mechanism are all
part
of a unitized assembly
enclosed in
a
sealed,
protective,
non-removable housing. Your ProFile drive is
portable.
lf
you
handle
your
ProFile
with care,
you
can easily
move it from
one
localron
to another.
You may stack
your
ProFile on top ol the Apple lll or
place
it
on
top of a desk close to
your
computer.
Never,
under
any circumslances,
place
the ProFile
drive
on a thick carpet or any other surface
lhal mrght
obstruct lhe air vents on lhe bottom of the unit.
As a
general
rule,
you
should
place
the unit on a hard surface
where it
is
convenient
to operate and alr flow 1s not
restricted.
ProFile differs from a flexible
("floppy")
disk drive
in
that the
ProFile
media consists of
rigid
disks
rather than floppy disks. Since the
ProFile
disks
are enclosed
in a
sealed
housing, they cannot be removed or
interchanged
and therefore
cannot be damaged
or lost
as
floppy disks
can.
The main
advantages
ProFìle has
over a
floppy drive are:
.
Much
greater
data storage capacity
(lt
takes about
70 floppy
disks to store the
same
amount of data as a 10 Meqabvte
ProFile
disk
drive).
.
Higher
reliability.
.
lmDroved oerformance.
ProFile
ìs
controlled by
the Apple lll's
Sophisticated
Operating System,
usually called
"SOS".
The
SOS
automatically
keeps
track of
files,
saves
and
retrieves information, and does a multitude of other housekeeping
.
tasks. The few special commands needed to
manipulate
files and
use
the drive are described
in
the
reference manual for the
particular
product
or
programming
language being used,
lor
example
Apple lll
Business Basic.
