Drive Addressing and Interface Termination NOT USED J2 J1 J3 Power 1 1 Power (under ------- board) Terminator DA1 DA2 DA3 (Component side) W5 W4 W3 W2 W1 RN1 Interface Terminator The Interface Terminator factory installed at RN1 will provide proper termination for the interface lines. When daisy-chaining multiple drives, leave the terminator installed only in the last physical drive on the daisy chain; remove the terminator from each of the other drives. In most PC/AT installations, the C: drive is actually at the end of the cable and should retain the terminator. DA1, DA2, DA3 Drive Address Jumpers The drive address jumpers are identified as DA1, DA2 and DA3. Address selection is binary, as shown in the table below. The ESDI controller's documentation will specify the drive address to use. Drive Select Jumpers Address DA3 DA2 DA1 ------- --- --- --- 1 out out in 2 out in out 3 out in in 4 in out out 5 in out in 6 in in out 7 in in in "Drive address 0" (no jumper at DA1, DA2, or DA3) is a "deselect" (i.e., no drive selected). Drives are factory configured as Drive Address 1. For many multiple drive installations, each drive must have a unique address. An exception is that for every drive in a PC/AT installation, verify that the only Drive Address is at DA2; move the jumper if necessary (the special twisted interface cable that is generally used takes care of assigning a unique address to each drive). PC/AT controller can typically support a maximum of two drives. W5 Selects the Spindle Control Option. W5 selects the spindle a control option. If W5 is installed, the drive waits for a Start Spindle command(after power is applied) to start the spindle motor. If W5 is not installed (the factory default configuration),the drive automatically starts the spindle motor at power-on. W5 is not installed for PC/AT applications. W1 Selects the Sectoring Mode. Micropolis 1664 Manual (http://www.franken-online.de/ymmv) Page 2 of 10

If W1 is installed, the drive operates in the soft-sectored mode. If W1 is not installed (the factory default configuration), the drive operates in the hard-sector mode. W1 is not installed for most PC/AT in applications. W2, W3, W4 Sector Size and Number Options The number of bytes per sector may be specified using the Set Bytes Per Sector command or by selecting a default sector configuration with jumpers W2, W3, and W4 as follows: Jumpers Sectors Bytes/Sector W4 W3 W2 Per Track Formatted Unformatted --- --- --- --------- --------- ----------- out out out 53 512 588 ------------------------------------------------------------- * out out in 54 512 576 ------------------------------------------------------------- out in out 28 1024 1116 out in in 14 2048 2232 in out out 7 4096 4464 ----------------------- RESERVED ---------------------------- in in out 97 256 321 in in in 1 31,248 31,248 * This is the default (factory installed) configuration and is recommended for PC/AT applications Micropolis 1664 Manual (http://www.franken-online.de/ymmv) Page 3 of 10

Recommended orientation is vertical on either side, or horizontal with the Device Electronics board down; other mounting orientations may be used provided the ambient air temperature around the drive is kept at or below 50øC (122øF). Inasmuch 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 frame. If the enclosure is small and/or natural air flow is restricted, a fan may be required. In any case, no point on the HDA assembly should exceed 62øC (143øF). Mounting Screws 4 per side 6-32 UNC-2B x 0.10 deep (thru hole). 4 on bottom 6-32 UNC-2B x 0.22 deep Caution: To avoid restricting HDA sway space, the mounting screws must not penetrate the outer surface of the side mounting holes more than.10 (+.00, -.03) inch or the bottom mounting holes by more than.20 (+.00, -.03) inch. Torque applied to the screws must not exceed 8 in-lbs. Control Signal Connector J1 J1 is a 34-pin board-edge connector. The signals on this connector control the drive and transfer drive status to the host controller. Recommended Cable: 3M Scotchflex 3365/34 or equivalent. Mating connector: AMP 88373-3 (key slot between pins 4 and 6). J2 Data Tranfer Connector J2 is a 20-pin board-edge connector. The signal on this connector contain read or write data.

Connectors J4 and J5 are provided for grounding; system characteristics determine the proper ground connection. Up to seven disk drives may be connected to a single host controller/formatter. The control signal at J1 are transmitted via the standard, daisy-chain interconnection. Micropolis 1664 Manual (http://www.franken-online.de/ymmv) Page 8 of 10

The data signals at J2 are transmitted via radially connected data-transfer lines. Interface Electrical Characteristics Connector J1 The Control Signals control the drive and transfer drive status to the host controller. The signals are low-true at the interface, high-true into drivers and out of receivers, and have the following logic levels. Driver: 7438 or equivalent Receiver: 74LS14 or equivalent True = 0.0 VDC to 0.40 VDC @ I = -48 milliamps (maximum) False = 2.5 VDC to 5.25 VDC @ I = +250 microamps (open collector) Interface Cable Length 10 feet (3 meters) maximum Connector J2 All interface data transfer signals are differential in nature. One TTL control signal and four TTL status signal are also provided at Connector J2. The signals are high true into drivers and out of receivers and have the EIA RS-422 levels shown. Driver: AMD 26LS31 or equivalent Receiver: AMD 26LS32 or equivalent High = +2V Low = +0.5V Adjustments and Maintenance The 1660 disk drives requires no adjustments or periodic maintenance; additionally, no mechanical adjustments are required to prepare a system for handling or shipment. Field-Replacable Components The concept of repair by replacement of complete functional components is utilized in the 1660 Series, resulting in an MTTR of less than 15 minutes. Interface The 1660 disk drives are pin- and function-compatible with the Serial mode of the Enhanced Small Device Interface (ESDI) for 5 1/4-inch Winchester disk drives. In the Serial mode, interface signals (control, data, and status) are transmitted serially via handshaking request/acknowledge signals. Media Defects Media defects are physical characteristics of the media which result in repetitive read error when a functional drive is operated within specified operating conditions. At the time of manufacture, a media test system evaluates every drive and identifies each media defect location. The defects are logged on a label affixed to the drive. The defective areas are identified by head address (HD), cylinder address (CYL), and number of Bytes From Index (BFI). A printed listing of the defects is also shipped with each drive. In addition to listing the defects on the label and the printout, the defects are also mapped on the drive. The defect list is written for each data surface. The list Micropolis 1664 Manual (http://www.franken-online.de/ymmv) Page 9 of 10

is written on the corresponding surface in Sector 0 at three cylinder locations: 1) The maximum cylinder (1779). 2) The maximum cylinder minus 8 (1771). 3) A special cylinder accessed as "Cylinder 4095" (FFFh). Note: The cylinder at the address of 4095 is a drive-unique location. This is in compliance with the industry-standard ESDI specification. Do not attempt to write to Cylinder 4095. Micropolis specifies that all 1660 drives shall have no more than one defect per megabyte of unformatted capacity. Additionally, Cylinder 0 and the cylinder at 4095 shall be defect-free at the time of shipment.
