CONSOLE CONTROLS
AND
INDICATORS
Two
rocker-type
switches
provide
control
over
the
destination of data.
Two
spare switches can
be
used
for
control of
auxiliary
units.
Console
indicators
provide data
entry
indications
and
a
power
on
indication.
Individual
switch
and
indicator descriptions are given
in
Fig. 1-8.
THE
KEYBOARD
The
4023
keyboard
arrangement
is
similar
to
a
typewriter keyboard.
Both upper
and lower
case alphabetic characters
can be
generated.
Non-shaded
keys provide
func-
tions
similar to a
typewriter,
and
are
used
solely
for entering data. Special
keyboard
keys
that
provide functions not
normally
related
to
a
typewriter
are
shaded. Their
functions
are
explained
in Fig. 1-9.
CONTROL
AND
FUNCTION KEYS
This
group
of
keys
provides
a
dual
purpose:
1.
Functions such
as editing,
cursor
posi-
tioning,
data
transmitting,
reset
functions,
etc.,
are controlled
by
these switches.
A
description of
each
switch
is
given
in
Fig.
1-10.
2.
These keys can be
made
to
function
as
a
numeric keyboard by simply
pressing
the
NUM
LOCK
key.
Thus, those
familiar
with
adding machine-type keyboards
will
find
this
a
convenient
means
of
entering
numeric
data.
