"Have you seen Coin Mechanism's CC-16
and model CC-40 coin comparators. They're
totally electronic and compare the players
coin to a coin you supply (it clips into the
rejector). I was impressed, but the prohibi-
tive cost of $50 to $80 dollars a unit kept me
from purchasing any."
"Have you seen or tried the comparators?
One thing in particular I liked about them
was that they fit into all existing coin doors
and can run off of 12VDC or 15 to 50 VAC,
(yes AC). Coin Controls has a similar prod-
uct, but it only fits into their special coin
door and is priced at $100+ a unit. When I
asked them why they didn't design it to work
with other brand coin doors they got all
snotty and explained that with a superior
~" product like theirs, compatibility was un-
necessary!"
"The electronic coin acceptors are beyond
my price range when the good old made-in-
the-USA, Coin Mechanisms metal mechs
work just fine. When it works, I don't fix it,
and we're learning to stick with the tried and
true."
"I've had many problems with the plastic/
metal Coin Controls acceptors used on
Leland's Quarterback and Team Quarter-
back. Players normally insert many coins at
once to rack up enough time to complete a
game. If 1 coin gets stuck in the cradle,
others will logjam behind it requiring a serv-
ice call. So far, no solution."
"CoinCo. Plastic. I'm on tokens in all loca-
tions and fmd the plastic much more reliable
~ and trouble-free."
"Coin Controls plastic acceptor. Extremely
reliable except under very dirty (dusty) con-
ditions."

SYMPTOM
Amp blows fuses on initial power up or the
amp has a very distorted output.
CURE
More than likely the amp has one of the four
diodes that form a bridge rectifier either
shorted or open. Replace bad parts.
SYMPTOM
Audio output has a buzzing crackling or
hissing as well as possibly being weak.
CURE
One of the two power supply filter capacitors
has failed. These are the two mounted on the
top side of the amp nearest the transform-
ers. Measure the AC ripple across them and
replace the defective part(s). The AC ripple
should not be more than about 1 volt RMS.

NEC Vs Nintendo Hom.e Gam.es

The May issue of Electronic Engineering
Times announced that NEC has just re-
leased their own home videogame system.
It's called TurboGrafx here in the US ("PC
Engine" in Japan) and compares to Nin-
tendo as follows:
Although another home system is not what
we need right now, I hope NEC is successful.
The article stated that NEC's new system is
specifically targeted at Nintendo.
designed for it. I've also heard rumored that
an Arcade version is being tested right now
in the San Diego area ( so it looks as though
NEC will even give Nintendo a run for their
money even on the PlayChoice System).
Jeff Peters, owner/ editor of Electronic Game-
Player, a home/ arcade players magazine,
told me he has had this system for review at
his house for several months now, and Nin-
tendo really pales by comparison. It also has
an option that allows five players to play
simultaneously, if the particular game is
The new SEGA system (called Genesis) was
shown at the CES show in Chicago last~
month. Nintendo not only didn't show their .
16 bit system, (which is rumored to be
available in Japan), but made no mention
about it.
