Found this on rgp:
**I set up a webpage detailing how to do this for Street Fighter 2, but
I'm going to paste it here so that all the people with Stargates and
all these other fine pins have it in the archives once and for all.
This and more information is available at:

I've been asked this so many times by so many people that have found
my
website, that I've decided to write it up here.
Yep, there's a free play option on the Gottlieb System 3s. Don't
dispair,
lots of people have trouble with it... in fact, my Stargate had a tiny
credit button mounted on it because they didn't know how to set the
freeplay!
All you had to do is open up the coin door, and on the left hand side
you
will see a little PCB. There's a slider switch to put the machine into
tournament mode. Put the machine into tournament mode, and a menu will
pop up on the DMD. (if it's already in tournament mode, I think a
quick slide
back and forth on the switch will bring the menu up if it doesn't come
up
automatically when you open the coin door)
What you want to do is set Free Play to YES and set everything else to
Normal. Then just close the coin door. Can't remember if the menu goes
away or not.. if not, just power off and back on and you're good to
go.
The start button should now flash during attract mode.
As you play the machine more, there's a nice feature with that
tournament
mode. You can customize the settings to make it harder or easier in
both
regular mode and tournament mode. Essentially, you can have two
variations of the rule set that you can quickly toggle between. You
lose the
freeplay when you're not in tournament mode, but it's just something
to keep in
mind.
Personally, I have everything set factory but have the match feature
turned off, specials award extra balls, and my extra ball levels are
150mil,
300mil, and 450mil and have the self-adjusting turned off.
Hope this helps someone!
