SCOPE
This guide is designed to take you step by step through the
procedures to install and initialize your Corvus disk system
for Xerox 820 computers.
This
guide details only the installation and initialization
procedures.
It does not contain explicit explanations or
descriptions of the Corvus disk system and software.
Further information concerning your Corvus disk systein
and associated software can be found in the Corvus
Systems User Guide for CP 1M Computers.

CONVENTIONS
The word IIType" is used throughout this guide to mean
that two or more characters are to be entered at the
computer keyboard. The form ofa "Type" statement is
as follows:
Type RUN SYSGEN 1RETURN I
Keytop symbols such as ISPACE I within or at the end ofa
statement to
be typed represent a single typewriter key to
be pressed. When a keytop symbol is used, press the key to
which it refers.
The word "Press" is used throughout this guide to mean
that a single letter, number, or symbol is to be entered at
the computer keyboard. Examples:
Press Y

HARDWARE SETUP
To use your Corvus disk system with a Xerox computer,
the following minimum hardware and software is required:
o Xerox computer with 64K RAM
o Single floppy diskette drive
o Corvus Hard Disk System for Xerox computer with
CORVUS XR-H UTIUTIES diskettes
o CP1MVersion 2.2 diskette
Xerox 820 Computer System
with Corvus Disk System

1. Power off all equipment.
2. Place the disk unit on a flat surface, on its base. Be sure the
disk drive has adequate ventilation. Also, protect the disk
from strong electronic fields by not placing power cords or
other electro-magnetic field generating equipment on top
of the drive container.
Since the Corvus disk system is a precision instrument, it
must be handled carefully. The disk drive must not be
operated when the unit is upside down, on its side, or if the
long direction is at an incline.
To
ensure cool running equipment, the airflow slots
located
at the rear of the drive container should not be
blocked. Also, avoid putting the unit in a sealed container
(such as in a box or drawer).

3. Flip all of the red drive controller switches to the left, which
is the normal position for each of them.
Approximately two inches
(5 cm) below the indicator
lights,
the front panel protrudes slightly. The four switches
are located directly
beneath the lights, and up under the lip
ofthe protrusion.

4. Verify that the voltage setting for the drive matches the
local voltage (100v, 120v, 220v, or 240:v). The drive works
with 50
or 60 Hertz power in any of the voltage settings.
The voltage setting, fuse,
and local voltage must match. Any
type of mismatch here causes damage to the drive hardware.
7

Voltage Selection and Fuses
The AC power cord connector and fuse are found at the
bottom right of the back panel on all drive models. To
change
the voltage selection, flip the small circuit board and
install the proper fuse as follows:
D Slide open the clearplastic cover door, pull the fuse-pull
lever to
the left, and remove the fuse.
D Use long-nose pliers to carefully pull the voltage circuit
board out of the fuse housing. To select the proper
operating voltage, position the circuit board so that the
desired voltage displays on the top left side of the board.
Push the board firmly into the slot.
D Do not re-insert the fuse you removed if you have chosen a
different voltage setting from
the one you received with the
drive. Select
the correct slow blow fuse using the
following table:
Disk Drives:
100 or 120 volt
220 or 240 volt .2.0
amp
1.0 amp
D To return the fuse to its receptacle, push the fuse-pull lever
to the right
and insert a fuse into the holder. Slide the clear
plastic cover
door to the right to expose the AC power
cord connector.

5. Connect the 34-pin flat cable to the disk drive port labelled
PROCESSOR on the rear bezel. The cable must exit
downward, with the red stripe on the right, as you look
directly
at the rear of the drive. (Note that this cable must
not be coiled because coiling increases signal distortion.)
6. Remove the cover from the Xerox 820 computer by taking
out the two screws in the top cover.
7. Locate the 40-pin connector labeled }8 on the Xerox 820's
main circuit board. Attach the 40-pin flat cable to the }8
connector. The cable exits toward the rear of the computer
with the colored stripe to the right as viewed from the rear.
Use caution to insure that the pins on the main circuit
board line up with all the holes on the connector.

Connected to Xerox 820 Computer

8. Locate the 20-pin connector labeled J11 on the Xerox 820's
main circuit board. Attach the 20-pin flat cable to the J11
connector. At the connection, the colored stripe of the
20-pin cable faces toward the front of the·computer. Use
caution to insure that the pins on the main circuit board
line up with all the holes on the connector. The cable is
then folded back to exit toward the back of the computer.
9. Replace the cover to your Xerox 820 computer.
10. Tum on the computer. (Whenever the computer and drive
are connected, the computer should be turned on first, then
the Corvus disk drive.)
11. Connect the AC power cord to the disk unit and to a power
receptacle. Turn on the drive.
After approximately 40 seconds,
the READY light should
be on, the BUSY and FAULT lights should be off, indicating
that
the disk system is ready.
The
power switch is located in the lower right hand
corner of the back panel.
If the disk system does not become ready after one
minute, then flip the RESET switch, which is the rightmost
switch
on the front of the drive cabinet
12. If the drive is not ready after you have flipped the RESET
switch,
see the "Troubleshooting" section of the CORVUS
SYSTEMS' USER GUIDE FOR CP/M COMPUTERS.

INITIALIZA TION
FOR CP/M
This procedure will create CP1M areas on the Corvus drive.
The floppy drives use volumes
A: and B:, volumes from C:
on are on the hard drive.
After initialization is completed it will
be necessary to
run the C LI NK program each time the computer is turned
on. The CLINK program you run depends upon the model
drive
being used.
-For the Model 6 run C LI NK2 FV
For the Model 11 run CLlNK2TN
For the Model 20 run CLlNK2TW
Before initializing your Corvus disk, copies of the Corvus
Xerox Utility diskettes
should be made, using the
PIP command.
1. Tum on your computer after hardware setup.
