Its fu}nction is to provide headselection, read pre-amplification, and write drivecircuitry.The dual microprocessor-controlled c}ircuit cardprovides the remaining electronic functions whichinclude: o Read/Write Circuitry o Rotary A}ctuator Control o Interface Control o Spin Speed Control o Dynamic BrakingAt power down the h}eads are automaticallyretracted to the inner diameter of the disk andare latched and parked on a landing zone that isinsid}e the data tracks.6.2 Drive MechanismA brushless DC direct drive motor rotates thespindle at 4498 RPM. The motor/spind}le assembly isdynamically balanced to provide minimalmechanical runout to the disks. A dynamic brakeis used to provide a f}ast stop to the spindlemotor and return the heads to the landing zonewhen power is removed.6.3 Air Filtration SystemTh}e head-disk assembly is a sealed enclosure withan integral 0.3 micron filter which maintains aclean environment for the hea}ds and disks.6.4 Head Positioning MechanismThe read/write heads are supported by a mechanismcoupled to a rotary voice c}oil actuator.6.5 Read/Write Heads and DisksData is recorded on 95mm diameter disks throughminiaturized 3370 type thin f}ilm heads.6.6 Customer OptionsC/DUp to two drives may be daisy chained togetherutilizing the 40 pin Task File connecto}r. Themaximum cable length is 18 inches. In order toinstall more than one drive, it is necessary toset a jumper option. } The C/D jumper is used todetermine whether the drive is a master (drive C)or slave (drive D). The drive is configured as }amaster (drive C) when jumpered and as a slavedrive (D drive) when not jumpered. (Refer todescription of -PDIAG signal fo}r furtherinformation on master/slave in Conner drives.)DSP & SSThis pair of jumpers determines the signals on pin39 of t}he interface connector. Jumper DSP SS Action - spindle synchronizat}ion signal X disabled on pin 39. - activity LED signal available on pin 39. - } spindle synchronization signal X enabled on pin 39. - activity LED signal disabled from p}in 39. - pin 39 floating. Master/slave in CAM compatible mode uses pin 39 ina time multiplexed ma}nner to indicate that a slavedrive is present. During power-on-reset or afterRESET is asserted, this line is asserted by t}heslave drive within 400 ms to indicate itspresence. The master drive allows up to 450 msecfor the slave drive to assert }-HOST SLV/ACT. -HOST SLV/ACT is deasserted by the slave drivefollowing its acceptance of the first validcommand or after }31 seconds, whichever comesfirst.Jumpers E1, E2, E3 E1 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}J3 ConnectorA drive select LED may be driven using twoalternative pins on this drive. Pin 39 can beused to drive the LED} if it is not configured forSpindle Synchronization. The 16-pin auxiliaryconnector (J3), pins 3 and 4 provide an opencoll}ector drive signal and a current limitingresistor connected to the other end of +5V.The spindle synchronization signal is}alternatively available on pin 2 of J3.7.0 Mounting Configuration The drive is designed to be us}ed in applicationswhere the unit may experience shock and vibrationsat greater levels than larger and heavier diskdrives.}The design features which allow greater shocktolerance are the use of rugged heads and media, adedicated landing zone, clo}sed loop servopositioning and specially designed motor andactuator assemblies.Ten base mounting points are provided to th}ecustomer. The drive is mounted using 6-32 x 1/8"max. insertion for the sides, and 1/4" insertionfor the bottom. The syst}em integrator shouldallow ventilation to the drive to ensure reliabledrive operation over the operating temperaturerange. } The drive may be mounted in any attitude.The system integrator should also allow 0.060inches (1.6mm) of free space and on} each side ofthe drive for head-disk-assembly (HDA) sway spaceif the drive is expected to need operating shockspecificatio}ns. If the disk drive is mounted fromsides, the mounting provisions should clear thebaseplate of the HDA. } } } 8.0 Measuring Drive Specifications8.1 Seek TimesThe timing is measured through the interface withthe }drive operating at nominal DC input voltages.The timing also assumes that the BIOS and PCsystem hardware dependency have be}en subtractedfrom timing requirements and that the drive isoperated using its' default translate parameters.Average seek }time is determined by averaging theseek time for a minimum of 1000 seeks of randomlength over the disk surface.8.2 Start} Time (Power Up)Numbers specified assume that spin recovery is notinvoked. If spin recovery is invoked, the maxcould be }40 seconds. Briefly removing power canlead to spin recovery being invoked.8.3 ShockDrives are subjected to specified G} level shockfor 11 milliseconds at 1/2 sine shock pulse. Thedrive meets specification without suffering non-recoverable R}EAD or WRITE errors or other damage.8.4 VibrationDrives are subjected to specified vibration levelsat 1/2 octave per mi}nute sweep sine. The drivemeets the specification without non-recoverableerrors READ or WRITE errors or other damage. } } 9.0 Electrical Description9.1 Power ConnectorPow}er is supplied to the drive through a standard4 pin DC power connector.The mating connector for the 4 pin connector isAMP} 1-480424-0 (Housing) and AMP 60619-4 (loosepiece) or 61117-4 (strip) contacts.The following table describes the 4 pin pow}erconnector pins: Pin Signal 1 +12V 2 GND 3 GND 4 } +5V 10.0 Host Interface10.1 DescriptionThe interface between the drive adapter and thedri}ve is called the Host Interface. The set ofregisters in the I/O space of the Host controlledthrough the Host Interface is k}nown as the TaskFile. The physical interface from the drive tothe host is implemented using a 40 pin connector.The pin de}scriptions follow.10.2 Interface ConnectorThe recommended mating connector is Molex P/N 15-47-3401 or equivalent. Two }drives may be daisychained on this connector, and the maximum cablelength is 18 inches.10.3 Signal LevelsAll signal le}vels are TTL compatible. A logic "1"is > 2.0 Volts. A logic "0" is from 0.00 Volts to.70 Volts. The drive capability of ea}ch of theinbound signals is described below.10.4 Signal ConventionsAll signals on the Host Interface shall have thepre}fix HOST. All negatively active signals shallbe further prefixed with a "-" designation. Allpositive active signals shall} be prefixed with a'+' designation. Signals whose source are theHost, are said to be "outbound" and those whosesource is} the drive, are said to be "inbound".10.5 Pin DescriptionsSignal Name Dir Pin Description-HOST RESETO } 01 Reset signal from the Host system which is active low during po}wer up and inactive thereafter.GND O 2 Ground betwe}en drive and Host.+HOST DATA I/O 3-18 16 bit bi-directional data bus 0-15 between the host and the } drive. The lower 8 bits, HD0-HD7, are used for register & ECC access. All }16 bits are used for data transfers. These are tri-state lines with 24 mA drive capability.GND }O 19 Ground between drive and Host.KEY N/C 20 An unused pin clipped on the drive and plugged o}n the cable. Used to guarantee correct orientation of the cable.RESERVED O 21,27,29GND O } 22 Ground between drive and host.-HOST IOW O 23 Write strobe, the rising edge of which clocks data }from the host data bus, HD0 through HD15, intoa register or the data register of the drive.GND O } 24 Ground between drive and host.-HOST READ IOR O 25 Read strobe, which when low enables data from a r}egister or the data register of the drive onto the host data bus, HD0 through HD15. The rising edge of -HOS}T IOR latches data from the drive at the host.GND O 26 Ground between the drive} and Host.+HOST ALE O 28 Host Address Latch Enable. A signal used to qualify the address lines. This sign}al is presently not used by the drive.GND O 30 Ground between the drive and host.+HOST IRQ14 }I 31 Interrupt to the Host system, enabled only when the drive is selected, and the host activates the -I}EN bit in the Digital Output register. When the -IEN bit is inactive, or the drive is not }selected, this output in a high impedance state, regardless of the state of the IRQ bit. The interrupt is set whe}n the IRQ bit is set by the drive CPU. IRQ is reset to zero by a Host read of the Status register or a write t}o the command register. This signal is a tri-state line with 8 ma drive capacity.-HOST IO16 I 32 Ind}ication to the Host system that the 16 bit data register has been addressed and that the drive }is prepared to send or receive a 16 bit data word. This line is tri-state line with 24 mA drive capacity.-HOST P}DIAG I 34 Passed diagnostic. At POR -PDIAG will be activated by the slave within 1 ms. I}f the master doesn't 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 on a power on reset. The master w}ill wait 14.5 seconds or until the slave deactivates -PDIA on power on reset before it goes not busy. The slave }will de-activate -PDIAG and go not busy, if it is not ready after the 14.0 seconds. Neith}er drive will set ready or seek complete until they have reached full spin speed and are ready} to read/write. During a software reset, -PDIAG will be activated }by the slave within 1 ms. If the master doesn't see -PDIAG active after 4 ms it will assume no} slave is present. The slave will not de-activate -PDIAG until it is ready to go not busy or 400 ms. The } master will only wait 450 milliseconds or until the slave deactivates -PDIAG before it activates -P}DIAG and goes not busy. The slave will not set ready or seek complete until those states are a}chieved. After reset, -PDIAG will be used for the diagnostic comma }nd in the following manner. It is output by the drive if it is the slave drive, input to the drive if it is t }he master drive. This low true signal indicates to a master that the slave has passed its inte }rnal diagnostic command. This line is only inactive high during execution of the diagnostic command.+HOST A0,A1, }A2 O 35 33,36 Bit binary coded address used to select the individual registers in the task fil }e.-HOST CS0 O 37 Chip select decoded from the host address bus. Used to select some of the Host acce }ssible registers.

Over the next fewda}ys we will be finishing the newMENU and tying up a few loose ends.We still have much work to completeon the manual but we} expect to beshipping in September.Outside beta testers have beenworking with SDX for almost 1 monthand it has been thor}oughly testedin house much longer than that.SDX includes 64K of the tightestmachine code ever written. This isall in ou}r special X cartridge whichallows you to plug a languagecartridge into the top. SDX hascomplete control over this cartrid}geallowing it to turn it on and offas desired.SDX offers the most free memory ofany available DOS! Presently MEMLOcan }be as low as $0E22 with nohandlers installed in an extendedmemory machine like the 130XE. 64Kmachines have MEMLO at $12D1}. Of course handlers push MEMLO up butMEMLO should still be lower thanSpartaDOS 2.3!High Speed data transfer is standar}don stock Indus GT drives, AtariXF551 drives, US Doubler enhanced1050 drives, and Happy 1050 drives.All densities are su}pported (single,dual, and double) single and doublesided drives are supported from 40to 80 tracks, 3 1/2, 5 1/4, and 8".}Hard drives on our Multi I/O arehandled with ease! The files perdirectory limit has been increasedto 1424 files! Support} has beenadded for hidden files along with anarchive bit for backup.SpartaDOS X now also supports the old800 computer! }An Axlon compatibleRAM upgrade is required for it to beuseful but it will actually workin a 48K machine with BASIC and ot}her relocatable languages. Withan AXLON type RAM board, MEMLO is below $1000! A 48K stock machinewill have a MEMLO just }above $3000. SpartaDOS X batch files now supportparameter passing. 16 I/O channelsare now in}cluded! 9 drive support allows D9: as a RAMDISK. Up to1 MEG Ramdisks are supported aslong as they conform to 'standard'}banking methods.ICD has developed ARC as part ofSpartaDOS X! This is very close tothe IBM version 5.22 of ARC by SEA.Ma}ny of the X cart routines areused for exceptional speed. SDX ARCis the fastest and most efficientfile compactor available} on an 8-bitcomputer. As a bonus, our ARC willDe-ALF your ALFed files!ARC Usage:ARC cmd[opt] arcfn [flist]Where "cmd}" is one of:a : add file(s) to archivem : move file(s) to archiveu : update file(s) in archivef : freshen file(s) in arch}ived : delete file(s) from archivex,e : extract file(s) from archivep : copy file(s) to screenl : list file(s) in archive}v : show storage method of file(s)Valid "opt" options are:b : retain backup copy of archives : suppress compression (sto}re only)w : suppress warning messagesn : suppress notes and commentsh : higher speed (screen off)g : encrypt/decrypt arch}ive entry (followed by password - must be last option)"arcfn" is archive filename(drive, path, and ext are optiona}l)"flist" is the list of files toextract, add, list, etc. in the archive.
