Important
Whenever
your
IBM
PCjr
does
not
respond
as described in this book, go
to Section 6, "Testing your IBM
PCjr"
Someofthe
colors
shown
in this
book
may
be
different
than
the
colors
on
the
screen. This
happens
because aU
televisions
and
displays
do
not
produce
the
same
colors.
If you are asked if your screen looks like an example in
this
book,
the
question
reaUy refers to
the
shapes
of
the
color
blocks
and
figures.
To
operate
properly, your IBM
PCjr
keyboard must be
in
front
of
your
IBM
PCjr
and
no
more
than
6.1
meters
(20
feet)
away.
Your
IBM
PCjr
and
the
keyboard are connected by an invisible beam, so don't
place an5rthing between them that will block that beam.
Getting
Started

Do
not
turn your IBM VCjr power on yet.
Let's
take a
minute to review what should happen when you do.
It take's a few seconds for something to appear on the
screen.
Whenitdoes,itlooks
like
this:
This
screeniscalled
the
IBM
Color
Bar
screen
and
it
appears for a few seconds. While it does, your IBM
PCy/-
is checking itself to be sure it is ready to go to
work.
After
your IBM VCjr has checked itself
and
finds that everything is working correctly, you hear one
short beep
and
the screen changes.

Getting

These keys are called cursor control keys. In computer
talk, a cursor is a character (sometimes a blinking line
or
block)
that
shows
you
where
you
are
on
the
screen.
You
can
moveacursor
up,
down,
right,
or
left
with
the
cursor
control
keys.
In this part of your "Keyboard Adventure," P.C. will
pretend
to
beacursortoshow
you
how
to
move
around
the
screen.
Each
of
the
cursor
control
keys
moves
P.C.
in
the
directionofthe
arrow. If a
cursor
control
key
is
pressed
and
released,
P.C.
will
move
one
position
and
stop. If
the
keyisheld
down
P.C.
will
continue
to
move.
Getting
Started
2-9
Move
P.C.
to
the
top
of
the
screen
by
holding
down
the
Cursor
Up
key.
(This key has the word "Home"
under
it.)
Did
you
hearabeep
when
P.C.
reached
the
very
top?
A
beep
sounds
whenever
P.C.
goes as
far
as he
can
go
in
one
direction
on
this
screen.
Now,
let's
find
out
what
that
strange
object
is on
the
left
side
of
the
screen.
2-10
Getting
Started
/-N
Using
the
cursor
control
keys,
move
P.C.
through
the
object
on
the
left
sideofyour
screen.
(Make
sure
the
object
disappears
from
the
screen.)
HINT:
If this
doesn't
work
the
first time
you
try it,
just
continue
to
move
P.C.
around
the
object
until it
vanishes
from
the
screen.
What's
happened
to
the
box?
Is
thatasecret
door
that
just
opened?
Do
you
suppose
there's
any
connection
between
the
object
and
the
unlocking of
the
door?
Let's
see
if we
can
solve this mystery.
Perhaps
P.C.
can
help
us!
Using
the
cursor
control
keys,
move
P.C.
to
the
opening
of
the
box.

Getting
Started

Now, if you were P.C., wouldn't you be curious enough
to
peek
inside
the
box?
2-12
Getting
Started
Move
P.C.
as
far
down into
the
box
as possible.
What
happened???
As
you
can
see,
there's
no
need
to
worry.
P.C.
is
back.
Getting
Started

In
fact,
P.C.isready
to
guide
you
through
another
adventure.
Let's
find
out
what
P.C.
wants
you
to do.
Perhaps
if
you
press
the
cursor
control
keys again...
Press
each
cursor

key
once.
Do
you
have
any
