1 to be controlled remotely. The
 corresponding positions on S1 must be off. (Positions S1-4/5/6/7 must
 always be operated at the S1 location.) Use the following list to
 replace S1 options:

 J11-1 & 2 replaces S1-1
 J11-3 & 4 replaces S1-2
 J11-5 & 6 replaces S1-3
 J11-7 & 8 replaces S1-8

 Notes On Installation
 =====================

 Termination
 -----------
 Every drive is shipped from PRIAM with a terminator installed to
 minimize reflections and ensure maximum data integrity. In a daisy
 chain of multiple drives, remove all terminators except the one in
 the final drive.


 DC power requirements
 ---------------------
 PRIAM's 5.25-inch drives require power from two dc voltages +5 and
 +12 volts. DC power is supplied via a 4-pin connector (AMP 350211-1
 Receptacle or equivalent).


 Actuator
 --------
 The read/write heads and servo head are mounted on a carriage,
 supported by precision ball bearings. A voice coil is attached to the
 carriage and mounted between permanent magnets. These components
 comprise the linear voice coil head mechanism. This mechanism
 provides the driving force to move the carriage for head positioning.
 The magnetic field in the gap between the magnets allows the
 acceleration of the carriage to be controlled by the voice coil
 current. Drive current for the coil is supplied by the actuator servo
 control circuit. Crash stops protect the heads if a malfunction
 causes the actuator servo circuit to lose control. When the drive is
 powered down, the carriage is driven to a non-data area (head
 landing zone) at the inner diameter of the disk, where it is locked
 to prevent head/media damage in case of shock during movement of
 equipment.

 Recommended orientation is either vertical on either side or
 horizontal with PCB down. In the final mounting configuration, ensure
 that operation of the four shock mounts is not inhibited.


 Shipping Damage Inspection
 --------------------------
 Priam disk drives are packaged to withstand normal handling in
 reusable shipping containers. It is the customer's responsibility to
 notify the carrier if shipping damage should occur to a drive.

 Note: When handling the drive while still in the shipping container,
 ensure that the container remains in the upright position indicated
 by the attached labels.

 Do not place drives in vertical positions closer than 2 to 3 inches
 apart to avoid hitting and breaking components.

 Shock and Vibration Precautions
 -------------------------------
 The drives must be handled in such a manner as not to exceed the Non-
 Operational Shock and Vibration limits.


 Mounting Holes
 --------------
 Eight mounting holes, four on the bottom and two on each side, are
 provided for mounting the drive in an enclosure. The size and
 location of these holes, are identical to the industry standard mini-
 floppy drive.


 J1/P1 Connector - Control Signals
 ---------------------------------
 Connection of J1 is through a 34-pin edge connector. The pins are
 numbered 1 through 34 with the even pins located on the component
 side of the PCB. Pin 2 is labeled. The recommended mating connector
 for P1 is AMP ribbon connector P/N 88373-3 or Molex 15-35-1341. All
 odd pins are ground.


 J2/P2 Connector - Data Signals
 ------------------------------
 Connection to J2 is through a 20-pin edge connector. The pins are
 numbered 1 through 20 with the even pins located on the component
 side of the PCB. The recommended mating connector for P2 is AMP
 ribbon connector P/N 88373-6, or Molex P/N 15-35-1201. Pin 2 is
 labeled.


 J3/P3 Connector - Power
 -----------------------
 DC power connector (J3) is a 4-pin AMP Mate-N-Lok connector P/N
 350211-1 mounted on the solder side of the PCB. The recommended
 mating connector (P3) is AMP P/N 1-480424-0 utilizing AMP pins P/N
 61314-4 (Strip) or P/N 60617-4 (Loose piece).


 J4/P4  Frame Ground Connector
 -----------------------------
 Faston AMP P/N 61761-2
 Recommended mating connector AMP 62187-1
 If used, the hole in J4 will accomodate a wire of size 18AWG max.

 General Information
 -------------------
 PRIAM 5.25-inch disk drives use advanced Winchester and micro-
 processor technologies to provide users with low-cost disk drives
 having high capacity, fast access, and long-term reliability. A
 linear voice coil positioner with track following servo enables the
 PRIAM 5.25-inch drives to position mini-Winchester type heads quickly
 and precisely. These low-force heads promote high data reliability.

 Advanced 5.25-inch, carbon overcoated, thin film, Winchester
 technology disks are driven by a brushless dc motor. The heads,
 disks, and head positioner coil and carriage are enclosed in a
 sealed, contamination-resistant chamber to ensure high data
 reliability.


 Media Defects
 -------------
 A media defect is some physical characteristic of the media which
 results in a repetitive read error when the drive is operating within
 specified operating conditions. Valid data must not be written over
 known media defects.

 All drives are chipped with a defect map, listing the following
 information:

 - Cylinder
 - Head
 - Defect Location
 - Defect Length (in bits)

 The defect location is specified in bytes ( 10 bytes) from the
 leading edge of index.

 The maximum number of defects allowed at the time of initial shipment
 is as follows:
                                       617   628   638
   - Defects per Drive (max allowed)    85   140   190
   - Defects per Surface (max allowed)  25    25    25

 There will be zero defects on track zero, heads 0-7 inclusive, at the
 time of initial shipment.


 Air Filtration Components
 -------------------------
 A self-contained recirculating filter supplies clean air through a
 0.3 micron filter to the sealed HDA. A separate filter allows for
 ambient atmospheric pressure equalization within the assembly without
 the induction of contaminants.
