TECHNICAL TIPS
Troubleshooting Switch Common
Circuits
STEP 1: A) Disconnect P.O. Edge Con-
nector J-7 from the main
logic PCB.
B) Turn off all program swit-
ches at location F2 and F4
on main logic PCB.
C) Turn rotary switch for
score replay level to zero.
STEP 2: A) Check D9 Pin 8, switch
common, to insure that it is
a high logic level; also that
there are no pulses.
B) If there are pulses present,
check for a solder bridge on
switch common or a pro-
blem in the coin, start, slam
circuit, or a shorted option
switch on the main logic
PCB.
STEP 3: A) Check 09 Pin 13 to insure
that it is active when the
coin, start or slam switches
are pressed. It should be
high, pulsing low. 09 Pin
12 should be low, pulsing
high when any one of these
switches are closed.
WARNING: Most switch common pro-
blems are caused by careless main-
tenance on the playfield with the
POWER ON. If-40 volts DC is accidentally
applied to the switch common, it will
surely result in serious circuit damage
and down time.

FOOTBALL STARS
PLAY GAMES
ON CREDIT
''Ten dollars in tokens, please,'' re-
quested the enthusiastic player, "and
put it on my Master Charge," he add-
ed. Yes, this is a common occurance at
Scores arcade in Dallas, Texas, where
Master Charge and VISA bank cards
are accepted for five dollars or more in
tokens. According to Fred Rosen,
President of the new game center, the
credit card use is beginning to catch on
at Scores. "I feel it will be a significc;1,nt
factor within a year to increase the
overall collections.'' He explained fur-
ther that since the use of credit cards
to play video and pinball games is new,
it will take time for people to take ad-
vantage of the convenience.

THE INTeRSANK CARD.
i.
A family will often charge $10 to $20
worth of tokens for an evening of play
according to Mr. Rosen. At this loca-
tion the average charge is ten dollars.
The credit service is advertised in some
radio spots and posted at the location.
It was noted that weekly credit sales of
tokens has increased regularly since
the service was first introduced.
When using credit card service, the
game center must pay a percentage of
these sales to the bank card organiza-
tion. Nevertheless, as at stores, cus-
tomers will most likely buy more
tokens and play more games when
they can use credit cards. Fred Rosen
reports that the use of credit cards is
working well at his arcade. It is cer-
tainly an innovative concept to con-
sider for game centers using tokens.

BALL match. It was broadcast on the
local Evening Magazine program
(aired Feb. 15) and regular news pro-
gramming as well. After long com-
petitive and fun play, Bob Boyd was
declared the champion of this local
Super bowl.
