The

HD-20

is

designed

to

operate

in

aCromemco

System

Two

or

Three.

Prior

to

installation,

verify

that

the

drive

is

set

up

to

respond

as

Signal

Cable

Connection

The

36

conductor

signal

cable

is

connected

between

the

HD-20

and

the

WDI-II.

The

first

step

in

the

installation

of

the

HD-20

is

the

co

nnecti

on

of

the

signal

cable

to

the

HD-20.

This

must

be

done

before

the

drive

is

mounted

in

the

system.

Looking

at

the

rear

of

the

drive

with

the

heat

sink

on

the

left,

the

cable

is

connected

with

the

index

strip

to

the

right.

See

Figure

You

are

now

ready

to

mount

Mounting

Procedure

The

HD-20

mounts

just

below

the

two

5"

floppy

disk

drives

in

the

System

Two.

Each

of

the

two

flopPY

disk

drives

is

held

in

its

metal

frame

by

means

of

6-32

screws.

Remove

th€!

two

bottom

retaining

screws

from

each

drive

and

then

reinstall

them

so

that

the

mounting

plate

for

the

HD-20

is

attached

to

the

bottom

of

the

two

floppy

disk

support

housings.

Refer

to

Figure

Plug

the

HD-20

power

cord

into

the

plug

on

the

HD-20.

This

connector

is

designed

so

that

it

can

only

be

connected

one

way.

Now

slide

the

HD-20

onto

the

HD-20

mounting

plate.

Refer

to

Mounting

Procedure

The

HD-20

mounts

in

the

area

where

the

C

and

D

disk

drive

is

normally

located.

The

HD-20

cannot

be

installed

in

a

system

with

two

disk

drives

(four

slots

-

A, B, C,

and

D).

To

mount

the

drive

and

power

cable

it

is

necessary

to

remove

the

top

cover

and

the

rear

panel

from

the

System

Three.

Orient

the

HD-20

with

the

power

supply

cooling

fin

up

and

the

rear

of

the

drive

(part

where

the

signal

cable

is

connected)

facing

you.

See

Figure

5.

With

the

signal

cable

routed

along

the

right

side

of

the

drive,

slide

the

drive

into

the

mounting

area

far

enough

so

that

the

HD-20

power

plug

can

be

connected

through

the

top

opening

in

the

mounting

frame.

NOW,

slide

the

HO-20

forward

until

it

is

approximately

1

1/4"

from

the

front

of

the

mounting

frame

and

attach

the

drive

at

that

point

by

means

of

two

screws

as

shown

in

Figure

5.

The

signal

cable

should

be

routed

to

the

card

cage

following

the

same

path

used

by

the

floppy
