CPU

SPEED switch

There are no DIP switches on the Equity Ile. However,

there is a CPU SPEED switch on the front of the unit in

the lower left hand comer.

The CPU SPEED switch selects between 8MHz and

12MHz. When the computer is running at 8MHz, the

power light is orange, and at 12MHz, the light is green.

Installation / Support Tips

Power

The Equity

has

a power supply that is switchable between

115 V, for USA and Canadian use, and

23fIV,

for

use

in other

countries. The

voftage

switch is located at the rear of the CPU

between the AC inlet and the AC outlet. (see figure below)

WARNINGI

The voltage is not changed between the

AC inlet and the AC

outlet.

the CPU is switched for

230 V in order to

function

in Europe, only peripherals

certified for use at 230 V should be plugged into the

outlet.

Installing Floppy Disk Drives

When installing a floppy disk drive as drive B,

remember to set the drive select jumper to the

second position and attach the pass-through

connector on the floppy drive controller cable to the

drive, not the end connector.

Equity Series Computers

the

drive

doea

not function normally, make sure

that the drive type

haa

been correctly seNcted In

SETUP.

Aleo

check that any

apeolal

drivers that

may

have been

tnsta5ed

correotly.

Installing Hard Disk Drives

reoommended

that a W-bit AT-type hard

disk

controller be used in the Equity IN, if you are

installing a drive that cannot make use of the

internal HI board.

AJso

remember to disable the Hi

board when Installing such a

drfve.

you are having difficulty In formatting the hard

d&k drive, try starting over

wfth

the Unconditional

Format option in diagnostics.

Setup

When installing an optional expanded memory

board, do not list the memory under the memory

expansion option in SETUP. That

optfon

is for

EXTENDED memory ONLY.

When installing a hard disk

drfve,

be sure to

cons&

the

drive

type

tables (on page

EOlfe-4)

for the drive

type which

ffts

the drive you are installing.

Adding Memory Modules

The

total amount of memory must be one of the

following: 1 MB,

2MB,

3MB

5MB.

Memory banks must be filled with one size SIMM.

You cannot mix SIMM types in one bank.

Software Problems

When installing a copy-protected software package

on the Equity lie, first try the installation at 12 MHz.

this does not work properly, try switching to

8 MHz for the installation.

you are still unable to

load the program at 12 MHz, try loading at 8MHz

and then switching to 12 MHz.

When using a software pa&age that uses a

keydlsk

as it copy-protection method, try loading it at 12

MHz. lf this does not work, enable the Auto Speed

option in SETUP.

EQUITY lIe

Power-on Password

Make sure that you do not forget the Power-on

Password should you set one up.

you do, it will

nW%ssary

to disable it by moving jumper 1 on

the main circuit board to the B position.

EQlle-6

you enable network server mode after

instelling

password, the computer prompts you for that

password before allowing you to

aax

the system

as long as you boot the system from the

Fleferenos

diskette.

However,

if you install MSDOS on the hard disk

and buot from that

d&e,

the prompt no longer

appears. The computer shows the normal MS-DOS

prompt (e.g.,

C>),

but it still requires the password

before allowing you to access the system in

network server mode.
