Recorder Cable (DIN plug on one end and three
plugs on the other) to the Tape I/O connector that is located on the
rear of the Expansion Interface nearest the Power Cord exits. (Refer
to Figure 5).

Of the three plugs on the other end of the Cable:

1. Connect the black plug to the EAR jack on the side of the
Cassette Recorder.

2. Connect the larger gray plug to the AUX jack.

3. Connect the smaller gray plug to the REM jack.

=NOTE=

A Dummy Plug is provided with your Cassette Recorder. Plug it
in to the MIC jack. This Plug disconnects the built-in
microphone so it won't pick up sounds while you are loading
tapes.

Connect the Cassette Recorder Jumper Cable to the center DIN connector
on the rear of the Expansion Interface. Connect the other end to the
TAPE connector on the right rear of the TRS-80.

Connect the Video Cable from the Video Display to the VIDEO connector
on the right rear of the TRS-80.

=NOTE=

Your Cassette Recorders may be powered by batteries or from a
120 VAC source. Thus, AC power cords are optional.

The TRS-80 Expansion Interface has been designed to support the Video
Display module. Set the feet of the Video Display in the recesses in
the Power Supply and PCB Housing Doors. (Refer to Figure 6).

OPERATION

=NOTE=

The Power switch is recessed into the front of the Expansion
Interface to prevent accidental loss of power. Activate the
switch with the eraser-end of a pencil or small tool of
similar size.

Apply power to the Expansion Interface. Notice that when power is off,
the end surface of the switch is white and when power is on, it
changes to orange.
