to
one
of
three
types
of displays:
•
A
standard
color television set
•
A
composite
monitor,
such as
one
of
Radio Shack's
televisions
with
monitor inputs (16-250 or 16-232)
•
An
RGB
monitor
with
audio
capabilities—
Tandy's
CM-8
Analog
Monitor (26-3215)
is
strongly
recommended
for
the
best high-resolution
graphics
There
are
64
colors available
for
graphics
use.
The computer
also
generates musical tones
and
special
effects
through
the
speaker
in
your
TV
or monitor.
Keyboard
The
keyboard
consists
of
standard
typewriter
characters
plus several
control characters.
The
control
character keys are
marked
with
special
names
—
(break)
,
(enter)
,

,
£D,
and
so
on.

Microprocessor
This
is
the central
processing
unit
where
your
computer does
all its
"thinking."
Read
Only
Memory
(ROM)
ROM
is
where
the
computer
stores
built-in
programs,
including the
Color
Computer BASIC
language.
Each
time
you
turn
on
the
computer
without a
plug-in
program
cartridge,
this built-in
program
takes
charge
of
the microprocessor, enabling
you
to
type
in
simple
BASIC-language
instructions.
The
Color
Computer
3
with
Extended
BASIC
contains
a
32K ROM,
meaning
it
contains
32
x
1024
= 32768
characters
(bytes) of
permanently
programmed
memory.
