It uses a 44/50 pin connector, such as the Dupont Mini-Tek series P/N 86455-350. The signal levels are TTL compatible unless otherwise noted. Reserved pins should be left unconnected. Below is a description of the pinout definition. -+-----+ RESERVED | A B| RESERVED RESERVED | C D| RESERVED KEY | E F| KEY REMOVED RESET- | 1 2| GND DD7 | 3 4| DD8 DD6 | 5 6| DD9 DD5 | 7 8| DD10 DD4 | 9 10| DD11 DD3 |11 12| DD12 DD2 |13 14| DD13 DD1 |15 16| DD14 DD0 |17 18| DD15 GND |19 20| KEY (REMOVED) |21 22| GND DIOW- |23 24| GND DIOR- |25 26| GND IORDY |27 28| CSEL |29 30| GND INTRQ |31 32| IOCS16- DA1 |33 34| PDIAG- DA0 |35 36| DA2 CS1FX- |37 38| CS3FX- DASP- |39 40| GND (MOTOR) 5VDC LOGIC |41 42| 5VDC (MOTOR) GND LOGIC |43 44| RESERVED --+-----+ CSEL Pin 28 Cable Select ------------------------ This Cable Select signal is used to configure a drive as either Drive 0 or 1. +---------+---------------+ |CSEL | Drive address | This signal is pulled up internally +---------+---------------+ with a 10K resistor. |GROUNDED | 0 | +---------+---------------+ |OPEN | 1 | +---------+---------------+ PDIAG Pin 34 Drive Diagnostics ------------------------------ Asserted by drive 1 to indicate to drive 0 that it has completed diagnostics.

It is built into the HDA base casting and not just installed as with other drives. The spindle motor bearings are the same size as those used in 2.5" drives, yet the MiniStor drive has one third the mass being held by those bearings. The larger bearings size results in a greater surface area supporting shock loads. The reason for the large bearings is to prevent any damage from large shock loads. ********************************************************************** F E A T U R E S ********************************************************************** MINISTOR AT ATTACHMENT PRODUCT MANUAL 830000500 VER. 1.1 5/1994 Introduction ------------ The MiniStor AT Attachment drives are 1.8" subminiature ruggedized high performance disk drives designed for the portable and mobile computing environment. Key Features ------------ ImpacSAFE(TM) Built-in technology to prevent data loss or corruption from shock and vibration. Rugged and Reliable 200G operating and non-operating shock resistance ensures reliable operation in demanding portable computing environments. High Performance 16ms average seek time, 6.72ms average latency and advanced caching algorithms for fast data access. Electro-Mechanical Latch ------------------------ The MiniStor latch is a static bistable latch. In other words, the latch can be in either of two stable conditions, which require no other forces to remain in those conditions. Below is a brief description of the latch operation from power-up to power-down. When power is supplied to the drive the latch coil is energized. The EMF generated overcomes the preload of the engaged latch, and the latch rotates to the stable open position. The coil is then deenergized. The latch is held in the open position by magnetic attraction. On power down, the servo circuit is given an autoretract command. As the actuator moves toward the landing zone the actuator arm mechanically engages the latch to the stable closed position. Shock Sensor ------------ The Shock Sensor uses an electromechanical transducer that turns off write current preventing data corruption, when the drive is subjected to a high g force.
