Speech
Synthesizer
U4
is
the
speech
synthesizer.
The
word-address-bits
are
presented
to
U4
on
pins
1
through
10.
The
load
command
is
active
low
and
appears
on
pin
23
of
U4.
The
audio
output
is
on
pin
14.
U10
is
a
serial
input/parallel
output
shift
register
and
is
used
to
load
the
address
bits
appearing
on
pins
3
through
10
of
U4.
U10
is
serially
loaded
by
the
microprocessor,
U5.

RP-8
Relay
Panels
Additional
useful
information
concerning
the
technical
operation
of
the
RFC-1
is
located
in
the
"Circuit
Description"
chapter
of
this
manual.
The
RP-8
relay
panels
receive
operating
power
from
the
RFC-
1
control
unit.
There
should
be
approximately
10
volts
DC
between
pins
14
and
15
of
JI
(or
between
pins
16
and
8
of
U
1).
With
a
telemetry
relay
selected,
the
current
consumed
by
the
RP-8
panel
will
be
about
33
milliamperes
and
this
may
be
checked
by
temporarily
removing
one
end
of
resettable
fuse
F2
and
inserting
a
milliammeter.
The
binary
value
of
the
selected
channel
should
appear
on
JI
of
the
relay
panel,
pins
11,
10.
9,
8,
7
and
6,
with
pin
11
being
the
most
significant
bit.
When
a
panel
is
"selected"
by
the
RFC-1,
U2
pin
11
should
go
low.
The
least
significant
three
bits
determine
which
of
the
eight
channels
on
the
selected
panel
will
operate.
U2
should
generate
this
information
and
pass
it
along
to
the
relay
driver
U3.
The
telemetry
relay
for
the
selected
channel
will
remain
on
as
long
as
the
channel
is
selected.
Control
relays
operate
only
as
long
as
the
control
tone
is
received
.
A
jumper
plug
should
always
be
plugged
into
one
of
the
"Block
Select
”
jumper
locations
or
erratic
operation
will
result.
If
it
is
suspected
that
a
malfunction
of
one
of
the
RP-8
panels
is
disrupting
system
operation,
remember
that
it
is
easy
to
"lift"
the
RP-8
panels
off
the
buss
one
at
a
time
by
simply
disconnecting
the
cable
from
the
panel.
Remember
to
move
the
12
VAC
connection
from
the
wall
plug
transformer
to
another
panel
when
necessary.
