To Our
Customers . .
.
The TRS-80® X-Pad (Model GT-116)
is
a
revolutionary
way
to take advantage of
the
high-resolution graphic
capabilities of your TRS-80 Color
Computer.
With a
minimum
of
programming, the
X-Pad lets you
plot
graphics that
are
displayed
on your Color
Computer's
TV
Screen.
Furthermore,
all
graphic
displays can be saved
on
cassette
tape
for later
use
or printed on
a
graphics printer
for "hard-copy" output.
The X-Pad
will
open
an entire
world
of
graphic
applications
for
you
—
mapping,
graphic
displays,
statistics, waveform analysis,
marketing
analysis, and
charting,
to
name just
a
few. Besides that,
it's
fun!
To use X-Pad,
you'll need
a:
•
16K
or 32K Color Computer
with Extended
Color
BASIC.
•
Color TV.
And while not required, it is extremely
convenient
to
save
your programs on cassette; we suggest
the
CTR-80A
Cassette
Recorder
(Radio
Shack Catalog Number
26-1206).
