Radio Shack TRS-80 Trsdos & Disk Basic Reference Manual

Mini
Disk
Operation
Connections
The
power to
all
components
in the TRS-80
system
should
be "off
while
you
make
connections.
Look at the ribbon-type
connector
cable
included
with your
26-1
160
Mini
Disk drive.
Notice
that
the cable
has
four
edge card
connectors
through
its
length,
and a
single
connector
at the
other
end. Connect
the single
plug
to
the
edge-card
jack on the left rear
of
the
Expansion Interface,
as
shown
in Figure
3.
Be
sure the plug
is
oriented
so
the cable exits from
the bottom.
Before connecting
the Drive(s)
to the
cable, note the
following rules:
1)
26-1
160
must
always be
the
"terminal" or final
drive on the
cable;
that is, of all
your
drives,
it must always
be the farthest
away
from the Expansion
Interface.
This is
because it includes
the
terminating
resistors
mentioned above.
2)
The
connector
closest
to
the
Expansion
Interface
must
always
be plugged
in
to a drive.
The
other
connectors
can
be
"empty".
