 The CP2034 and CP2064 drives are designed to operate either as a
 Master drive (C Drive) or a Slave Drive (D Drive). This feature is
 dependent on two drive settings; the status of hardware Jumper E1 and
 the firmware setting of a feature bit. When (E1) is closed, and the
 feature bit is set, the drive will assume the role of a Master Drive.
 When E1 is open, and the feature reset, the drive will act as the
 Slave. In single drive configurations E1 must remain in the closed
 position.

 The drive may be mounted in any attitude!


 Recommended Mounting Configuration
 ----------------------------------
 This CP2034 and CP2064 are designed to be used in applications where
 the unit may experience shock and vibrations at greater levels than
 larger and heavier disk drives.

 The design features which allow greater shock tolerance are the use
 of rugged heads and media, a dedicated landing zone, closed loop
 servo positioning and specially designed motor and actuator
 assemblies.

 Four (4) side mounting points and four (4) bottom mounting points are
 provided to the customer. The drive is mounted using 3mm x 0.5mm
 thread screw. The screw insertion depth should not exceed 4mm into
 the mounting holes. 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.


 Interface Connector
 -------------------
 The CP2034 and CP2064 drives have a 44 pin right angle interface/
 power connector mounted on the PCB. The recommended mating connector
 is DuPont part number 69764-044 or equivalent. The maximum cable
 lenght is two feet.


 Magnetic Field
 --------------
 The externally induced magnetic flux density may not exceed 6 gauss
 (DC - 700KHz) or 1.0 gauss (700KHz - 1.5MHz) as measured at the
 drive surface.


 Acoustic Sound Emission
 -----------------------
 Pressure: 34 dB(A) max at 1 meter.

 Key Features
 ------------
 The CP2034 and CP2064 are a high performance 2.5 inch low-profile
 disk drives with formatted capacities of 32 and 64 megabytes
 respectively. Both drives have 19 ms average seek time and are
 designed to operate on IBM PC/AT or equivalent computers.
 The drives feature a low 5V power requirement and high shock resist-
 ance, enabling battery operation in a portable environment.

 - 2.5" Form factor

 - Single 5 Volt supply

 - Low power requirements

 - High performance rotary voice coil actuator with embedded servo
   system.

 - Single connector for power & interface

 - Run length limited code (one of seven or two of seven)

 - High shock resistance

 - Internal air filtration system

 - Sealed HDA

 - Automatic actuator latch over data free landing zone during standby
   mode or power-down

 - Microprocessor-controlled diagnostics routines that are auto-
   matically executed at start-up.

 - Automatic error correction and retries

 - Block size 512 bytes

 - PC AT Interface

 - 1:1 sector interleave

 - Automativ read look ahead

 - 32K Buffer

 - Master/Slave



 Universal Translate Mode
 ------------------------
 Conner has established a Universal Translate Mode which enables the
 user to configure the drive in an AT environment to any cylinder,
 head, and sector configuration desired. The translate configuration
 is limited only by the maximum capacity of the drive. Upon initial
 power up to the drive it will default to a predetermined configura-
 tion shown below:

          Cylinders        Heads       Sectors
 CP-2034     411             4           38
 CP-2064     823             4           38

 After the drive is ready, the host system may issue INIT DRIVE PARMS
 COMMAND (command code 91H) to alter the translate configuration
 (number of heads and number of sectors per track). The drive para-
 meters will then be saved in EEPROM for subsequent drive operations.


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

       +----------------------------------+--------+
       |Physical track to track      max. |   5 ms |
       |Logical                      max. |  10 ms |
       +----------------------------------+--------+
       |               Average msec. typ. |  19    |
       |               Average msec. max. |  40    |
       +----------------------------------+--------+
       |Latency                msec. avg. |   8.7  |
       +----------------------------------+--------+
       The timing is measured through the interface with the drive
       operating at nominal DC input voltages. The timing also assumes
       that:
             - BIOS and PC system hardware dependency have been
               subtracted from timing measurements.

             - The drive is operated using its translation parameters.


       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.


 Functional Description
 ----------------------
 The CP2034 and CP2064 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 preamplification, and write drive circuitry.

 The single microprocessor controlled circuit card provides the
 remaining electronic functions which include:

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

 At power down or the start of STANDBY MODE or SLEEP MODE the heads
 are automatically retracted to the inner diameter of the disk and
 are latched and parked on a landing zone that is off the data tracks.


 Drive Mechanism
 ---------------
 A brushless DC direct drive motor rotates the spindle at 3486 RPMs.
 The motor/spindle assembly is balanced to provide minimal mechanical
 runout to the disks and to reduce vibration of the HDA. A dynamic
 brake is used to provide a fast stop to the spindle motor when power
 is removed, or upon initiation of STANDBY MODE.


 Air Filtration System
 ---------------------
 Within the sealed enclosure, a 0.3 micron filter which provides a
 clean environment for the heads and disks.


 Head Positioning Mechanism
 --------------------------
 The read/write heads for the CP2034 and CP2064 are supported by a
 mechanism coupled to the voice coil actuator.


 Read/Write Heads and Disks
 --------------------------
 Data is recorded on 95mm diameter thin film disk through micro-
 miniature thin film or MIG heads.


 Error Correction
 ----------------
 The CP2034 and CP2064 drives use a Reed-Solomon code to perform
 error detection and correction. The error correction polynominal is
 capable of correcting one error burst with a maximum of 22 bits or
 2 error bursts of up to 11 bits each, per 512 byte block. Single
 bursts of 11 bits or less are corrected with no performance degrada-
 tion.


 Reliability and Maintenance
 ---------------------------
 MTBF                     100,000 hours POH
 MTTR                     10 minutes typical
 Preventive Maintenance   None
 Component Design Life    5 years


 Safety Standard
 ---------------
 The CP2034 and CP2064 disk drives are designed to comply with
 relevant prodcut safety standards such as:

 - UL 478, 5th edition, Standard for Safety of Information Processing
   and Business Equipment, and UL 1950, Standard for Safety of
   Information Technology Equipment

 - CSA 22.2#154, Data Processing Equipment and CSA 22.2#220, Inform-
