Built-in
MSX-BASIC
The
built-in
MSX-BASIC
has
various
commands,
statements
and
functions
which
allow
you
easy

development.
With
the
MSX-
BASIC
sprite
function,
you
can
make
and
move
the
different
patterns
on
each
of
the
32
sprite
planes.
The
sound
generator
makes
it
possible
to
output
three
tones
and
one
noise
simultaneously,
so
that
you
can
generate
various
effect
sound
or
music
by
using
the
PLAY
and
SOUND
statement
of
the
MSX-BASIC.
Two
supplied
manuals
for
the
MSX-BASIC
will
tell
you
not
only
how
to
use
the
MSX-BASIC
but
also
the
pleasure
of
programming.
Easy-to-use

The
Personal
Data
Bank,
which
is
the
supplied

220V
ac.
•
Should
any
solid
object
or
liquid
fall
into
the
cabinet,
turn
the
power
off
and
have
the
unit
checked
by
qualified
personnel
before
operat¬
ing
it
any
further.
•
Unplug
the
unit
from
the
wall
outlet
if
it
is
not
to
be
used
for
an
extended
period
of
time.
•
Do
not
place
or
drop
heavy
objects
on
the
power
cord.
Use
of
a
damaged
cord
is
dangerous.
To
disconnect
the
cord,
pull
it
out
by
the
plug—never
pull
the
cord
itself.
On
installation
•
The
computer
consists
of
high-precision
electronic
parts.
Do
not
drop
it
or
bump
it
against
other
objects.
Do
not
place
it
in
a
place
subject
to
vibration
or
on
an
unstable
base.
•
Do
not
install
the
unit
near
heat
sources
such
as
a
radiator
or
an
air
•
duct,
or
in
a
place
subject
to
direct
sunlight,
excessive
dust,
and/or
moisture.
•
Do
not
place
electronic
equipment
near
the
computer.
It
may
mal¬
function
if
affected
by
an
electromagnetic
field.
•
Provide
adequate
air
circulation
to
prevent
internal
heat
build-up.
Do
not
place
the
unit
on
surfaces
(rugs,
blankets)
or
near
materials
(curtains,
draperies)
that
may
block
the
ventilation
slots.
•
Use
only
the
specified
peripheral
equipment;
otherwise,
trouble
may
result.
Before
connecting
peripheral
equipment,
be
sure
to
turn
the
power
off
or
the
internal
1C
chip
may
be
damaged.
•
Keep
the
supplied
personal
data
bank
away
from
equipments
with
magnets,
such
as
speakers
and
amplifiers,
because
their
magnets
could
cause
erasures
of
the
personal
data
bank.
On
cleaning
•
Clean
the
cabinet
and
keyboard
with
a
soft,
dry
cloth,

HB-501P
HOW
TO
STARTUP
The
computer
itself
consists
of
many
electronic
parts
such
as
LSIs
and
ICs,
and
other
electrical
and
mechanical
parts.
These
are
called
“hardware”.
The
computer
can
perform
various
kinds
of
jobs
using
programs
that
determine
the
sequence
the
computer
should
follow
to
do
the
job.
(These
programs
are
also
called
“software”.)
For
the
HB-501P,
there
are
mainly
four
types
of
program:
•
Program
built
in
the
HB-501P
Personal
Data
Bank
MSX-BASIC
interpreter
•
Program
stored
in
the
cassette
supplied
with
the
HB-501P
Personal
data
bank
•
Commercially
available
programs
in
MSX-cartridge
form
Games
and
other
useful
programs
are
available.
•
User
designed
programs
in
MSX-BASIC
You
can
make
your
own
programs
using
the
built-in
MSX-BASIC
interpreter.
A
knowledge
of
BASIC
programming
is
required.
When
all
the
necessary
connections
have
been
made,
select
the
program
and
follow
the
appropriate
steps
to
get
started.
TO
START
UP
THE
PERSONAL
DATA
BANK
Insert
the
supplied
cassette
tape
into
the
bit-corder
and
make
necessary
adjustments
for
loading.
For
details,
refer
to
“How
to
use
the
Personal
Data
Bank”.
Data
created
by
the
Personal
Data
Bank
can
be
saved
to
a
cassette
using
the
built-in
bit-corder,
to
an
optional
HBI-55
data
cartridge
or
to
a
microfloppy
disk
using
the
HBD-50
micro
floppydisk
unit.
To
use
the
data
cartridge
or
micro
floppydisk
unit,
first
insert
the
data
cartridge
or
the
interface
cartridge
of
the
micro
floppydisk
unit
into
the
cartridge
slot
LU
or
[
2
],
then
turn
on
the
power.
Refer
to
“How
to
use
the
Personal
Data
Bank”
for
details.
Note
on
MSX-DOS
When
MSX-DOS
commands
(except
DIR,
FORMAT
and
BASIC)
are
used,
data
created
by
the
Personal
Data
Bank
are
not
maintained.
Therefore,
be
sure
to
save
data
before
transferring
control
from
the
Personal
Data
Bank
to
MSX-DOS.
Once
the
above
MSX-DOS
commands
are
used,
the
following
MSX-
BASIC
commands
cannot
be
used:
SAVE
“CAT:”,
LOAD
“CAT:”,
CALL
HITBIT

HOW
TO
USE
THE
BUILT-IN
BIT-CORDER
There
is
no
need
for
troublesome
connection
between
the
recorder
and
computer
with
the
built-in
bit-corder.
Saving
and
loading
of
various
MSX
Basic
programs,
data
files
and
Personal
Data
Bank
data
can
be
made
on
a
single
cassette
tape.
Each
program
or
data
file
can
be
easily
found
afterwards
by
inserting
a
blank
of
more
than
4
seconds
between
each
program
or
data
file.
CASSETTE

take
up
any
slack
in
the
tape
to
prevent
it
from
becoming
tangled
around
the
capstan.
3
C

A
PROGRAM
CAUTION
When

counter.
TO
VERIFY
A
PROGRAM
It
is
important
to
verify
the

immediately
after
it
has
been
saved.
The

Cassette
care
•
Avoid
touching
the
tape
surface
of
a
cassette,
as
any
dirt
or
dust
will
contaminate
the
heads.
•
The
use
of
a
120-minute
cassette
tape
is
not
recommended.
Frequent
switching
of
the
tape
operation
mode
can
result
in
the
tape
becoming
entangled
because
this
very
thin
tape
can
easily
be
stretched.
•
Keep
cassettes
away
from
equipment
with
magnets,
such
as
spea¬
kers
and
amplifiers,
because
their
magnets
could
cause
erasures
or
distortions
of
your
recorded
tapes.
•
Protect
cassettes
from
dust
by
storing
them
in
their
cases.
Even
minor
dirt
or
dust
could
contaminate
the
heads,
resulting
in
noise
and
sound
drop-outs.
•
Do
not
expose
cassettes
to
direct
sunlight,
extremely
cold
temper¬
ature
or
moisture.
