KEEP THEM INFORMED
The Journal is not inexpensive,
but if it even once helps you keep
a game going over the weekend
at a hot tavern spot or the like, it
pays for itself -in just one issue.
Information is valuable. Getting
information to the troops or at
least making it accessible is also
valuable. Like any currency, you
can't spend it if it ain't in your
pocket. So, some thoughts on
keeping the techs up to date.
To be effective, a good tech needs
two things:
The background is the accumu-
lated knowledge of experience
and study. It is the general infor-
mation that pertains to everyday
situations. Ohm's Law, why
there are =#=!, =#=2, and =#=3 Phillips
screwdrivers, NPN, PNP,
Darlington, TTL, CMOS, flip-
pers, playfield wax, green felt,
coin acceptors. The learning
comes in when specific informa-
tion becomes available, such as
service bulletins, tips and sugges-
tions from others sharing the ex-
perience, etc. Learning also be-
comes important when a new
technology arrives. This indus-
try, being as competitive as it is,
incorporates new ideas as quick
as it can. When it does, we have
to roll with the punch. When
juke boxes shifted over to CDs,
we needed to learn about CD
players. They are fundamentally
different from phonographs.
I remember other changes. Evel
Knievel jumped the canyon of
mechanical pins and landed us
on the digital bank. Kicking and
screaming, we were made to
learn about digital systems, neon
displays displaced the score reel,
programming replaced jumper
wires. Then color took over the
video game world, composite
video became RGB. Redemp-
tion showed up, we had to learn
about ticket dispensers, motors,
and stuffed animals. It goes on,
as it always will.
Some thoughts on keeping up to
date. Make sure all your techs
see this magazine, and if you sub-
scribe to other trade magazines
like Replay, make sure any tech-
nical information there is also
available. Wherever you go or
do business, your distributor for
example, find out if there are any
technical/ service mailing lists to
get on. Also get any manufac-
turer info you can the same way.
Take advantage of any seminar
opportunities you can. Institute
an in-house service bulletin. I
have done that in the past and
found it very effective. Bulletins
can be a way for individual techs
to share solutions to problems
they solve in the field, saving the
next guy some time. Game pro-
gramming guidelines can be in-
cluded. Bulletins are an effective
way to insure that policy and
operational changes are brought
to the tech's attention. Consider
a master set of manuals for each
tech and a book of general refer-
ence. The manual set might in-
clude a set of common monitor
schematics, general program-
ming and codes and service in-
formation for the models of juke-
box on the route, dollar changer
service data or at least fault codes,
if you operate redemption in-
clude diagrams for the brands of
ticket dispensers in use.
For me the general reference is a
thin three ring binder, but it can
September 1997
be a big manila envelope or
whatever else you like. I would
include a list of important and
relevant phone numbers, com-
pany phone list, perhaps a loca-
tion list including manager or
other contact names. Do you
have accounts at the hardware
store or any place? Make an ac-
count number list. If policy per-
mits, a key list may be helpful,
especially for access keys and
seldom used numbers or one of
a kinds. Some of us have very
involved key systems, while
some use just one master key and
others still leave the random keys
that came with the game. We al-
ways carried a standard parts kit
(plus whatever else the individual
liked to carry), so if you do this
as well, make up a listing of what
is in the kit. You might make up
a technical data list, such things
as specs for the transistors in your
kit, part subs you like to use, so-
lenoid coil equivalents or subs.
If your operation has policies or
procedures that can be confused,
put them in the book. The col-
lection schedule for the month,
especially if it changes. Which
locations may or may not hold a
key or a collection. Sky is the
limit. Metric-English conversion
chart, foreign currency exchange
rates, chili recipes... Maybe not.
Leaming the basics. Take a tis-
sue to the ol' glasses, because the
only real way to learn electron-
ics involves a lot of reading. The
only way to learn how to work a
screwdriver is to pick one up and
turn it, but the job provides
plenty of opportunity for that.
Book learning can even help you

with that screwdriver. Look
through a good tool catalog like
Techni-Tool or Jensen, and you
will find that what you thought
were just Phillips screws might
have been Posi-drive or Reed-
Prince. You may well find tools
and test equipment you were
unaware of, better ways to do the
job.

formation
to the
troops or at least
making it acces-
sible is also valu-
able. Like any cur-
rency, you can't
spend it if it ain't in
your pocket.
It would be great if everyone
could go to the local community
college and take the courses in
vocational electronics. In fact I
recommend it. But today we are
going to discuss learning on your
own. If you don't actually have
any interest in electronics, it will
be difficult to learn it. The ab-
stract concepts and the relation-
ships involved are just not like
memorizing the state capitals.
We will assume the interest is
there. There is no best book for
learning the basics. Each of us
responds in unique fashion to any
text. Some of us like a no non-
sense text that doesn't dawdle on
any point, while others like to
move along slowly with lots of
explanations and examples. I
personally learned most of my
electronics from ARRL' s Radio
Amateur Handbook. It discusses
most areas thoroughly, but it does
so in minimal fashion, no gener-
ous explanations. You might pre-
fer a gentler text. There are
many intro-to-electronics books.
Visit the library, the bookstore,
the electronics parts store or
catalog(most have a book sec-
• tion), even Radio Shack. Thumb
through a book looking for its
general flavor, the attitude, would
you be comfortable with the ap-
proach? Self study courses can
be good. I have used a few of
the old Heathkit courses and
liked them. Whatever books you
chose, you need to get the basics,
all that Ohm's Law stuff, AC,
DC, circuits, transistors, logic.
Don't skip the chapter on mag-
nets and light bulbs. It may seem
stupid but the concepts are im-
portant.
Newer books leave them out, but
older texts cover vacuum tubes.
That's one of my strongest area,
personally, but you need not
dwell on it much. Don't ignore
it completely. Every video game
you operate has a big vacuum
tube in it, the picture tube.
Beyond the basics lies the more
advanced material. Generally
this is more specific stuff, mostly
centered on various applications.
More practical knowledge this.
More books. I learned basic logic
from the TTL Cookbook, and I rec-
ommend it. There is also a
CMOS Cookbook. Each of these
