A Word About Parts & Shipping
By Exidy Customer Service
Frerront, califomia
Everyone has heard the phrase, "TIME IS
r-mEY," and this has never been more true
than in today's coin-op industry. Whenever
parts or supplies are needed for repairs,
every minute lost to down-time translates
into lost earnings. When deciding which
method of transport is "BEST," consider
the following:
1. How many dollars does the piece earn
daily when it is fully operational?
2. How many dollars are saved by going a
slow "low-cost" shipping method?
(UPS-SURFACE)
3. How many days could be saved by
shipping a faster method? (UPS-BLUE,
UPS-RED, EXPRESS MAIL, etc.)
4. And finally, how many dollars are
represented by the difference of shipping
days versus shipping costs?
EXAMPLE
Here is an example to illustrate the
differences:
3 pound package from Frerront, CA to
Baltimore, MD
1. Gane earns $100 per week. (earning only
$14.28 a day avg)
June 1987 (4)
UPS-BLUE
Lost earnings $18.56 + shipping $6.00 =
$34.56 Total Cost
UPS-RED
Lost earnings $14.28 + shipping $14.50 =
$28.78 Total Cost
A difference of as much as $31.33, (or
more), \IAJuld be forever lost if
UPS-SURFACE were chosen over the faster
shipping methods. As you can see the s called "cheaper" rrethod (UPS-SURFACE) 1.s
in fact a much more expensive alternative
when compared with lost earnings.
Additionally, when faced with this
decision early in the week, UPS-BLUE and
UPS-RED are an even better bargain, as it
can make the difference of getting that
game back into the arcade before the next
weekend (which are typically the largest
earning days).
Renerrber - Don't be a Penny wise and a
Dollar foolish. When in doubt, have it
sent UPS-BWE, or work through the nurrbers
and have it sent UPS-RED. You'll make more
money in the long run.
We at EXIDY are very much aware of the
costs involved in down-time. It is of
paramount importance to us to ship parts
orders as soon as possible, and we take
every opportunity to turn them around on
the sarne day it is received. We hope our
efforts are helping you to reduce your
lost earnings due to down-time.
2. UPS-SURFACE shipping rate is $2.99 (4+
days in-route)
3. UPS-BLUE cuts 2 days from ship time.
($6.00).
4. UPS-RED overnight cuts 3 to 3.5 days
from ship time. ($14.50)

SHIPPING METHODS
Murphy's Law #904
UPS-SURFACE
Lost earnings $57.12 + shipping $2.99 =
$60.11 Total Cost
If you can keep your head when all about
you are losing theirs, then you just don't
understand the problem.

Fremont, california
IM741 Power Re-Direction fvk>d.
Following is our specifications for
CROSSBCM--type audio board modifications.
'Ibis modification will reduce comµ:ment
stresses and provide for better
reliability.
'Ibis change should be made on '!OP SOCRET
games purchased before March 1, 1987. ('!OP
SOCREI' games sold after this date have
already been modified.)

It is also being recommended for CROOSBCW,
CHEYENNE, ~CKSHOT, CA'ICH-22, CHIU..ER,
and CLAY PIGEON. Al though these GUN games
will function fine without the rood, it is
recornmended as a preventative rreasure and
will increase long term reliability.
TOCHNICAL DFSCRIPI'ION:
'lbe supply voltage to the LM741 is being
redirected from +18V/-18V to +12V/-12V,
also a current limiting resistor has been
added. (See circuit diagrams.)

PRCX:EDURE:

A 1k ohm, 1/ 4 watt resistor is added to
the base circuit of Qll and Ql2. Also, the
supply voltage is switched from +/-18v to
+/- 12v.
Low

POSSIBLE CAUSE: 'lbe reason for this
service note is that this component may be
overlooked in trying to find the cause.
CB, a 47 microfarad at SOVOC capacitor may
have opened up.
I encountered this problem shortly after I
was told about it at the A01E show in New
Orleans this past March. I have
encountered this cap as being the problem
only once before, but other technicians
seem to have encountered this cap as being
resµ:>nsible for low +SVOC several times
in the past.
