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

The $80

is
set

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).

The
reason
for

I.
To
replace
the

renove
the

as
shown
in

motor
stops
rotating
approximately
15
seconds
after
