I just wouldn't buy one with original 5v boards unless all of the light boards have been replaced. All of those games should have exhibited issues by now. I think around September of 2013 JJP switched to 7.5 unbuffered boards, then moved to 7.5 buffered boards and finally to the 2.0 board system that is used in all JJP games today.

Many owners of 7.5 unbuffered and buffered games have never had board issues. Going on over 4 years here with 7.5 unbuffered boards and have never, knock on wood ECLE apron, had an issue.

That's great to hear. I think my game was built around the same time, haven't had any issues. Good to hear a reboot will clear lock ups if they occur.

I use Wizards Mist and Shine on the playfield to reduce the chance of static build up (stuff works great on all games) and just in case have WOZ and all my pins plugged into APC surge protectors which plug into APC voltage regulators.

Amazon sells it, great stuff.

A 2.0 kit should be made available at near cost as early WOZ owners are why JJP is in business today.
