of the Z-80.
You
can
access the Z-80's
numeric "machine
language"
directly
by using
our
"T-Bug"
monitor
program,
availabie
on
cassette
tape,
or
in "assemlcly
language"
by using
our
"Editor/Assembler"
tape.
(Both

tapes
are suggested
only for
advanped

with
a knowledge
of machine
and assembly
language.)
The
Realistic cassette
recorder
lets
you
record
and
play
your
own
programs
or use
one of
Radio Shack's
prepared pro-
grams
-
simply
run the
cassette
and begin
computing.
Other re-
corders
may
be used-with vary-
ing
degrees of success-but
only
if
they have
automatic
recording level
capability.
The video monitor
looks
like a
standard television
set without
the
channel selector.
It features
a
wider
bandwidth
than most
TV
sets for
a sharper display
ofprint-
ing
and
graphics.
The monitor
operates
on ordinary
120-volt
AC,
60 Hz house
current. Foreign
versions
are
available in
other
countries
and are
sold only over-
seas
by
Tandy
Electronics
out-
lets. The computer
cannot
be
connected
directly
to a standard
TV set.
For
access
to other hardware,
the
TRS-80
utilizes a
unique
40-pin
bus
(connector
system)
that can
attach the
TRS-80 to our
Expansion
Interface,
or other ex-
temai devices.
Housed in
the finest ABS@
mate-
rial, the
TRS-80 is
virtually un-
breakable.
It may
be left
"on"
for
extended
pedods
of time with no
adverse effects,
as long
as the
cooling vents
are not
obstructed.
