INSTRUCTION

Thank you

for

purchasing the SHARP Floppy Disk MZ-80SFD.

It

is

a peripheral

unit

for

use

with

the SHARP Personal Computer which

can

operate a maximum

of

4 drives.

We

believe

that

it

will

be

very useful

as

an

external memory

unit

because

of

its large capacity and high

speed

access.

Read

this instruction manual carefully before using the

Floppy

Disk

so

you

can

use

it

correctly.

Precautions

• Terminal resistor

Which drive must

or

must

not

be

fitted

with

a terminal resistor

is

dependent on

the

combina-

tion

or

number

of

drives

to

be

used.

For

prevention

of

troubles, every drive

leaves

our

plant

with

any terminal resistor

not

attached. When

mounting

a terminal resistor,

read

the directions given

later carefully and attach the resistor

to

a right drive. Improper attachment could

cause

damages

to

connected drives.

• Upgrading

the

drive system

A

maximum

of

four

MZ-80SFDs

can

be

used

in daisy-chain connection

or

the MZ-80FB

or

MZ-80FB

K-

an

extension drive

unit

for

the

MZ-80FB-

can

be

used

in

conjunction

with

one

or

two

MZ-80SFDs

to

upgrade the drive system. When upgrading the drive system, interconnect

necessary drives in the specified manners shown later. Incorrect interconnection

will

destroy the

drive signal

circuit.

• Connection

with

the

computer

system

When connecting any drives

to

the

computer

system,

be

sure

to

switch

off

the whole system in

advance.

• Power supply

Be

sure

to

use

a supply voltage

that

is

shown on the rating plate attached

to

the back

of

the

MZ-80SFD. The

use

of

any

other

supply voltage

causes

damages

to

the drive. Also, never connect

the MZ-80SFD

to

the

same

electrical

outlet

where some apparatus

that

generates a noise - a

heavy-duty

motor,

etc. -

is

connected, otherwise the system could

malfunction.

•

Humidity

and

dust

The MZ-80SFD, a precIsion engineered gadget, dislikes

an

excessive

humidity.

Avoid using this

drive in a location

that

is

subject

to

high

humidity

or

exposed

to

much dust.

(Ambient

humidity

=20

to

80%)

• Installation requirements and impact

The MZ-80SFD

is

composed

of

precision engineered mechanisms and electronical components.

Use

it

in a location

that

is

not

subject

to

an

extreme high

or

low

temperature,

abrupt

temperature

changes,

or

heavy vibration

or

exposed

to

much dust. Never give any unreasonable impact

to

this

device

by

putting

something on

it

or

dropping

it

by

mistake. Also, never place

it

near a speaker,

TV

set,

or

tape recorder because these are generating magnetism. This

will

cause

malfunction

ef

the drive

or

delete data

or

texts stored in a diskette.

Never operate the MZ-80SFD slanted. This

will

impede correct

writing

or

reading.

Also, place the signal cables

of

the system kept

as

far away

as

possible

from

the

other

associate

devices and the power cords.

• Power cord

Be

careful

not

to

place a desk

or

chair on the power cord

or

catch

it

in anything, otherwise the

cord could

be

damaged. The

use

of

a damaged power cord

leads

to

hazard. When disconnecting the

power cord,

be

sure

to

pull

it

off

by

holding the plug.

• When the MZ-80SFD

is

expected

not

to

be operated over

an

extended period

of

time

Be

sure

to

disconnect

the

power cord

from

the electrical

outlet.

• Stain

If

the machine

is

contaminated, gently wipe

it

with

soft

cloth

soaked in water

or

cleaning

fluid.

Neither

use

any volatile chemicals such

as

benzine and

thinner

nor spread insecticide on the

machine. This

will

result in discoloration

of

the cabinet.

• Terminal resistor

The drive system requires

to

have

one

of

its component drives provided

with

a terminal resistor.

It

must

be

noted, however,

that

which drive should

be

provided

with

a terminal resistor depends

upon the number

of

connected drives. In principle, the drive remotest

from

the interface alone

needs a terminal resistor.

If

the drive system contains

two

or

more drives

with

a terminal resistor,

those drives get damaged when the system

is

put

in operation.

Pay

due

attention

to

this regard.

When attaching a terminal resistor,

follow

the procedure given below.

(1) Unscrew the panel under the indication

"TERMINAL

RESISTOR" which

is

secured

with

two

screws.

You

will

find

a socket then.

(2)

Mount

a supplied terminal resistor on the socket. This resistor, having no

polarity,

can

be

mounted in any orientation.

(3) Make sure the resistor

has

correctly

been mounted, then replace and screw the panel.

(1) Signal cable

The signal cable

to

interconnect individual drives and the one

to

interconnect a drive and the

interface card are

different

in length.

(a)

Interconnection

of

drives (or

their

terminals

"IN"

and

"OUT")

For

this purpose

use

signal cable

MZ-80FCK

(option).

(b) Interconnection

of

a drive and the interface card (or the terminal

"IN"

of

the drive and the

terminal

of

the card)

For this purpose

use

signal cable MZ-80FC (option).

The overall length

of

the cables

used

between the interface card and the drive

with

a terminal

resistor

is

limited

to

3 meters

or

less.

If

the length

is

longer than 3 meters, the drive system

may

malfunction.

(2) Signal cable connection

Connect a signal cable connector

to

the terminal

"I

N"

or

"OUT"

on the back

of

each

drive

or

to

the interface card terminal, then secure

both

ends

of

the connector

with

two

pieces

of

supplied screws.

1 Diskette

This

unit

uses

a

5.25"

mini-disk

that

records on

both

sides

as

the

recording medium. Its external appearance

is

as

shown on the left.

It's

called a diskette and

is

a magnetic

sheet covered

by

a jacket.

2 Inserting a Diskette

1. Put a finger on the

bottom

of

the

front

door

and

lightly

put

this

door

toward you

to

open

it.

2.

With

the

label side up and

the

head

window

forward,

insert a diskette in the slot. There

is

no other way

to

insert a diskette correctly.

3.

Push

the diskette

lightly

until

it

stops and close the

front

door.

If

the diskette

is

not

inserted all the way,

the

front

door

wi

II

not

close. When this happens do

not

force the

door

closed

but

re-insert the diskette correctly.

3 Write-protection Notch

If

the write-protection notch

of

the diskette

is

covered

with

a

seal

of

silver paper, etc.,

writing

of

data

is

forbidden. Reading, however,

is

possible. Some diskettes

supplied

by

Sharp

that

are

called Masters

have

this part

covered

with

a

seal.

Never remove

it

because

it

prevents

trouble

from

improper operation.

Do

not

cover the notch

of

a diskette

that

is

ordinarily

used

for

read/write operations

with

a

seal,

etc. or

writing

will

be

impossib

le.

4 Data Read/Write

Operation

of

this

unit

is

only

by

ON/OFF

of

the power

and insertion/removal

of

a diskette.

All

reading

and

writing

of

data

is

controlled

by

the host computer. For

details refer

to

the software manual. A maximum

of

4

drives

can

be

operated and drives

are

designated

by

the

drive numbers on the

front

of

the

unit.

8

~

Envelope

Do

not

touch, soil

or

scratch the recording surface (Head

Window)

of

the diskette

with

your

finger. This may

cause

improper

operation

or

result in no operation.

Do

not

bend

or

fold

the diskette

or

it

will

become unusable.

Do

not

bring magnetic things near the diskette

or

the

contents

of

the diskette

will

be

destroyed. In

addition,

it's

dangerous

to

bring a diskette near machines (motors, etc.)

that

generate a magnetic field.

Fill in the index label before pasting

it

on the jacket

or

use

a

soft

pointed pen.

If

you

use

a ball-point

pen

or

other

hard

object on a label already pasted on the jacket, the diskette

will

be

damaged.

When

not

using a diskette,

put

it

in

an

envelope and file

it

away. This also prevents

trouble

caused

by

scratches and

dust.

Storage temperatures

for

the diskette are

4°(

to

53°(.

Do

not

leave

the diskette exposed

to

direct

sunlight,

or

locate

it

in a place subject

to

the temperatures exceeding

53°(.

This

may

cause

the jacket

to

be

deformed and unusable.

When using the diskette, ensure

that

the temperature range

described on the protective envelope

is

observed. Environ-

mental conditions may

differ

between the storage and opera-

tion

places. This requires the diskette

to

be

placed under the

proper operating environment

for

a

while

before

use.
