Initial Setup
You
will
find
your computer
system
easiest
to
use
if
all
the components
are
located
in
the same general area. A
good,
solid
work
surface near
a
power
source and a telephone
will
prove
best.
Refer
to
the instructions
on
the inside
top
flap
of
the
shipping carton
and
unpack
the
computer.
Place
it
on
the
work
surface
selected and
posi-
tion
it
so
you
are
looking
at the
back
panel.
NOTE:
Because
of
the number
of
video
options
available,
the
computer
system
does not include a
video
card.
However,
you
must have a
video
card
installed
in
your computer
for
proper operation.
If a
video
card has been installed
by
your dealer, continue
with
the
initial
setup
of
your
system.
If
no
card
is
installed,
Appendix A of
this

The Back Panel
The following switches
and
connectors are located on the back panel as
shown in Figure
1.1.
tine
Select Switch - This switch
is
used to select between
115
VAC
and 230
VAC.
You
should never use this switch unless, during initial
setup, you are in
an
area serviced by a 230
VAC
power source. (Check
local electrical codes.) Changing the setting on this switch should be done
only by qualified individuals. When the line voltage
is
changed, for exam-
ple,
115
VAC
to 230
VAC,
the line cord plug must be changed to the
proper type and voltage rating.
On/Off
Power Switch - The power switch
is
located on the left side
of
the back panel. Make sure the switch
is
in the OFF position before
you plug your computer into
an
outlet.
Power Cord Connector - When connected, the power cord supplies
power to the computer.
Keyboard Connector - A 5-pin
"DIN"
connector provides the necessary
signals for connection with the computer keyboard.
Serial Connector - The necessary EIA-standard RS-232 signals for con-
nection to a serial printer
or
other serial device are provided through
this 9-pin connector. A special cable
is
needed to connect a DB-25 output
to
this connector.
Parallel Connector - This 25-pin connector provides the necessary
parallel signals for connection to a Centronics-type parallel printer
or
other
parallel output device.

Initial
Setup
If
your system components are not in their normal operating positions,
move them to their final position now. Reconnect any cables.
Up
to this
point, you should not have made any power connections.
CAUTION:
This computer system
is
designed to operate on either of two
different
AC
line voltages, either
115
VAC
at 60 Hz
or
230
VAC
at 50
Hz.
Before connecting the computer, make sure
it
is
rated for the voltage
available in your area. The computer
is
set at the factory for
120
volts,
the standard voltage in the United States. To change the voltage rating,
contact your authorized repair
facility.
• Before you connect any
of
your computer's components to
an
AC
power source, turn all power on/off switches
off.
The computer
has
a detachable power cord. Refer to Figure
1.3
and
plug
the appropriate
end
of the power cord into the computer.
Do
not attach
the other
end
at this time.
With
multiple power cords involved, you may want
to
use a switched
multiple outlet box
or
power strip to turn on (or
off)
all system components
at the
same
time.
If
you do use a switched outlet box
or
power strip,
make sure
it
is
properly rated for your system's power needs (for
115
volt systems,
10
amperes; for 230 volts, 5 amperes).

Powerup
and
Self-Tests
Normal Powerup
CAUTION: Before you turn on your computer system, be sure the
cardboard shipping insert has been removed from the disk drive.
The computer system's power may be turned on in any sequence, however,
never turn your system's power
on
or
off
with a disk
in
the floppy disk
drive; remove the disk
first.
There are two suggested sequences
for
turning on your system:
• One switch operation through a switched multiple outlet power box
or strip. The one switch on the box
or
strip
will
control the entire
computer system simultaneously.
• For most applications, apply power
to
your monitor
first,
then the
computer. Finally, turn on any other peripherals attached to your
computer system.
After the system
is
turned on, a number
of
things
will
happen: a small,
quiet fan
will
start; a light on the disk drive
will
come on; and the drive
will
make some sound as the "read/write heads" move back and forth.
Factory assembled computers are set
to
"autoboot" (automatically load
a disk operating system from a floppy or Winchester disk) when they
are shipped. One
of
the lights on the disk drives
will
come on and remain
on
in
a computer set for autoboot. If autoboot is started, a disk must
be placed in the drive
and
the door shut within about 20 seconds.
If
you want
to
reset the system by turning
it
off
and then on again, wait
at least
five
seconds before turning the computer on.
Page
1.7
Initial
Setup
Self-Tests
When
you
turn
on
your computer,
it
executes a series
of
internal
tests
to
check that everything
is
working
correctly.
These
tests
serve
several
important
functions.
First,
they
verify
that
all
of
the
circuits
are
in
a starting
configuration.
Second,
the
tests
check various
functions
of
the
computer
so
it
will
operate properly.
When
the tests are
finished,
the
computer
will
let
you
know
it
is
ready
to
run
by
displaying the opening
message,
or starting the automatic
boot
procedure (autoboot).
If
some
portion
of
the equipment
fails
to
operate
correctly,
the computer
will
attempt
to
display
an
error
message.
These messages and more
infor-
mation
on
the
initial
diagnostics
are included
in
the
In
Case

section
in
Chapter 3
of
this
manual.

Initial
Setup
Keyboard
Keyboard Lock
The left side
of
the front panel includes a keyboard lock that
is
independent
of
the power switch.
When the key
is
in the unlocked (clockwise) position, the computer
is
fully
operational. In the locked (counterclockwise) position, the key can
be removed and the keyboard
is
disabled. The cover
is
locked on the
chassis - when the keyboard
is
locked.
An
extra key
and
a card referencing the key
number
and security code
are included in the box with your computer. These materials should be
kept in two different places.
If
a key gets lost, the extra key
or
the reference
card can
be
taken to a locksmith for a duplicate
key.
NOTE:
Zenith Data Systems can not duplicate a key according
to
the
serial
number
of
the computer. Keep your extra key
and
reference card
in
secure locations.
The keyboard of your computer contains 84 keys that are discussed in
the following pages.
Whenever you hold down any
key,
except the SHIFT,
CTRL,
ALT,
CAPS
LOCK,
SCROLL
LOCK,
or
NUM
LOCK,
it
will
start repeating. The rate
at which
it
repeats
will
gradually increase as you hold the key down.
Alphabetic Keys
Your personal computer has the standard 26 letters
of
the alphabet ar-
ranged as they are
on
a typewriter. These keys allow you
to
enter either
upper-
or
lowercase letters; hold down either SHIFT key
or
push the
CAPS
LOCK
key to obtain uppercase letters.
The
CAPS
LOCK
key
is
a push-to-engage, push-ta-release
key,
and affects
only the alphabetic keys. A light in the key indicates whether the feature
is
on (lit)
or
off
(unlit).

Control Keys
The control keys are used in combination with other keys to perform
certain functions. Combinations using these control keys are explained
in
Table
1.1.
ESC
- The escape key
is
used to stop the execution of a program/function
or
to
perform special functions when you press it in sequence with another
key.
For example,
if
you want to enter ESC-E, press the
ESC
key,
release
it,
and then press the E
key.
NOTE: When you do not want your computer system
to
autoboot a disk,
press the
ESC
key during autoboot (while the disk light
is
on). The system
prompt and message
will
appear in the upper-left corner
of
the monitor's
screen.
CfRL - The control key performs special functions by pressing it with
another key simultaneously. For example,
if
you want to enter the
CTRL-C
combination, press
and
hold the CfRL key and then press the C
key.
ALT - The alternate key
is
used to enter special commands by pressing
it
and another key at the same time. For example,
if
you want to enter
the
ALT-A
combination, press and hold the ALT key and then press the
A
key.
NOTE: The
CTRL,
ALT,
and DEL combination
will
reset your computer.
All
three keys must be pressed at the same time
to
return the computer
to
the power-up point.

The SETUP
Program
The SETUP program serves as a reference, giving the computer informa-
tion about your system's configuration. The information you enter about
your system
is
kept in memory for all future uses and can easily be changed
if
you alter your configuration.
Type
SETUP
after the MFM-200 system prompt
(-
» and press the
RETURN
key to run the program.
If
your computer
is
set for autoboot,
press the
CfRL
and
ALT keys simultaneously and while holding them
down, press the
INS
key to get to the system prompt.
When the setup screen first appears, the standard selection in each
field,
or grouping,
is
already highlighted on the screen with a rectangular-shaped,
reverse-screen image.
You
can make your own selections by highlighting
the data which matches your system's configuration.
You
can move up, down,
left,
or
right between fields using the arrow
keys.
Within each field, except the time and date field, use the space
bar and
BACKSPACE
key
to
move between entries.
To
make a selection, move to the desired field and highlight the entry
that describes your system. This selection
will
be locked in when you
move
to
the next field.
The message area at the bottom of the screen
will
provide help and error
messages.
TIME
The time
and
date are the only entries that need
to
be typed in.
All
.
the other data
is
selected using the highlighted cursor.
The system's clock
is
battery-operated and
will
run continuously, even
when the computer is turned
off.
Therefore, you do not need
to
enter
a new time
and
date each time you turn the system on.
Page
1.17
Initial
Setup
The time clock operates
on
a 24 hour basis. For example, 2 p.m.
is
14:00
and
11
p.m.
is
23:00. The format for entering the time
is
hh:mm:ss, where
hh
is
the hour,
mm
is
the
number
of
minutes past the hour, and ss
is
the
number
of seconds into the minute.
The time must be entered in a two-digit format. For example, the hour
entry for 9 a.m.
is
09. It
is
not necessary to enter the colons between
the hours, minutes,
and
seconds. They
will
be entered automatically.
Example: 4:35 a.m.
is
entered as 043500.
4:35 p.m.
is
entered as 163500.
If the time is not entered correctly, an error message
will
appear at the
bottom of the screen. The cursor
will
not move past the entry until a
valid time
is
entered.
If you make a mistake while typing, use the
BACKSPACE
key to return
to
the position where you made the mistake and
type
over
it.
After entering the time, press the
RETURN
key
to
move
to
the date entry.
DATE
The date entry format
is
mm/dd/yyyy, where
mm
represents the month,
dd represents the day of the month, and
yyyy
represents the year. Note
that the numbers representing the month and day consist
of
two
digits,
while the year
is
represented by a four-digit number.
Example: March 21,1986
is
entered as 03211986.
It
is
not necessary to enter the slashes between the month, day, and
year. They
will
be
entered automatically. After entering the date, press
the
RETURN
key.
The time
and
date fields are the only ones which are entered using the
RETURN
key.
In the remaining fields, your selection
will
be locked in
when you move from a field using the arrow
keys.

Winchester Drives
If you are using
one
or
more Winchester disk drives, you need to select
a drive type for each
of
them. Refer
to
Table
2.1
for the different types.
For a factory-installed drive, the type can be determined by the code
on the back panel. This code
is
arranged in 3-digit sets, each representing
one drive.
• The first 3-digit set represents the drive identifier code for floppy
driveA.
• The second 3-digit set represents the drive type identifier code for
either floppy drive B
(if
present)
or
Winchester drive
O.
• The third 3-digit set represents the drive type identifier code for
either Winchester drive 0
or
Winchester drive
1,
depending on
whether floppy drive B
is
installed.
• The fourth 3-digit set represents the drive type identifier code for
Winchester drive
1.
The maximum
of
12
digits indicates that four
drives are installed in the computer.
Position the highlighted marker over the drive
number
and, using the
space bar
and
backspace key, scan through the drive types
(1
to
15),
until you find the one which matches the data for your drive.
If
you
do not have a Winchester drive, select
NOT
PRESENT.
