SCOPE
This guide is designed to take you step by step through the
procedures to install and initialize your Corvus disk system
for TRS-80
Model II 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 system
and associated software can be found in the CORVUS
SYSTEMS USER GUIDE FOR CP/M COMPUTERS.

CONVENTIONS
The word "Type" is used throughout this guide to mean
that two or more characters are to be entered at the
computer keyboard. The form of a "Type" statement is
as follows:
Type RUN SYSGEN (ENTER I
Keytop symbols such as ISPACE I within or at the end of a
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:

HARDWARE SETUP 1
To use your Corvus disk system with a TRS-80 Model II
computer,
the following minimum hardware and software
is required:
D TRS-80
Model II computer with 64K RAM
DOne 8" floppy diskette drive
D
Corvus Hard Disk System for TRS-80 Model II computer
with CORVUS T2-H UTILITIES diskettes
D
CP/M Version 2.2 diskette

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-magentic 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 or at an incline.
To
ensure cool running equipment, the air flow 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 em) below the indicator
lights,
the front panel protrudes slightly. The four switches
are located directly beneath the lights, and up under the lip
of the protrusion.

4. Verify that the voltage setting for the drive matches the
local voltage (100v, 120v, 220v, or 240v). 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.

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:
Voltage Selection and Fuses
D Slide open the clear plastic 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 2.0 amp
220 or 240 volt 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 .
