INTRODUCTION
The HORIZON is a versatile computer that can form the nucleus of either a single-user or a
multi-user configuration.
If you wish to create a single-user system, you will probably want to connect the HORIZON
to a terminal anda printer. These connections are very simple, and the instructions are given
below.
To incorporate one or more 18Mb hard disks into your computer system, follow the
directions in the North Star HD-18 User/Technical Manual.
To create a HORIZON-based computer system that can serve up to five users, follow the
directions in the North Star TSS-A or TSS-C Multi-User System Operation Manual,
SELECTING A SITE
You can place the HORIZON in almost any convenient location, although the computer
should not be exposed to extremes of temperature or humidity. Dust and dirt can also be
harmful to the HORIZON. In general, an environment that is comfortable for the operatoris
also suitable for the computer.
CONNECTING A TERMINAL TO THE HORIZON
The terminal you select must have an R5-232-C serial interface. Read the
instruction manual provided by the manufacturer to be sure that the terminal is
appropriate and that you observe all necessary precautions in handling it.
Follow the steps specified by the manufacturer to set these stand operating parameters:
9600 Baud
Full Duplex
No Parity
If the terminal cannot be set for 9600 baud, consult the HORIZON Computer System Manual
for instructions,
Position the HORIZON sa the back is facing you. The controls and connectors on the back of
the computer are labelled in Figure 2-1.

Use the same procedure to connect the other end of this cable to the MAIN or TERMINAL
port on the back of the terminal. Consult the manual for the terminal for the location of the
appropriate port.
CONNECTING A PRINTER TO THE HORIZON
A printer with either an RS-232serial interface or à parallel interface can be connected to the
HORIZON. A serial printer can be placed fifty or more feet away from the computer, while
the cable to a parallel printer can be no more than ten feet long.
Before connecting the printer and the HORIZON, read the instruction manual provided
with the printer. Follow the steps specified by the manufacturer to set these standard
operating parameters:
1200 Baud
Full Duplex
No Parity
If the printer you are using cannot operate at 1200 baud, consult the HORIZON Computer
System Manual for instructions.
Connect the computer and the printer before attaching the power cord to the computer.
Make sure that the power to the printer is turned off and the power cord is unplugged from
the wall socket.
2.4.1
Serial Printer
A serial printer can be connected to the HORIZON by either a flat ribbon cable or a round
cord. The printer cord or cable must end in the same kind of “D” connector shown in Figure
2-2, above.
Take the free end of the printer cable and
press the “D” shaped connector carefully
over the left serial port of the HORIZON
back panel shown in Figure 2-4. These
connectors anly match one way, so make
sure they are properly aligned.

SITUATING THE SYSTEM
After making the necessary connections, turn the HORIZON, the terminal and the printer
around so that the front of the components face you. Position the equipment so that you can
use it conveniently.
It is important to rest the HORIZON and the printer on different surfaces, so that printer
vibration does not affect the computer.
Situate the compter so you have easy access to the floppy disk drive(s) on the front of the
HORIZON, and can reach the power switch and reset switch on the back of the computer.
The HORIZON can be placed horizontally, as shown in Figure 2-8.
Computer System Configuration
Figure 2-8
The computer can also be placed on end, as shown in Figure 2-9. If you choose this
arrangement, note that the disk drive(s) MUST be positioned at the top of the unit, as
indicated.

The HORIZON operates on the standard electrical power supplied to offices,
schools and homes. The computer MUST BE ELECTRICALLY GROUNDED,
however.
AÍ HORIZON system components mustbe
powered from grounded (3-wire) A.C. out-
lets on the same circuit. Do not use any
plug adapters that eliminate the ground

Figure 2-11
The computer, terminal, printer, and any other peripheral devices you use MUST be
plugged into the same circuit or circuit breaker.
Other electrical equipment (such as copying machines, fluorescent lights or typewriters)
should NOT be plugged into the same circuit. The electrical noise generated by such
equipment can interfere with the proper operation of the computer system.
While a power strip is often convenient when several pieces of equipment are operating as a
system, take care not to overload the circuit. Do not use extension cords to power the
system.
Turn on the power to the computer. The
HORIZON on/off switch is located next to Turning on the HORIZON
the fan on the back panel. To turn the
power on, press the outer edge of the
switch in toward the computer (Fig. 2-12).

or particles land on a diskette they can
interfere with the storage and retrieval of
information. Likewise, if the diskette is
exposed to a magnetic field, its cantents
can be lost. A magnetic field can be gener-
ated by an electric typewriter or a magnetic
paper clip holder, for example. Figure 3-2
provides information on how to handle
your diskettes.

INSERTING A DISKETTE IN THE HORIZON
You can insert a diskette in the HORIZON with the computer turned on or off. For simplicity,
the following discussion assumes that the power is turned on in both the HORIZON and the
terminal.
Open the floppy disk drive that is closer to the center of the HORIZON by pulling the latch
toward you. The system diskette (such as the HORIZON-Diskette provided with the
computer) is always loaded into this floppy drive, which is either designated as drive #1, or
drive A, depending on the program you are using.
Slide the system diskette into the drive
apening. The diskette should be positioned
as shown in Figure 3-4, with the small
rectangular notch on top and the label
facing toward you.

Push the diskette in gently. If you encounter more than slight resistance, puli the diskette
out carefully and start again. The diskette is flexible and you may damage it if you force it into
- the floppy disk drive.
Push the diskette into the drive until you hear a click and feel the diskette hit the back of the
slot. This indicates that the diskette is properly positioned in the disk drive.
With the diskette fully inserted, close the disk drive latch.
‘BOOTING’ THE HORIZON
Press and release the reset switch on the |
back panel of the HORIZON (Fig 3-5). This Booting the HORIZON
is called “booting” the computer, and it
starts the process of transferring the pro-
gram from the diskette into the internal
memory.

Figure 3-5
When the reset switch is activated, the red indicator light on the floppy disk drive comes on,
the disk drive motor begins to whir, and the program prompt appears on the terminal
screen.
You are now ready to begin work with your HORIZON.

USING YOUR HORIZON
If your HORIZON has two floppy disk drives, the drive toward the center of the computer
(#1) is used for system diskettes, and the drive toward the outer edge (#2) is used for data
diskettes. Use the same procedure described in Section 3.2 to insert a data diskette in drive
#2,
If your HORIZON contains a Winchester hard disk drive as well as a floppy disk drive, the
hard disk is permanently installed in the computer. You do not interact directly with the hard
disk, as you do with the floppy diskettes.
The hard disk is used for storing programs and data. The floppy diskettes enable you to load
new programs onto the hard disk, and to transfer programs and data between computers.
The floppy diskettes also serve as a backup medium for the hard disk.
Perhaps the single most important part of working with a computer is learning to make
regular backup copies of all your programs and data. Systematic backup is crucial! to guard
against information loss due to operator error, equipment malfunction, or other causes. The
manuals for the programs you use will explain exactly how to back up your diskettes or hard
disk.
ENDING A WORK SESSION
The manual for the program you are running will explain how to exit from that program.
Always wait until the red indicator light on the floppy disk drive has gone out
before removing a diskette from the drive. You may damage the diskette if you
attempt to remove it while the drive is still operating.
Lift the latch on the floppy disk drive and carefully remove the diskette. Replace the diskette
in its protective envelope and store it upright, in an appropriate container.
At the end of the day, turn off the power to the HORIZON.
