Chapter 1

INSTALATION

IN

STALLA'HO~

The

Expansion

Chassis

is

easy

to

install,

but

take

care

to

install

it

correctly.

The

directions

for

installing

your

Expansion

Chassis

appear

in

this

chapter

as

step

by

step

instructions.

If

you

follow

all

the

directions

in

this

chapter

carefully,

you

should

have

no

trouble

installing

the

Chassis

.

If

you

are

familiar

with

the

installation

procedure,

you

may

want

to

refer

to

the

brief

installation

summary

in

Appendix C

instead

of

rereading

this

entire

chapter.

However,

if

this

is

your

first

time

installing

an

Expansion

Chassis,

read

this

chapter

thoroughly

and

carefully,

following

all

the

instructions

as

you

read.

What

You

Need

To

use

your

Expansion

Chassis

you

need

only

an

Apple

II

or

II

Plus

.

All

Mountain

Computer

peripherals

and

many

other

well

designed

peripheral

cards

will

work

in

the

Expansion

Chassis.

For

information

on

installation

considerations

and

limitations

for

the

Expansion

Chassis,

see

Appendix A

in

this

manual.

An

optional

item

you

may

find

useful

is

an

IC

puller,

a

small

tweezer-like

device

used

to

remove

IC's.

You

can

probably

get

one

at

your

local

computer

or

electronics

store.

You'll

find

that

installing

the

Expansion

Chassis

is a little

easier

if

you

have

an

IC

puller,

but

you

don't

have

to

have

one.

Unpacking

The

Expansion

Chassis

was packed

in a specially

designed

carton

to

insure

its

safety

during

shipping.

The

smaller

box

in

which

you found

this

manual

contains

items

necessary

for

installation

of

the

Expansion

Chassis.

The

Expansion

Chassis

itself

was

packed

beneath

the

smaller

box and

suspended

between

styrofoam

supports.

As

you

unpack

the

Expansion

Chassis

notice

how

it

was

packed,

and

save

the

packing

materials.

At

some

time

you

may

need

to

repack

your

Expansion

Chassis,

for

example,

if

you

wish

to

ship

it

for

servicing.

CHAPTER

1

INSTALLATION

Packing

List

As

you

unpack

your

Expansion

Chassis,

check

that

the

following

items

are

included:

•

Expansion

Chassis

A

smaller

box

containing

the

following:

•

Manual

•

Warranty

Card

•

Power

transformer

•

Expansion

Chassis

Interface

Card

•

Large

ribbon

cable

with

a 50

connector

on

each

end

•

Small

ribbon

cable

with

a 16

header

on

each

end

If

any

of

these

items

are

missing

from

your

package,

see

your

dealer.

NOTE

As

you

are

unpacking,

be

careful

not

to

drop

the

Expansion

Chassis

or

bump

it

against

a

hard

surface.

A

sharp

impact

can

damage

the

components

inside

the

Expansion

Chassis.

Before

Plugging

In

Before

you

begin

installing

the

Expansion

Chassis,

lay

all

the

necessary

items

within

easy

reach.

This

will

help

make

the

installation

procedure

go

smoothly

and

quickly.

In

addition,

make

sure

the

Apple's

power

is

turned

OFF.

This

is

important!

If

you

neglect

to

turn

the

power

off,

you

may

damage

the

Apple

and/or

the

Expansion

Chassis.

It's

a good

idea

to

familiarize

yourself

with

the

various

parts

of

the

Expansion

Chassis

before

you

actually

begin

installatiop.

Let's

take a look

at

these

parts

now.

The

Box

The

Expansion

Chassis

itself

is

housed

in a buff-colored

metal

box.

The

front

side

of

the

box

is

black

and

is

called

the

face

plate.

On

the

back

of

the

Expansion

Chassis

you

will

find

some

narrow

notches.

These

notches

will

allow

peripheral

card

cables

to

extend

from

the

chassis.

1-2

C

HAP'TEJi

~

JH3TAL

LATI

ON

As

you

face

the

front

of

the

Expansion

Chassis

you

will

see

on

the

right

edge

of

the

face

plate

two

LED

lights,

one

green

and

one

red,

and a square

shaped

black

button.

The

green

light

indicates

whether

the

Expansion

Chassis

is

powered

up,

and

the

red

light

indicates

whether

the

Expa

nsion

Chassis

is

selected.

The

button

is

used

to

select

and

deselect

the

Expansion

Chassis.

Remove

the

top

cover

of

the

Expansion

Chassis.

The

Expansion

Chassis'

cover

is

removed

in

much

the

same

way

as

the

Apple's.

Lift

the

back

edge

of

the

cover

at

the

middle

until

the

rear

fastener

pops

apart.

Then

slide

the

cover

backward

until

it

comes

free.

CAUTION

Make

sure

you

are

not

wearing

or

holding

any

metal,

such

as a ring

or a paper

clip,

on

your

hands

during

the

installation

procedure!

If

the

metal

touches

parts

of

the

power

supply

you

could

get a shock.

The

Mother Board

Because

the

Expansion

Chassis

is

now

empty,

you

have a perfect

opportunity

to

examine

the

mother

board

in

detail.

Following

is

a

labelled

diagram

of

the

Expansion

Chassis

mother

board.

CHAPTER

INSTALLATION

Notice

the

twin

cylinders

near

the

left

edge

of

the

Chassis.

These

are

capacitors.

Directly

to

the

left

of

the

cylinders

is

a

clear

glass

fuse.

In

front

and

to

the

right

of

the

cylinders

is

a

short,

round,

black

transformer

with

wires

extending

from

it

to

the

mother

board.

The

components

in

this

area

of

the

mother

board

comprise

the

power

supply.

Do

not

touch

anything

in

this

area

(unless

you

are

replacing

the

fuse)

even

when

the

power

is

off,

or

you

may

get

an

electrical

shock.

NOTE

If

the

Expansion

Chassis

power

supply

is

over-

loaded,

the

fuse

will

blow.

Replace

it

with

a

BUSS

MDX

1-1/2

amp.

fuse,

which

you

can

get

at

an

electronics,

hardware

or

autoparts

store.

Detailed

instructions

on

identifying

and

re-

placing

a blown

fuse

can be found

in

Appendix

B

--

Trouble

Shooting.

Along

the

back edge

of

the

Expansion

Chassis

are

eight

peripheral

card

slots,

numbered

from 0 to

7.

These

slots

behave

almost

exactly

like

peripheral

slots

in

the

Apple.

In

the

left

rear

corner

of

the

mother

board

is a 50

"male"

connector

labelled

"J1".

Notice

the

white

"1"

at

the

lower

right

edge

of

the

connector

and

the

"25"

at

its

upper

right

edge.

This

is

where

the

50

ribbon

cable

will

be

attached.

INSTALLATION

Interface

Card Jumper and

Switch

Positioning

The

following

paragraphs

describe

the

Expansion

Chassis

features

that

are

controlled

by

Jumper/Socket

sets

PP1

through

PP4

and

switch

pack

SW1.

PP1

Jumper/Socket

Set

PP1

(Figure

2)

allows

the

user

to

select

(or

deselect)

any

of

up

to

four

Expansion

Chassis,

via

soft-

ware.

It

selects

the

software

data

pattern

that

will

enable

the

Expansion

Chassis

associated

with

this

interface

card.

For

example,

if

the

jumper

is

placed

in

socket

FE

then

a

write

of

"FE"

to

location

C020-C02F

will

activate

the

Expan-

sion

Chassis

(writing

an

unused

pattern,

or a pattern

for

another

chassis

will

turn

this

chassis

off).

NOTE

Jumper/Socket

set

PP4

can

disable

this

software

select

feature.

The

setting

of

the

PP1

jumper

is

important

if

you

will

be

using

more

than

one

Expansion

Chassis

in a single

system.

PP2

CAUTION

Only

one

chassis

may

be

accessed

(via

software)

at a time.

If

two

Expansion

Chassis

have

the

PP1

jumper

in

the

same

socket

then

the

system

will

try

to

access

two

sets

of

peripherals

in

the

same

I/0

slots.

The PP2

Jumper/Socket

set

selects

whether

the

Apple

or

the

Expansion

Chassis

has

access

to

the

C800

through

CFFF

Apple

memory

locations.

The "A"

position

locks

the

C800

space

to

the

Apple.

The

"M"

position

dedicates

it

to

the

Expansion

Chassis.

The

"P"

position

allows

the

c8oo

space

to

be

used

by

the

software

selected

user.

PP3

The

PP3

Jumper/Socket

set

determines

whether

the

Apple

or

the

Expansion

Chassis

will

be

selected

after

the

Apple

RESET

key

has

been

pressed.

The "P"

position

allows

the

Apple

to

be

selected

during

power-up

only,

the

Expansion

Chassis

will

be

selected

if

the

RESET

key

is

pressed.

The "R"

jumper

position

selects

the

Apple

for

power-up and
