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

 C/D Jumper
 ----------
 Up to two drives may be daisy chained together utilizing the 40 pin
 Task File connector. The maximum cable length is 18 inches. In order
 to install more than one drive, it is necessary to set a jumper
 option. The C/D jumper is used to determine whether the drive is a
 master (drive C) or slave (drive D). The drive is configured as a
 master (drive C) when jumpered and as a slave drive (D drive) when
 not jumpered.


 DSP & SS Jumper
 ---------------
 This pair of jumpers determines the signal on pin 39 of the interface
 connector.
 +--------+------------------------------------------------------+
 | Jumper |         Action                                       |
 |DSP| SS |                                                      |
 +---+----+------------------------------------------------------+
 | X |    | - spindle synchronization signal disabled on pin 39. |
 |   |    | - activity LED signal available on pin 39            |
 +---+----+------------------------------------------------------+
 |   | X  | - spindle synchronization signal enabled on pin 39.  |
 |   |    | - activity LED signal disabled from pin 39           |
 +---+----+------------------------------------------------------+
 |   |    | - pin 39 floating                                    |
 +---+----+------------------------------------------------------+


 Master/slave in ATA compatible mode uses pin 39 in a time multiplexed
 manner to indicate that a slave drive is present. During power-on-
 reset or after RESET is asserted, this line is asserted by the slave
 drive within 400 ms to indicate its presence. The master drive allows
 up to 450 msec for the drive to assert -HOST SLV/ACT. -HOST SLV/ACT
 is deasserted by the slave drive following its acceptance of the
 first valid command or after 31 seconds, whichever comes first.


 Jumpers E1, E2, E3
 ------------------
 E1 CLOSED  Jumper in disables spin-up at power-on. The drive will
            automatically spin up when it receives a command which
            accesses the drive.

 E2 UNUSED

 E3 UNUSED


 Conner Master/Slave
 -------------------
 The drive is equipped with a -C/D jumper. To select the drive as the
 master, in a two drive or ported system, or a single drive, the -C/D
 jumper should be installed. If the jumper is not installed, the drive
 will configure as the slave. The -PDIAG line is used as the slave
 present signal to the master in the following way.

 At power on time -PDIAG will be activated by the slave within 1 ms.
 If the master does not see -PDIAG active after 4 ms it will assume no
 slave is present. -PDIAG will remain active until the slave is ready
 to go not busy or 14.0 seconds after a Power On Reset. The master
 will wait 14.5 seconds or until the slave deactivates -PDIAG on
 Power On Reset before it goes not busy. The slave will deactivate
 -PDIAG and go not busy, if it is not ready after the 14.0 seconds.
 Neither drive will set Ready or Seek Complete until they have reached
 full spin speed and are ready to read and write.

 During a software reset, -PDIAG will be activated by the slave within
 1 millisecond. If the master does not see -PDIAG active after 4 ms it
 will assume that no slave is present. The slave will not deactivate
 -PDIAG until it is ready to go not busy or 400 ms. The master will
 only wait 450 ms or until the slave deactivates -PDIAG before it goes
 not busy. The slave will only wait 450 ms before it activates -PDIAG
 and goes not busy. The drive will not set Ready or Seek Complete
 until those states are achieved.

 After Reset, -PDIAG is used in its normal diagnostic function during
 the diagnostic command.

 A drive select LED may be driven using two alternative pins on this
 drive. Pin 39 on the interface connector can be used to drive the LED
 with a current limited 5 volt supply if it is not configured for
 Spindle Synchronization. The 16-pin auxiliary connector (J3), pins 3
 and 4 provide an open collector drive signal and a current limiting
 resistor connected to +5V.

 The spindle synchronization signal is also available on Pin 2 of J3.

 Key Features
 ------------
 The CP30204 Cougar is a high performance 3.5 inch low-profile (1.0
 inch high) 213 megabyte (formatted) disk drives with 12 ms average
 seek time, that is designed to operate on an IBM PC/AT or equivalent
 in translate mode. The drives feature fast 12 ms average seek time,
 low 6.7 ms average rotational latency and high shock resistance.

 Because the drive contains the Task File within its control logic, it
 requires a simplified adapter board to operate. Conner Peripherals
 has developed an adapter board to be used in conjunction with the
 drive on an AT or equivalent system.

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

 - Auto translate feature, allowing operation as any drive type (not
   exceeding its capacity)

 - 1,7 run length limited code

 - High shock resistance

 - Sealed HDA

 - Automatic actuator latch against inner stop upon power-down.

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

 - Automatic error correction and retries

 - 512 bytes block size

 - Emulates IBM Task File and supports additional commands

 - Up to two drives may be daisy-chained on the AT interface

 - 256KB segmentable cache with LRU caching algorithm

 - Redundancy on entire data path from data reception

 - Single burst ECC on-the-fly

       |physical                          |   3    |

       +----------------------------------+--------+
       |Latency                msec. avg. |   6.7  |
       +----------------------------------+--------+
       The timing is measured through the interface with the drive
       operating at nominal DC input voltages.

       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 drive 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 dual microprocessor-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 latched and parked on a landing zone
 that is off the data tracks at the inner diameter of the disk.


 Drive Mechanism
 ---------------
 A brushless DC direct drive motor rotates the spindle. 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
 ---------------------
 The head-disk assembly is a sealed enclosure with an integral 0.3
 micron filter which maintains a clean environment for the heads and
 disks.


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


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


 Error Correction
 ----------------
 The drive uses a Reed-Solomon code to perform error detection and
 correction. The polynominal is able to detect a single burst of up to
 51 bits in length or up to three bursts each of which may be up to 11
 bits in length.

 The error correction capability of the polynomial is a single error
 burst with a maximum length of 22 bits or two independent error
 bursts of up to 11 bits or less is corrected "on-the-fly" with no
 performance degradation. The miscorrection probability using this
 "on-the-fly" error correction is superior to the detection capability
 of the traditionally used 56 bit computer generated code.


 Reliability and Maintenance
 ---------------------------
 MTBF                     150,000 hours (POH) based on comparison of
                          similar Conner products.
 MTTR                     10 minutes typical
 Preventive Maintenance   None

 prodcut safety standards such as:

   and Business Equipment, and UL 1950, Standard for Safety of
