It seems that people are quick to
write in to complain about a bad
experience with a company, but
never to give praise when a com-
pany responds promptly and ef-
fectively. So here's
a letter to applaud
Taito.
SYMPTOM
I was having some
difficulties with a
new Two Minute
Drill. The game
would randomly
give incomplete
passes, even be-
fore the ball was
thrown.
SOLUTION
Finally, Juan told me he would
check with other Taito techni-
cians to see if someone might
know more about this game's
problem. Taito's
answer to all of
this was to send

SYMPTOMS
Blue video lines and no
game functions at all.
CAUSE
Bridge rectifier bad on
power supply. CR13 is a 7
amp bridge that gets too
hot and is under-spec'd for
this application. The
bridge may, in fact, get so
hot as to unsolder itself.
SOLUTION
Remove CR13 and install
a 25 amp bridge rectifier
with a metal housing.
Wire it with 18 to 20
gauge. Remove R16 from
the main board.
