Installation
If
your video
display
unit
is
an
RGB
monitor,
such as Tandy's
CM-8
Analog
Monitor
(26-3215), follow
these
steps:
1.
Turn your Color
Computer
3 over so the
bottom panel
is
exposed. Locate the
RGB OUT
connector.
2.
The
RGB
monitor
has a computer
cable wired
into
the
back
of
it.
Plug
this
cable
into
the
RGB OUT
connector
on
the
bottom
of
the
computer.
3.
Guide the cable through
the
channel so
it
is
out
of
the
way. (See
Figure
