Introduction
This manual will guide you through each step of the
assembly of your Data-1000 personal computer. Even if
you are anew computer user, you can rest assured that
you have made awise decision in buying this system
because you will not only be saving money, but you will
also begin to gain important "hands-on" experience which
will be of great benefit to you in the future. The detailed
instructions in this manual will also ensure that you get
your new computer running with aminimum of trouble.
Although newcomers to the computer world will find this
system ideal for their first step, experienced hands will
also appreciate the flexibility that they are allowed in con-
figuring the system to their own special needs. The moth-
erboard which is used is PC/XT compatible and is switch-
able from ordinary 4.77MHz clock speed to 1OMHz Turbo
speed. Moreover, awide variety of expansion cards are
available from Datatech or other manufacturers for inter-
facing the system with your choice of peripherals. And in-
stallation of up to two floppy disk drives and two hard
disks is asnap.
This system includes acardboard box of miscellaneous
parts, acase, apower supply, floppy disk drive and hard
disk installation plates, akeyboard, akeylock key, a
power cord and amotherboard. Other parts of the system
such as floppy disk drives or hard disks, expansion cards
and external peripherals are to be selected by the user.

Software
The software that your system will use falls into two cat-
egories. First there is the operating system, the language
of the computer that tells the system what to do. The oper-
ating system that this computer uses is Microsoft Corpora-
tion's MS-DOS®, the world's most widely used operating
system for PC/XT compatibles. This means that finding
application software will be as simple as going to your
nearest PC store.
Application software is what you use for work and play.
Aspreadsheet program is an example of this kind of soft-
ware.

Motherboard installation
Before installing the motherboard, refer to the manual
which accompanies it to make any changes to the config-
uration that you may require. You are now ready to install
the motherboard. First, find the cardboard box of miscella-
neous parts and from it select the following:
Take the plastic fitting and snap it into place on the
motherboard as shown below. The pointed end should
4show on the side of the board that the chips are on.

Functions of panel indicators and switches
Now that you have connected the panel indicators and
switches, you should understand something about their
functions:
Keylock The keylock is used to enable or disable the
keyboard. By disabling the keyboard, the user ensures
that anyone who does not have akey will be unable to
use the computer. Unlocking the keylock enables the
keyboard.
Power LED The power LED indicates whether the
power is on.
Reset The reset switch restarts the computer from the
RAM test stage. If you encounter any problems while
using unfamiliar software, you can always start from the
beginning by pressing the reset button.
Turbo LED The turbo LED indicates operation at
turbo speed.
Hardware switch The hardware switch changes
operation speed between turbo and normal.

Installation of power supply
Installation of the power supply is relatively simple.
First, find the section of the case where the power supply )
will be installed. .

Connecfions
Ali connections from the system unit to external periph-
erals and apower source are at the back of the case. As
always, you should be certain all power switches are
turned off before connecting or disconnecting anything.
When attaching cables to connect any device, including
the system unit, to something you should always connect
the cable to the device first and then to the appropriate
outlet.
Power supply
The power supply has two connectors, one supplies
power to monitors, the other connects to the main power
source. See the following illustration.
Monitor power source
To main power source

If your monitor's power cord has aplug that matches
the configuration of the power supply receptacle then you
can plug the monitor into the system unit. If not, you will
need to connect it to astandard electrical outlet.
You should first attach the system power cord to the
connector indicated in the diagram and then to a
grounded outlet.
The power supply connector is located at the upper
right corner of the motherboard. To connect the power
supply to the motherboard, find the two 6-pin connectors
from the power supply and plug them into the connector
on the motherboard. There is only one way to plug in the
power supply connectors but you must make sure the
black wires are to the inside (see the illustration below).

Drive installation
3The number of floppy disk drives to be installed is
)‘usually optional. Up to two floppy disk drives and two hard
disks may be installed in the system unit. The advantage
of more disk drives and hard disks in your system is
having more information and application software at your
fingertips. This means that you will have more "power"
and will not have to go through the time-consuming
process of disk-swapping, especially if you use one or two
hard disks.
The floppy disks drives can be used with single-side,
double-side or high density floppy disks. They can also be
used to format disks in these three modes.

First, connect the floppy disk controller cable and one of
the four cables from the power supply. The power cable is
simple to connect: just plug it in. The shape of the plug
ensures that no mistakes will be made. For the floppy disk
controller cable, you must first have afloppy disk con-
troller card. You should refer to the appropriate card's
manual for installation instructions. One edge of the
ribbon cable is marked with acolor line. This specific line
side of the connector should be at Pin 1when attached to
the card. Pin 1is clearly marked on the card. The same
procedure is followed for asecond disk drive.
Next, attach the two metal plates included to the sides
of the disk drive(s) as shown below:

Note that the plate on the right side as you see in the
picture is slightly smaller. Follow the same procedure to
connect the second disk drive.

Holding the floppy disk drive(s) in place, turn the case
on its side and screw the disk drive in. There are four
holes. Note that the two openings in the central part of the
case give access to two sets of screw holes each. The
holes farther away from the center of the case are for the
floppy disk drive. When you finish this operation, you will
have completed the installation of the floppy disk drives.
15

Installation of hard disks
The installation of ahard disk is similar to that for a
floppy disk drive. In other words, the cables should be
connected “first, then ametal plate attached to the hard
disk and finally the hard disk attached to the case. Amore
detailed description follows.

Connect the power cable and the hard disk controller
cables. Note that there is only one possible way to con-
nect the power cable and hard disk cables owing to the
shape of the connectors, so it is impossible to make a
mistake.
The two hard disk controller cables are of different
sizes: the red wires on the cables should be connected
toward the central portion of the case.
Next, connect the metal plate as shown in the illustra-
tion on the next page.

Keyboard installation and usage
You are now ready to install the keyboard. Look at the
back panel of your system unit. Referring to the picture
below, you may now plug the cable from your keyboard
into the keyboard connector at the back.
