System Overview
A brief introduction to the Zip Subsystem and key features.
We at Micro Analytic welcome you to a new and useful addition to you Solid State Logic equipment.  The 610-S Zip Disk Subsystem is an advanced computer controlled storage system which connects directly to your console and uses existing SSL software.   The Zip Disk Subsystem appears to the SSL console to be a Bernoulli Drive, but, unlike a Bernoulli cartridge, the Zip disks  are physically smaller, more economical and can provide additional safety  in shipping and handling.

 standard Features

•	Available in the same form factor as existing Bernoulli drives (2U high 
•	Universal International power supply
•	Dual drives for duplication of disks 
•	On site firmware upgrades

 Advanced Features

When equipped with a serial interface, the following options are available to the 610-S:
•	Advanced options include local operation for disk copy independent of the console computer
•	Remote diagnostic option via modem or terminal
•	Unique data recovery options
•	Automatic data backup

Operation 
	Operation of the 610-S is simple and convenient.  Simply insert a ZIP cartridge into the drive.  In a few moments , the drive will spin up and be ready for use.  To remove the disk, simply press the round button on the lower right side of the disk drive and the cartridge will eject automatically.  
	Software operation of the 610-S is referenced in the SSL user’s manual as the removable cartridge drive.  Please refer to this manual for console operations.
Cartridge Handling Issues
In general, it is best to eject any disks from the drives prior to power down.  On occasion, it is possible that a disk may not eject should the power fail while a disk is operating.  Should this occur, try the following:
1)	Should the disk not eject, be sure that it is not currently engaged by the software, and try again. 
2)	Perform a power down, power up sequence of the 610-S only, and then try the eject button.

TECH MANUAL ONLY:
	Should the disk remain jammed in the unit, there is a manual eject mechanism on the drive.  You will need to open the unit up to gain access to the rear of the ZIP drive.  Using an unfolded paper clip, insert the wire into the hole located on the upper right corner on the rear of the Zip Drive.  This will operate the release mechanism and the disk should pop out.

Installing Product Updates
	One of most convenient and useful features of your 610-S Zip disk subsystem is the ability to upgrade the internal firmware on site.  Periodically, updates to the system will be made available on a ZIP disk.
Installation Procedure	
	First, ensure that you have a Firmware or Feature Upgrade disk in hand.  You should also check the revision number and date of the disk be sure that it is the version that you planned to install.
	Next, be sure that the console is not performing any disk operations. This includes using the 3.5” floppy drive system.  Should the system attempt to access any drive, it will prevent the automatic firmware install process or possibly abort one that is in progress.   You can ensure that the system is idle by either placing power to the 610-S system only, or, by allowing the SSL console to boot, then, power the 610-S off and follow the instructions below.
	With a FIRMWARE ZIP DISK loaded in the B drive,  power the 610-S on.  The disk will automatically spin up and the upgrade process will begin.  When the 610-S has completed and verified the installation, the disk will eject automatically.  Your system is now ready for use.

Notes:
1)	While the upgrade process in effect, the system will not allow you to eject the disk.
2)	Should the process be interrupted due to power failure or inadvertent disk access by the console operator, the 610-S will revert to an earlier revision.  You should repeat the  installation to establish the new firmware.

TECH MANUAL ONLY:
	The 610S does not perform version checking on the firmware disk.  Therefore, you can revert to an earlier version and not know it.  This is allowed such that should a new release not perform at a given location, you have the ability to re-establish an earlier version.
	Some firmware installation processes copy themselves into a “clean” area of Flash memory, leaving the prior firmware revision intact until verified.  Therefore,  in most instances, should the new firmware load be interrupted, the unit will revert to the previous up-grade version.  There is a small operating window that will not allow this to occur under certain power failures.  In such a case, the firmware will revert to the shipped version.
	Emergency firmware override:
Should the world go wrong, and the firmware load fail so badly that you cannot load any firmware, there is an out.  Open the case and locate JP-N.  Short pins X,Y as shown in the diagram, then power up the unit with the firmware disk installed in DRIVE B.  This will force the system to load the data and install the firmware.

ADVANCED FEATURES

The following section describes features that are planned and will only be available to those 610-S units optioned with the serial interface.  The operation of these options will require the use of an external CRT or PC connected to the serial port.
If you cannot use an external CRT at your location, you may want to consider using model 610-R, which contains a built in front panel display  complete with selection switches  that will support and selection the advanced operation features without an external CRT. 
The 610-R can also be optioned for the serial port should you need to support a remote CRT or computer connection .  Please refer to the 610-R manual for details.

Feature Programming:
	Using a CRT or other serial  display device attached to the 9pin connector on the rear of the 610-S, advance features can be accessed.
Functions:
Load New Firmware
	Forces load of firmware installed in Drive B.
	With a FIRMWARE ZIP DISK loaded in the B drive,  this feature allows replacement or upgrade of the operating software used by the ZIP Disk Subsystem.  
Copy Disk
	This performs a copy of the ZIP disk in the A unit to the B unit.
Format Disk 
	This performs a low level format of a ZIP disk .
Date Stamp Options
	You can place a date stamp on the disk or read an existing stamp.
Automatic Data Backup & recovery options
	You can restore a duplicate copy of the data on the drive to another disk for review if the automatic data copy option has been enabled.

 **NOTE** these features are not yet implemented  and will be available as an optional upgrade.  These features will be available on units with the serial option only**

Remote diagnostic
	You can enter into a monitor mode or request execution of various diagnostics to the ZIP drive.  *on certain systems equipped with the SASI card, you can perform diagnostics on the system CPU , memory, memory dumps, etc.
Remote data transfer
	You can transfer the data from the ZIP disk to another 610-S system using the serial link and a modem.

**NOTE** these features are not yet implemented  and will be available as an optional upgrade.  These features will be available on units with the serial option only**

Installation

Typical Wiring configurations:
Consoles with 3 ½” Floppy Drives:
	For systems using 3 ½” floppy drives, the existing drive cable sources from the SSL computer to the floppy drives.  This cable remains in place as wired.  There should be a square terminator installed on the connector adjacent to the existing cable.  Remove this terminator from the floppy unit.  You will no longer need this terminator.
	Using a new dual 50 pin “D” type cable, connect the cable from the empty connector on the 3 ½” floppy drives to the 610-S Zip Disk Subsystem connector marked “SCSI INPUT”.  Your hardware installation is now complete .  
You will need to change the software configuration of your console.  Please refer to the section "Software Considerations".

Consoles with 3 1/2" Floppy Drives and Bernoulli Drives:
For a system with existing Bernoulli drives, we recommend using the 610-R model.  This model will support both the ZIP and Bernoulli drives simultaneously.  However, if you have no longer need to access the Bernoulli disks ,the 610-S will suffice.
To replace the Bernoulli drives with the 610-S, unplug the Bernoulli cable  from the 3 1/2" drive and replace it with a dual 50pin D-sub cable [C1002].  Plug the other end of the cable into the 610-S SCSI INPUT connector.  Your entire installation is now complete. No software configuration changes are needed.

Consoles with 8" floppy Drives and Bernoulli Drives:
If you have 8" drives on your system, your Bernoulli Drives are connected directly to the SSL computer. This connection should utilize a cable that has two flat dual 50 pin connectors on it.  You must replace this cable with one that has a flat dual 50 pin connector on one end, and a 50 pin D-Sub style on the other. (Refer to Chapter 6 cable # 1234).  Unplug the cable from the SLL computer, and install the flat dual 50 end of the new cable in its place.   
Install the D-Sub side of the  new cable to the rear of the 610-S unit.  Your installation is now complete.

Note: 
For systems with existing Bernoulli drives, we recommend using the 610-R model.  This model will support both the ZIP and Bernoulli drives simultaneously.  However, if you have no longer need to access the Bernoulli disks ,the 610-S will suffice.

Note: 
If you do not have an existing Bernoulli installation and you have 8" floppy drives in your console, then it is possible that you do not have the SCSI interface installed in your console.  Micro Analytic manufactures this interface and you may purchase this interface directly from us.  Please reference part number 70-04210-00.  You may need further technical assistance to determine if you need this interface and how to install it .

Software Considerations

If you have installed the ZIP drives on a console that was previously operating the Bernoulli drives, you are already done!!
The 610 system appears exactly like a Bernoulli to the console.  The drives are known as drive units A or B.  In the SSL manuals, the Bernoulli drives are also referenced as the data cartridge drive units, the 20Mb cartridge or simply Bernoulli.  
 If your system did not previously support the Bernoulli drives, you will need to re-configure the console.  In doing so, follow the instructions supplied from SSL for installing the removable 20Mb cartridge drives.
