Federal Communications Commission (FCC) Statement
Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and it not installed and used
in accordance with the instructions, may cause harmful interference to radio communica-
tions.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Any special accessories needed for compliance must be specified in the instruction manual.
Warning: A shielded-type power cord is required in order to meet FCC emission limits and
also to prevent interference to nearby radii and t&vision reception. It is essential that only
the attached power cord be used.
Use only shielded cables to connect I/O devices to this computer.
You am cautioned that changes or modifications not expressly approved by the party
responsible for compliance could void your authority to operate the equipment.
This digital apparatus does not exceed the Class B limits for radio noise emissions from
digital apparautus as set out in the radii interference regulations of the Canadian
Department of Communication.
Le Présent appareil numérique n'émet pas de bruits radioélectriques dépassant les limites
applicables aux apparels numériques de Class B preescrites dans le réglement sur le
brouillage radiélectrique édicté parte Ministére des Communications du Canada.
ii
Warning
• Your warranty be voided if you open your system unit case
up to reconfigure the system.
• If you wish to reconfigure the computer at any time, ensure that
the power is turned OFF before changing any hardware settings, such as DIP switches or jumpers.

1-1 Introduction
This manual will guide you through the setup of your computer and
provide the information necessary to tailor the system to fit your needs.
lf you are a novice, you will have your computer up and running with a
minimum of fuss. You will also gain valuable handson experience by
following the easy step-by-step instructions. If you are an advanced
user, you will appreciate the affordable power of this system.
The 386-based mainboard provides superlative performance and complete compatibility with software written for the Intel ‘86 family of CPUs.
The system uses a cache memory subsystem providing a small
amount of fast memory (SRAM) and a large amount of slow memory
(DRAM).
-fast enough to support burst cycles and to complete bus cycles with
no wait states. The cache memory provides high performance at a
cost approaching that of DRAM.
Quality, flexibility, and functionality are the key design features of your
system. This system provides optimum performance at an affordable
price.

Chapter 7: System Overview
The control panel provides several useful functions which are explained below. You are likely to use the front panel frequently, so let’s
start there.
Reset Button
The reset button allows you to restart the system without turning the
power off.
lf you encounter any problems while using unfamiliar software, you can
always restart quickly from the RAM test stage by pressing the reset
button. Note, however, that any data which have not been saved to disk
will be lost.
Figure 1-4: Front Panel
Turbo Button
The Turbo button allows you to change the operating speed of the
microprocessor to accommodate software requirements. Some
software applications must be run at a slow clock speed.
lndicator Lights
These lights indicate the operation status of your computer. The red
LED comes on when the hard disk is being accessed. The green LED
is lit when the power is on. The yellow LED comes on when Turbo clock
speed is activated.

Keylock
The keylock enables or disables the keyboard. In the unlock mode the
keyboard is activated. In the lock mode the keyboard is disabled to
deny unauthorized uses access to the computer.

System Power Switch
The system power switch is located on the control panel.
You should always be certain that the power is turned off before
modifying the hardware configuration in any way.

1-8 Rear Panel
The rear panel has all the connections that lead from the system unit
to external peripherals and the power source. Turn off all power
switches before connecting or disconnecting cables/wires! En-
sure that cables/wires are attached to the external device first and
connected to the outlet unit later. Turn the system unit power switch off
before you plug the power cable into an electrical outlet.

You will also need to connect your monitor to the system unit at a
female display port in one of the expansion slots as shown on the
previous page.
To attach the monitor cable to the video port, plug the cable into the
port and screw the cable connector down securely.
Your computer gives you a wide range of video options to meet your
needs.
You have a wide choice of the following video standards.
— MGA (Monochrome Graphics Adapter) also referred to as
