The Epson® Equity® 386/25 PLUS is a high-performance
personal computer which offers exceptional speed and
convenience in a compact design. The computer’s 25 MHz
80386 microprocessor makes all your programs run extremely
fast, even when supporting multitasking operations.
Your system includes 2MB of internal memory, a built-in ‘VGA
(video graphics array) display adapter, built-in parallel and serial
interfaces, an IBM® PS/2™ compatible mouse port, and four
standard option slots (three 16.bit and one B-bit). These
interfaces allow you to connect most of your peripheral devices
directly to the computer, so you do not have to install option
cards. You can use the option slots to install additional devices,
such as a modem or a networking card.
Your computer can support up to three internal drives: either
two diskette drives and one hard disk drive, or one diskette drive
and two hard disk drives.
The Equity 386/25 PLUS offers several other features to
enhance the speed and versatility of your computer:
❏ Memory caching. Portions of your system memory are
copied to a high-speed cache buffer so your computer can
access programs and data very quickly.
❏
Shadow RAM. Your system ROM (read-only memory) and
video ROM are copied into the computer’s 32-bit RAM
(random access memory) to further accelerate system
performance.
❏
Extended and super-extended VGA modes. The built-in
VGA adapter and VGA drivers (included) provide graphics
resolutions up to 1024 x 768 in 16 colors or 640 x 480 in
256 colors on compatible VGA monitors.
Introduction 1
Optional Equipment
You can easily upgrade your computer by installing additional
memory and adding optional devices compatible with the IBM
Personal Computer, PC XT,™ or PC AT.“’
By adding memory modules to the main system board, you can
expand the computer’s memory up to 16MB. Memory modules
are efficient because they eliminate the need to use an option
slot to add memory to your system. Your computer can also
access memory on modules faster than memory on an option
card.
You may also want to install a math coprocessor in your
computer to speed up calculations in certain application
programs. You can add an Intel ® 80387 (25MHz) or a
Weitek®3167 (25MHz) math
by installing a Weitek dual-coprocessor adapter. Check with
your authorized Epson dealer to see which options are available.
coprocessor; or you can add both
Operating Systems and Other Software
You probably have a version of MS-DOS@’ to use with your
computer. Epson has enhanced MS-DOS by adding two timesaving utilities-HELP and MENU-that make it easier to use.
The HELP program lets you display information on the screen
about any MS-DOS command. MENU provides an easy way to
run many of these commands.
2 Introduction
You can use virtually any application program designed for the
IBM PC, PC XT, PC AT, or compatible computers on your
Equity 386/25 PLUS. You may also use powerful 32-bit
software-such as Microsoft Windows/386™-with your
computer.
VGA Utilities
Epson has provided special VGA utilities and device drivers
that you can use with certain standard VGA monitors and
multi-frequency monitors. Using these drivers, you can take
advantage of extended and super-extended VGA features such

6 lntroduction
Chapter
1
Setting Up Your System
Setting up your Equity 386/25 PLUS personal computer is easy.
Just follow the eight steps in this chapter. As you set up your
computer, you may want to leave this manual’s back cover
foldout open so you can refer to the illustrations identifying the
different parts.
Choosing a Location
1
Setting Up Your System
1-1
Before you set up your computer, it’s important to choose a safe,
convenient location that provides the following:
❏ A large, sturdy desk or table. The surface should be strong
enough to support the weight of your system and all of its
components. Select a location that allows plenty of space so
you can work comfortably.
❏ A flat, hard surface. Soft surfaces like beds and carpeted
floors attract static electricity, which can erase data on your
disks and damage the computer’s circuitry. Soft surfaces also
prevent proper ventilation.
❏ Good air circulation. Air must be able to move freely under
the system and behind it. Leave several inches of space
around the computer.
Moderate environmental conditions. Protect your computer
❏
from extremes in temperature, humidity, dust, and smoke.
Avoid direct sunlight or any other source of heat. High
humidity also hinders operation, so select a cool, dry area.
Appropriate power sources. To prevent static charges,
❏
connect all your equipment to three-prong, 120-volt
grounded outlets. You need one outlet for the computer, one
for the monitor, and additional outlets for a printer and any
other peripherals.
No electromagnetic interference. Locate your system away
❏
from any electrical device, such as a telephone, which
generates an electromagnetic field.
Setting Up Your System

Removing the Protector Card
2
If you have a 5¼-inch diskette drive, there is a protector card in
the diskette slot. This card is inserted at the factory to protect
the read/write heads in the drive. To remove it, flip the latch up
to pop the card out part way, then pull it out, as shown below.
(If you have a second 5¼-inch diskette drive, be sure to remove
the protector card from that drive as well.)
Save the protector card. If you transport your computer, you may
want to insert the card into your diskette drive prior to shipping.
This will protect the read/write heads during the shipping
process.
Setting Up Your System

Connecting a Monitor
3
The procedure you use to connect your monitor to the computer
depends on the type of monitor you have. If you have a VGA
monitor (or a multi-frequency monitor with an analog
connector), you can connect it to the computer’s built-in VGA
port. See “Using the VGA Interface” below. If you have any
other type of monitor, see “Using a Display Adapter Card”
below.
Using the VGA Interface
Follow these steps to connect your VGA monitor to the VGA
port on the computer:
1.
Make sure your monitor is turned off.
2.
Place your monitor on top of or near the computer. For easy
access, turn the monitor and computer around so the backs
of both components are facing you.
3.
If necessary, connect the monitor cable to the monitor.
(Your monitor may have a permanently attached cable.)
Setting Up Your System

4.
Examine the connector end of the monitor cable, and
position the plug to match the orientation of the monitor
interface (marked with a monitor icon). Then insert the
plug into the port (the connector should fit in easily when
properly oriented), as shown below.
To avoid damaging the connector, take care not to bend
the pins when inserting the plug.
5.
If the connector has retaining screws, tighten them by hand
or with a screwdriver, depending on the screw type.

Setting Up Your System
Using a Display Adapter Card
If you are using a non-VGA monitor, you’ll need to install a
display adapter (video) card in one of the computer’s option
slots before you can connect the monitor. (Your dealer may have
already installed the video card for you.)
If the video card has not yet been installed, you’ll need to follow
the step-by-step instructions in Chapter 5 to install an option
card. But first, check the following table to make sure your
display adapter card and monitor are properly matched.
When you are installing the video card, check to make sure any
switches or jumpers on the card are set properly. For example,
you may need to change a switch setting to select color or
monochrome. See the documentation that came with your
monitor or video card for instructions.
Setting Up Your System
1-7
Once you have installed your video card, return to this section
to connect your monitor to the computer. If your monitor came
with its own manual, follow the instructions there. Otherwise,
you can follow the steps in “Using the VGA Interface” above;
just insert your monitor connector into the video card port
instead of the built-in VGA port.
Connecting a Printer or Other Device
4
Your computer has both parallel and serial interfaces. To
connect a printer or other peripheral device to one of these
interfaces, follow the instructions below. Of course, Epson offers
a full range of printers; ask your dealer for more information.
Using the Parallel Interface
The parallel interface on your computer is Centronics®
compatible and uses a DB-25S connector.
To connect your printer and computer, you need an IBM
compatible printer cable. If you are not sure which one you
need, check with your Epson dealer.
1-8
Setting Up Your System
Once you have the correct printer cable, follow these steps:
1.
Place the printer next to the computer with the back panels
of both components facing you.
2.
One end of the printer cable has a 25pin, D-shell
connector. Position the plug to match the orientation of
the parallel interface (marked with a special icon). Then
insert the connector into the port, as shown below. If the
plug has retaining screws, tighten them by hand or with a
screwdriver, depending on the screw type.
Setting Up Your System
1-9
3.
Connect the other end of the cable to the printer, as shown
below. To secure the cable, squeeze the clips at each side of
the printer port and push them into place.
