Eventide
phased
into
production
a
new
CPU
board
with
a
single
ROM
socket.
The
earlier
boards
held
a
maximum
of
128K
of
operating
system
code.
The
new,
single
socket
can
hold
a
ROM
with
up
to
512K,
allowing
room
for
code
expansion.
In
order
to
install
operating
system
4.0
or
greater,
the
CPU
with
this
socket
is
necessary.
If
the
customer
has
an
Argus
with
the
appropriate
CPU
board,
the
operating
system
upgrade
may
be
field-installed
following
procedures
in
this
section.
If
a
customer
wants
to
upgrade
from
the
old
CPU
to
the
new
CPU
so
that
he
can
install
new
versions
of
the
software,
the
Argus
must
be
returned
to
Eventide
for
upgrade.
The
upgrade
involves
a
CPU
board
exchange,
and
parts
from
the
old
CPU
are
used
on
the
new
one.
The
unit
must be
re-tested
and
re-
documented.
All
instructions
in
sections
3.4
and
3.5
remain
applicable
except
for
those
involving
the
physical
handling
of
the
ROM
itself.
The
ROM
is
installed
in
a
PLCC
socket
and
the
procedure
for
removing
and
replacing
it
is
detailed
below.
