1.1

GENERAL

The

IOO

54

controller

is

a

disk

controller

that

is

used

with

the

10

..

5"

Fujitsu

Eagle

(470

MB).

The

IOO

32/42/52

controllers

ensure

data

integrity

by

verifying

each

sector

imnediately

after

each

write

operation.

The

IOO

54

controller

offers

an

alternative

approach:

each

sector

may

be

written

without

verification

with

the

expectation

that

infrequent

read/write

errors

will

be

recnvered

when

the

sector

is

read

using

the

error

correction

process.

This

option

has

not

yet

been

implemented, however

it

may

be

available

in

the

near

future.

As

the

error

correction

process

is

capable

of

recovering

a

small

error

(a

single

"burst-'

of

up

to

11

consecutive

bits),

and

rot

a

large

error,

all

sectors

with

media

defects

must

be

alternated

prior

to

using

the

disk.

If

this

procedure

is

rot

followed

data

will

be

lost

inmediately

on

uncorrectable

sectors

and

sanewhat

later

on

sectors

that

become

uncorrectable

through

time.

The

disk

must

also

be

periodically

analyzed

in

order

to

detect

and

alternate

marginal

sectors.

There

will

be

a

magnetic

tape

with

each

Fujitsu

Eagle

Disk

that

will

have a

canplete

list

of

defects

on

that

particular

unit.

'!he

ATP

MISC54

will

have a

formatter

that

will

read

in

the

tape,

and

will

automatically

generate

an

al

ternate

sector

for

each

defective

sector.

SWITCH

SEI'I'!NG3

The

controller

is

usually

set

to

address

"D",

but

can

be

set

to

any

address

that

is

not

being

used

by

another

device.

The

setting

of

the

configuration

switches

depends

upon

the

disk

drive

being

used

at"1d

whether

the

verirj-after-write

check

is

enabled.

Use

the

following

table

to

set

the

configuration

switches:

Fujitsu

Eagle

470

$96

or

$16

The $80

switch

is

set

to

if

the

Until

notice,

all

2.2

CABLING

The 100 54

is

connected

to

the

disk

drive

by

two

ribbon

cables.

The

radial

cable,

which

is

connected

to

P3

on

the

1aJ

54

has

26

conductors.

The

buss

cable,

which

is

connected

to

P4

on

the

100

54

has

60

conductors.

The

red

stripe

must

face

up whenever a

cable

is

connected

to

the

100

54.

The

red

stripe

must

also

correspond

to

pin

1

on

the

disk

drives'

interface

connector

(pin

1

is

often

marked

by

an

arrowhead

on

the

interface

connector

I

or

a

pin

nunber

near

the

connector).
