Hi !
I´m about to go and pick up a Sys 11-Williams Game that I bought recently- a 1987 Big Guns.

Now, I'm currently studying the operators manual that I've downloaded and also scrolling through tech-tips here and on other forums on that particular model.

Are there any special warnings to be considered, that are not obvious to the beginner, things to avoid around that certain pin when firing it up for the first time ?
It is supposed to be in working condition.
Is there anything that I should order now that usually is going to need changing right from the start- apart from rubbers and balls ?

Thanks for any help !!

Check all your fuses to make sure they are the correct amperage and type (regular vs slo-blo). Replace the batteries on the MPU and check for corrosion, better yet move them off the board entirely with a remote battery unit or NVRAM.

I think the best course of action is to get as familair with the game as possible before you pick it up. Then when you do go to acquire the game, take the glass off and start a game. I like to manually check all the switches etc to make sure that those are working correctly simply by rolling the ball manually through those targets. Does it score properly? If so then I would proceed to buy.

Keep in mind that the system 11 games are very fun generally speaking but will need to have some updating to keep them going for a long time. A good example would be to remove the power supply board and reaplce the capacitors on that board. The electrolytics is what i am referring to. Very inexpensive to do and Great Plains Electronics will have all you need. I just did this on a system 11 shuffle alley i recetly acquired. Easy enough to do yourself provided you have some decent soldering skills.

As long as the game is in reasonably good shape, you should be in good to go.

Thats my .02 worth.

You cannot go wrong with any system 11. They are my absolute favorite series of games. Great bang for the buck and original themes. Always inspect the interconnect board on system 11. I have never owned one that didn't need at least the GI connectors replaced. Most needed jumpers on that board to repair lifted traces. The interconnect boards are readily available in the US anyway. I do not know about over seas. I always repair them but if bad at least a new one can be purchased

Thanks a lot guys, that sounds like a good start - and I really appreciate
the tech-hints, I will check the boards carefully.

Yes - I really fell for the unique look of BG- and I think the soundeffects are very good and entertaining- compared to a lot of other games from the mid- or late eighties. From what I understand some people dislike the absence of pop bumpers and ramps on BG. Even so, I think those cannons and habitrails sure look cool.
