and
peripherals
PROM writer
Mount PROM writer
directly on CPU.
Securely tighten
the mounting screws.
The
PROM
writer
provides
C20
users
a
means
of
storing
their
programs
on
microchip,
as
opposed
to
cassette
tape.
This
way
the
program
can
be
“permanently”
saved
or
easily
duplicated
for
use
elsewhere.
The
EPROM
(erasable
programmable
read-only
memory)
chip
can
be
written
and
then
later
erased
by
ultraviolet
light.
The
PROM
writer
has
functions
to
write
the
contents
of
the
CPU
memory
to
an
EPROM
chip
and
vice
versa,
and
also
to
verify
the
contents
of
the
EPROM
against
the
CPU
memory.
However,
these
functions
of
the
PROM
writer
work
in
“normal
write
mode”
but
not
“high-speed
write
mode”.
The
PROM
writer
can
be
directly
mounted
on
the
C20.
It
is
important
that
when
using
this
unit
mounted
on
the
C20,
the
I/O
cable
connecting
the
CPU
and
expansion
I/O
unit
not
be
connected.
Otherwise,
the
PROM
writer
may
not
operate.
As
the
EPROM
chip,
use
Type
ROM-H
(#2764
or
the
equivaient).
The PROM writer may not operate
when mounted on the C20 if the CPU
is connected by cable to an
expansion I/O unit.
Graphic programming console
A-14
The
graphic
programming
console
is
a
quick,
visual
way
to
write
programs
using
ladder
diagrams
and
instruction
words.
The
user
presses
instruction
keys
and
other
control
keys
on
the
keyboard.
In
response,
the
symbols
appear
on
a
screen
on
the
portable
unit.
The
graphic
programming
console
is
available
in
two
types.
One
employs
an
LCD
(liquid
crystal
display)
for
the
screen
whereas
the
other
uses
a
CRT
(cathode
ray
tube).
The
CRT
type
is
referred
to
as
“CRT”
while
the
LCD
type
is
referred
to
as
“GPC”.
Both
the
CRT
and
GPC
store
programs
onto
cassette
tape
and
load
programs
into
the
CPU
memory
using
the
peripheral
interface
unit.
