INTRODUCTION
Spectravideo’s
Expander
Unit
SVI-605
is
specially
designed
to
offer
convenient
and
flexible
expansion
of
the
SVI-318/SVI-328MKII
computer
unit.
The
Expander
unit
connects
directly
to
the
system
bus
of
the
SVI-31
8/SVI-328
via
a
50-pins
connector.
With
the
addition
of
the
SVI-605,
the
SVI-318/SVI-328
can
interface
with
a
maximum
of
4
different
peripheral
devices
and
two
floppy
disk
drives
at
one
time.
The
metal
casing
of
the
SVI-605
which
is
helpful
to
eliminate
EMI
(electromagnetic
interference)
provides
rigid
and
durable
casing.
Moreover,
the
most
remarkable
feature
is
the
built-in
floppy
disk
drive,
disk
drive
controller
and
centronics
interface
in
the
Expander
Unit.
It
is
ready
to
utilize
disk
basic,
the
most
current
CP/M
programme
(with
sufficient
RAM
installed)
and
hard
copy
printout
with
the
addition
of
Centronics
printer.
Before
using
the
Expander
Unit,
please
