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

 Mounting Orientation
 --------------------
 The MiniScribe 9000 Series uses industry-standard mounting for
 5-1/4" Winchester Disk Drives. The 9000 Series are designed to be
 used in applications where the unit may experience shock and
 vibration at greater levels than larger and heavier disk drives.

 The drive may be mounted in any attitude.

 The 9000 drive is mounted using 6-32 UNC screws 1/4" maximum
 penetration. The customer must allow adequate ventilation to the
 drive to insure reliable operation.

 In as much as the drive frame acts as a heat sink to dissipate heat
 from the unit, the enclosure and mounting structure should be
 designed to allow natural convection of heat around the HDA and
 outer frame. If the enclosure is small or if natural convection is
 restricted, a fan may be required.


 Daisy Chaining the MiniScribe 9000 Drives
 -----------------------------------------
 Up to seven 9000 Series drives may be connected to a single host
 controller/formatter. Control signals at J1 are transmitted via
 standard, daisy-chain interconnection. Data signals at J2 are trans-
 mitted via radially connected data-transfer lines.

 Note: Interface terminators RP4 and RP17 are installed only in the
 last physical drive in the control chain. Maximum number of drives =
 7.


 J4  SCSI Connector
 ------------------
 J4 is a 50-pin straight solder pin connector on the printed circuit
 board. This cable connector is used to send and receive information
 from the SCSI Host Adapter with keyed slots between pins 3 and 5, 23,
 25 and 27, and 47 and 49.

 Recommended Mating Connector: Burndy FRS50BF-8P or equivalent.

 Recommended cable is a Belden 50 pin flat cable, part number 9LS8050
 or equivalent.


 J3  DC Power Connector
 ----------------------
 J3 is a 4 pin keyed connector on the printed circuit board. DC power
 (+5V and +12V) is supplied to the drive via this connector.

 Recommend connector: AMP 350543-1
 Pins:                AMP 350078-4

 Note 1: Equivalent of the above are permissible.
 Note 2. Suggested wire size 18 AWG.


 Electrical Interface
 --------------------
 SCSI uses single-ended drivers and receivers which allow a maximum
 cable length of 20 feet (6 meters) from the first to the last device
 (up to 8 devices) on the bus.

 All assigned signals are terminated with 220 ohms to +5 volts and
 330 ohms to ground at each end of the cable. Both two (2) terminator
 networks on the 9380S are removable.

 All signals driven by the drive are open collector and have the
 output characteristics as follows.

 Signal Assertion                  0.0 VDC to 0.8 VDC
 Max. Driver Output                48mA (sinking) at @ 0.5 VDC
 Signal Negation                   2.5 to 5.25 VDC

 All signals received by the drive shall have the following input
 characteristics.

 Signal True                       0.0 V DC to 0.8 V DC
 Maximum Total Input Load          -0.4 mA @ 0.4 V DC
 Signal False                      2.5 to 5.25 V DC
 Minimum Input Hyteresis           0.2 V DC

 Introduction
 ------------
 The MiniScribe 9000 Series of disk drives are low cost, high
 capacity, high performance random access storage devices utilizing
 5 1/4" this film disks as storage media. Each disk surface employs
 one moveable head to access the data tracks. The 9000 Series
 features capacities of 380 megabytes (unformatted storage capacity).
 The 9000 disk drives utilize advanced 3380 Whitney-type head flexures
 and sliders which allow closer spacing of disks, allowing a higher
 number of disks in a standard 5 1/4" package.

 Media Defect Criteria (as shipped from MiniScribe)
 --------------------------------------------------
 Maximum Defects*             275
 2 bytes in length
 Cylinder zero defect free

 *A single defect is defined as being less than 2 bytes long. A
 multiple defect is defined as 2 bytes or longer, or as a track with
 more than 1 single defect.


 Caution/Warning
 ---------------
 The Miniscribe drive is a precision product. During handling the unit
 must not be dropped, jarred or bumped. Otherwise, damage to the heads
 and disks may occur. When the drive is removed from the Miniscribe
 shipping container and not immediately secured within a chassis
 through its shock mounts, it must be stored on a padded, grounded,
 antistatic surface.

 Failure to comply with the above procedure will render null and void
 all warranties.
