INSTALLING
THE
CTD
To
attach
the
CTD
to
your
sy
stem, follow
the
appropriate
set
of instructions
listed
below. Before installing
the
drive, check the revision and
mod
level
of
the
64FDC
board
(the
revision
letter
is etched into
the
solder side of the board,
and
the
mod
level
number
is
indicated
by
a
label,
also
on
the
solder side).
If
you
do
not have aRevision Dboard with
mod
level 7or higher, then
the
64FDC
must
be
modified (refer
to
the
last
section of this
chapter,
"Using the
64FOC
with the CTD").
System One and System
100
Adding aCTD
to
model
CS1
(two 5-1/4" floppy drives) precludes
the
addition
of another floppy disk drive. However, model
CS1H
and System 100 (one 5-1/4"
floppy drive and one hard disk drive) can
support
both a
CTD
and another floppy
disk,
in
which
case
the
second floppy disk becomes Drive
B,
and plugs
into
the
back of the CTD connector.
Install
the
CTD
as
follows:
1.
Turn off
the
system, and remove
the
upper and lower
rear
panelsas
described in your system manual.
2.
secure
the
drive cable
adaptor
(figure
1-2)
to
the
new connector panel
(part
number 016-0330),
as
shown in figure 1-3.
If
you
-have
aSystem 100,
which has
the
new panel already
installed,
unscrew
the
cover from
the
drive connector
slot,
attach
the
adaptor,
and go
to
step
4.
3. Disconnect
all
cables from
the
rear
panel.
Unscrew the connectors from
the old
rear
panel and
secure
them
to
the new one.
4. Plug one end of
the
50-conductor
cable
(part
number 519-0209) into J 3
on the
64FDC
board, and plug
the
other
end
into
J3
on
the
drive cable
adaptor.
The red cable
stripe
should
be
to
the
right
as you
face
the
back
of
the
sy
stem.
5. Replace
the
rear
panels
and reconnect
all
cables.
Plug
the
CTD
cable
into
