TECH: Coin Switch Help

[Mark Szlemko]

Hello Everyone!

I have a question. My Super Pac Man has a strange malady. When I
lightly tap the coin switch, the game does a credit like normal.
However, If I happen to press the switch too far or hold it for more
than an instant, the system just keeps crediting up, and letters appear
where it says Credits. What's up? Is there any way I can fix this
without replacing the switch?

Thanks!

My Super Pac does exactly the same thing, as does every Super Pac I've
ever seen, so I think it's a bug in the programming rather than in the
switch. I may be wrong.

If the switch stays closed too long on Gaplus, you have to turn the game on
and off to fix it - the board locks up with a "Coin Stuck Error". I'd
rather it had the Super Pac problem.

Likewise my Super Pac does the same.................

That is no programming bug.

It was implemented intentionally as an "anti-cheat" measure.

Those who have been around the block will know what I mean.

Engineer's interpretation:

A paid-for falling coin (neglecting the obvious friction and
non-linear path the coin takes) will have a linear speed of
about 1.5 m/s after traveling the 15 cm pathway from the
coin entry slot to the coin switch actuator wire. It will
be able to trip the coin switch and exit the switch pathway
in about 10 ms. Hence the concept of a "fast pulse".
(In actuality, it will be traveling much slower.)

A less-than scrupulous person attempting to simulate the
falling coin would have to be able to duplicate the timing
in order to "fool" the program into believing that a paid-
for coin has fallen through the coin pathway. If they were
an amateur or were too slow, then the program would detect
a "slow pulse" and then displays "CREDITAA" and locked-up.

"CREDITAA" never occurs with normal use.

The term "CREDITAA" became jargon with some ;-)

OK, quick question how come when I generate a fast pulse and it displays
creditAA I can still play my game?

Wouldn't it make more sense to have the game not start, instead of just
making funny noises?

Am I wrong on this?

Just curious,

I am not 100% sure, but I think that this occurs if and only if:

1) the coin switch pulse is removed quickly and/or

2) you start up a game right away.

If you continue to allow the coin switch the be held low or do not
start up a game, I think the game will lock up and then you will
be unable to start a game. Try this and see if it the case.

I'll try it this weekend and let the group know.

I have seen this also on my neighbors Super PM and since he and I both do
Arcade repairs I replaced the coin mech. and it has stopped. well do that if
you want to fix it up

I finally played around with this. After the machine registers a 'Credit
BB' it will not start a new game, but it will let you finish the one your in
the middle of.

I stand corrected.............Sorry.
