Technical information
PERIPHERALS
Mini Disk(s)
Connect one 26-1160 Mini Disk Drive and
up
to
three additional
26-1161 Mini Disk Drives,
as
explained in the Mini-Disk Operation
Manual. The connection cable is supplied with 26-1160.
Attach
one
of
the
flat connector hoods
to
the Mini-Disk connector
before attaching it
to
the Expansion Interface Card Edge. The ribbon
cable should exit from the
bottom
of
the
hood.
Bus Compatible Devices
This card-edge provides required signals for additional Radio Shack
peripherals. Any device
that
connects directly
to
the
TRS-80 can also
be connected here, with
the
exception
of
the
Screen Printer (Catalog
Number 26-1151). By using this Card-Edge,
you
don't
tie up
the
entire TRS-80 Interface with a single device.
For
example,
you
can connect the Radio Shack Voice Synthesizer
(Catalog Number 26-1180) to the Expansion Interface via this Card-
Edge.
Expansion Board
The Expansion Interface contains a special Expansion Board
Compartment
to
allow installation
of
another
optional printed
circuit board
to
expand
your
system's capabilities.
For
example,
you
can have the Radio Shack RS-232C Serial Interface
(Catalog Number 26-1145) installed in this compartment. This will
enable
your
TRS-80
to
communicate with
another
RS-232C device
(Telephone Interface, Serial Line Printer, etc.).
If
you
have enough experience in digital electronics,
you
might even
design
your
own circuit and install it in this compartment.
When
you
have such a board installed,
you
can access it via the
Expansion Board Card-Edge.
