Boot
up
the
CP/M
operating
system
by
depressing
B
on
the
keyboard,
following
the
MON>
prompt.
'!he
red
light
on
the
right-hand
drive
should
light
up,
an
audible
click
should
be
heard
from
the
disk
drive,
and
then
a
message
announcing
the
CP/M
operating
system
should
appear
on
the
screen.
If
this
does
not
occur
within
5
seconds
of
pressing
B,
depress
RESET
on
the
computer
chassis,
then
dismount
the
disk.
(To dTsmount a
disk,
press
the
door
latch
further
to
the
right
until
it
springs
open.)
Remove
it
from
the
drive
and
make
sure
that
(a)
it
is
the
serialized
CP/M
2
disk
that
came
with
the
s¥?tem,
(not
from a
different
system),
and (b)
that
it
is
oriented
correctly
as
described
above.
'!hen
remount
it
carefully.
Depress
the
RESET
key
on
the
computer
chassis
and
try
the
~

again.
If
still
no
CP/M
message
appears,
repeat
the
process
of
RESETING,
dismounting,
checking
the
disk,
remounting
and
rebooting
once
again.
Then,
if
there
is
no
CP/M
message,
try
the
same
process
but
use
a
CP/M
2
disk
from
a
different
system,
or
if
you
have
none,
then
try
using
the
MOOS
diskette
that
came
with
the
new
system.
If
none
of
these
diskettes
will
boot
up,
the
chances
are
that
there
is
something
wrong
with
the
disk
subsystem
that
requires
the
help
of
service
personel.
If
MOOS
boots
up
but
CP/M
2
does
not,
then
obtain
a
replacement
CP/M 2
diskette
having
the
same
release
number
(not
necessarily
the
same
serial
number).
13.
When
CP/M
boots
up,
you
should
see
an
'A>
prompt
on
the
screen
following
the
sign
on
message.
Type
DIR
(return)
following
the
prompt.
(return)
means
press
the
RETURN
key.
You
do
NOT
have
to
use
capital
letters
when
typing
a
CP/M
command.
You
should
immediately
see
a
directory
of
the
files
on
the
diskette,
consisting
of
at
least
5
lines
of
names.
Make
sure
there
is
a
file
naned
BACKUP.

You
are
now
going
to
copy
the
cP/M
serialized
diskette.
'!his
has
the
double
function
that
it
tests
the
disk
drives
for
compatibility
and
it
gives
you
a
working
copy
of
CP/M -
the
copy
Which
will
become
the
Personalized
CP/M
2
System
Diskette.
Insert
and
mount
a
completely
unused
diskette
(or
one
whose
contents
are
not
needed)
in
the
left-hand
drive
(drive
B
in
the
CP/M
nomenclature).
Make
sure
it
is
a Dysan,
Scotch,
or
Maxell
brand
16-sector
diskette.
These
are
the
only
types
of
diskettes
you
should
use
with
the
Vector
Graphic
system
at
this
time,
due
to
the
high
density
of
storage
employed;
other
brands
have
been fot.md
unreliable
in
this
system.
At
this
time,
Scotch
seems
to
be
the
roost
reliable
of
the
brands.
