Hi all,

Just wondering if someone can help me out, I am working on a Enhancement
for my HSII which someone has already conceived however I want to make some
changes to the way it works.

The Enhancement is the adding of a real traffic light to the pin to work
with the one inside the game, I have the schematic from the designer on how
to control it however his design has it working in attract mode which I
don't want.

What I would like to know is can someone tell me of a point in a WPC-95
where I can get a signal from to drive a Optocoupler (MOC3010) to in turn
drive a Triac to switch the Enhancement Off during Attract Mode and On
during Play Mode, I am sure there is a part of the Machine that powers down
in Attract but I have been going over and over my Schematics and cant seem
to find anything and I don't really want to start probing around my boards
because I really don't know where to begin looking.

If anyone has some ideas I would like to hear them, thanks in advance.

Kevin

Hi Kevin.

You can use the flipper relay enable signal on the power driver board as
the replay is only enabled during game-play. The signal is designated
'T7' and leaves the board at J111 pin 3. Since is is a TTL level signal,
put a small gate or small signal transistor between T7 and the optocoupler.

That's a tough one. I was thinking maybe you could hook it to the GI
circuit with a comparator to sense the GI powersaver. That would
unfortunately turn it off during the game too if the GI is ever dimmed.

(is HS2 WPC-95?)

You might try contacting Joel at the Pinball Lizard:

http://www.pbliz.com/id20.htm

He did this very mod quite some time ago. Also
designed a board, but it wasn't offered for sale.

No, it's WPC-89

My mistake sorry, WPC not WPC-95

Would I not be able to drive a Triac directly using this source for
control.

No. I would suggest refering the control signal information back the
original designer of your triac circuit and have them make a suitable
interface (with some added protection for the driver board logic).

Ok thanks, I will send him some info and see what he comes up with.
