VIDEO POWER SUPPLIES
WHICH
To
STOCK
&
QmcK REPLACEMENT
Just the other day, I was confronted with an interesting choice. As it turned out, not a
difficult choice for me, but for some of you -a choice that you may want to consider.
TYPES
I'm speaking of the decision to
purchase and stock the new
"computer" style power sup-
plies that come in the new
dedicated videos these days.
Or, if you have been doing
video conversions (and who
hasn't?) or repairs, to stock the
older (but still reliable) "peter
chou" style supplies. This is a
choice for you to make. Based
on a couple of points that I will
explain, you'll probably see
your choice clearly, too.
YoUR DECISION
"To stock or not to stock" the
new style "computer" supplies
and/or the older "peter chou"
supplies is the question.
repair or upgrade older videos,
such as Atari's Pole Position
and Williams' Joust, Defender
and Stargate. That's two big
plusses for the "chou" supply.

In fact, you lose nothing if you
replace the "computer" type
supplies with the "chou" sup-
ply. Now, knowing this I only
have to stock one type -the
"peter chou" type supply. For
me, the choice was easy.
CHOU SUPPLIES
I do alot of video conversion
kits, in which I install the "pe-
ter chou" type supply. So, for
this reason I am going to have
to stock this type supply. I also
use the "chou" type supply to
QUICK INSTALL
Here, now is some general in-
formation concerning install-
ing and/or changing supplies
with a "peter chou" type power
supply.
L Find a good location in
which to mount the sup-
ply.
a) A good location
is one that allows you to
mount the new supply
in such a way as to use
the available wire har-
nessing -without add-
ing wire extensions.
2. Locate the AC output
to the computer old sup-
ply.
a) These (usu-
ally) black and white
wires will also go to the
marquee lights and the
monitor isolation trans-
former.
b) Disconnect the
AC hook-up from the old
supply and prepare the
wire ends for connection
to the new supply. Do
this so that the AC line
