Product

Description

The

JEI049

is

designed

to

control

up

to

four

floppy

disk

drives

(360K,720K,

1.2M

and

1.44M types).

They

can

all

be

mounted

internally,

or

two

internal

and

two external.

There

are

two

cables

that

are

used

to

connect

the

JE

1049

to

the

floppy

disk

drives.

There

is

a

34-pin

cable

which

carries

the

controlsij!nals

to

the

floppy

disk

drive

and

returns

status

signals

back

to

the

JEI049.

The

cable

also

carries

data

between

the

floppy

disk

drive

and

the

computer.

If

you

will

be

you

will

an

additional

cable.

Terminology

Throughout

this

manual,

a variety

of

common

computer

terms

and

abbreviations

will

be

used.

For

your

convenience, a glossary

of

standard

computer

terms

has

been

included

at

the

end

of

this

manual.

1.5

Precautions

When

working

with

any

circuit

board

or

IC,

some

precautions

need

to

be

observed

for

the

safest

installation. Many

parts

are

static

sensitive

and

may

be

easily

damaged

by

static

electricity

that

may

have

built

up

in

your

body. The

best

way

to

assure

that

no

damage

comes

to

your

new

equipment

is

to

observe a few

precautions:

1.

Whenever

you

move

your

body,

you

can

easily

build

up

enough

static

electricity

to

damage

a

board.

When

handling

a

board

or

chips,

ground

yourself

often.

The

best

way

to

do

this

is

with

a

grounding

wrist

strap

that

is

properly

connected

to

a frame

ground.

These

may

be

purchased

through

Jameco

Electronics

(Part # WS).

Another

method

to

ground

yourself

would

be

to

plug

the

computer's

power

supply

into

a

grounded

outlet

(but

leave

it

turned

om,

then

touch

the

frame

of

the

power

supply

often

to

dissipate

any

static

charge

that

you

may

have

built

up.

2. Make

sure

that

the

power

supply

is

turned

OFF before

installing

or

removing

anything.

3. Hold all

boards

by

the

edges.

go

to

section

2.4.5.

1.

Remove

the

screw

that

the

old floppy

disk

drive

controller

is

held

in

with. Save

this

screw

since

it

will

be

used

later

to

secure

the

in

place.

2. Disconnect

the

it

is

connected

to.

3. Remove

the

the

slot it

is

in.

2.4.5

The

should

have come with

its

cable already

connected

to

it.

Take

a look

at

the

cable

and

refer

toF4!ure

will

notice a

red

OPERATION

3.1

Disk

Operating

Systems

In

order

to

use

your

JE

1049

you

will

need

a DOS (Disk

Operating

System).

This

is

software

that

you

can

buy

from

most

software

mail

order

houses

and

software'

stores.

The

two

most

common

types

are

MS-DOS

and

PC-DOS.

In

most

cases,

both

should

work

fine

with

the

JE

1049.

PC-DOS

is

the

operating

system

that

is

available for

the

PC,

XT

and

AT

computers

made

by

IBM

and

is

sold

under

the

IBM

name.

MS-DOS

is

written

for

the

IBM

PC

series

of

compatibles

on

the

market

(i.e. Compaq, Leading Edge, etc.).

Each

of

these

types

of

DOS, PC-DOS

and

MS-DOS, have

come

in

numerous

versions

(e.g.

2.1,

3.0,

3.3,

etc.).

If

you

plan

to

use

a

720K

3.5

inch

floppy drive

you

will

need

version

3.2

or

higher. If

you

plan

to

use

a 1.44M

3.5

inch

floppy drive

you

will

need

version

3.3

or

higher.
