THETHREE
OPERATING
MODES
OF
THE
COMMODORE
128D
The
Commodore
128D
is
actually
three
computers
in
one,
offering
three
primary
operating
modes:
•
C128
Mode
•
C64
Mode
•
CP/M
Mode
Here's
a
summary
of
what each
mode
gives
you.
C128DMode
In
C128™
Mode,
the
Commodore
128
Personal
Computer
provides
128K
of
RAM
(Random
Access
Memory).
This
supplies
all
the
mem
ory
needed
to
run
even
sophisticated
applications
like
word
process
ing,
spreadsheets,
database
programs,
or
integrated
software
pro
grams
like
JANE.
And
you
can
easily
expand
the
RAM
to
256K
or
640K
with
optional
RAM
expansion
modules.
C128
Mode
also
incorporates
a
powerful
extended
Commodore
BASIC
language,
known
as
BASIC
7.0.
Offering
over
140
commands,
statements
and
functions,
BASIC
7.0
provides
better,
quicker
and
easier
ways
to
perform
what
otherwise
would
be
complex
and
time-
consuming
programming
tasks,
such
as
graphics,
animation,
sound
and
music.
C128
mode
also
offers
both
40-
and
80-column
output,
and
a
92-key
keyboard.
The
keyboard
features
a
numeric
keypad
as
well
as
Escape,
Tab,
ALPHA
Lock,
and
Help
keys.
The
powerful
capabilities
available
in
C128
mode
are
complemented
by
the
family
of
new
peripheral
devices
from
Commodore
(1571
fast
disk
drive,
1902
40/80-column
RGBI
monitor,
etc.).
And
you
can
still
use
all
standard
Commodore
peripherals
as
well.
lnC64
Mode,
the
Commodore
128
retains
all
the
capabilities
of
the
commercially
successful
Commodore
64,
thus
allowing
you
to
take
full
advantage
of
the
wide
range
of
available
Commodore
64
soft
ware.
You
also
have
full
compatibility
with
standard
Commodore
64
peripherals,
including
user
port
and
serial
devices,
cassette
recorder,
joysticks,
composite
video
monitors,
and
TV
output.
C64
Mode
provides
the
BASIC
2.0
language,
40-
column
output
and
access
to
64K
of
RAM.
The
keyboard
provides
the
same
functions
available
on
a
Commodore
64
computer.
And
all
the
Commodore
64
graphics,
color
and
sound
capabilities
are
retained,
used
exactly
as
on
a
Commodore
64
computer.
