SECTION
VIII.
OPERATOR'S
CONSOLE
CONSOLE
FUNCTIONS
Type
220-1
Console
The
220-1
console
operates
in
two
modes:
1.
2.
Peripheral
Mode
-
Functions
as
a
peripheral
device
which
utilizes
a
read/
write
channel
under
program
control.
The
program
illuminates
the
TYPE
indicator
and
causes
the
keyboard
to
become
effective
when
data
is
to
be
entered.
Printouts
are
under
program
control
only.
Logging
Mode
-
Functions
as
a
logging
typewriter
which
is
logically
disconnected
from
the
central
processor
to
allow
the
operator
to
make
essential
notes
about
the
operation
of
the
program.
The
console
is
switched
from
one
mode
to
the
other
by
pressing
the
LOG
push-button.
This
button
is
illuminated
only
when
the
console
is
in
the
logging
mode.
The
typewriter
keyboard
is
effective
only
when
either
the
LOG
or
the
TYPE
indicator
is
illuminated.
PERIPHERAL
MODE
When
the
LOG
indicator
is
turned
off,
the
console
typewriter
may
be
operated
under
pro-
gram
control
as
a
peripheral
input/
output
device.
The
console
control
allows
the
typewriter
to
be
addressed
by
a
program
through
a
read/write
channel
for
typing
out
messages
from
the
pro-
gram
or
for
entering
parameters
into
the
central
processor.
In
the
peripheral
mode,
the
type-
writer
keyboard
(except
the
Carriage
Return
key)
is
not
effective
unless
the
TYPE
indicator
is
illuminated.
LOGGING
MODE
At
the
risk
of
delaying
the
program,
the
operator
may
log
while
a
program
is
running.
In
the
logging
mode,
the
typewriter
operates
off-line
and
appears
busy
to
all
central
processor
in-
structions.
Thus,
if
the
program
attempts
to
address
the
typewriter
while
the
operator
is
log-
ging,
it
will
stall.
The
program
can
test
whether
the
console
typewriter
is
busy
by
executing
a
PCB
instruction.
The
logging
mode
is
effective
only
when
the
LOG
indicator
is
illuminated.
This
button
is
either
illuminated
or
turned
off
each
time
it
is
depressed.
Illuminating
the
LOG
button
does
not
cause
the
read/write
channel
to
be
released
(if
one
has
been
assigned).
Type
220-3
Console
The
220-3
console
(see
Figure
8-1
for
illustration
of
console
control
panel)
operates
in
three
mutually
exclusive
modes:
1.
Peripheral
Mode
-
If
the
STOP
indicator
is
not
illuminated,
the
console
typewriter
operates
under
program
control
as
a
peripheral
device
utilizing
a
read/write
channel.
Except
for
the
L
key
and
the
Carriage
Return
key,
the
typewriter
is
not
effective
unless
the
TYPE
indicator
is
illuminated.
