I've got one, it's definitely under rated. I'm having a problem and a question. How do I update the ROM? I know I can get the files from Stern, but I have no equipment to burn new chips and wouldn't know how. Anyone have either the equipment to do this or a suggestion on where to get new chips?
I'm having an intermittent problem with the right flipper dying for anywhere from less than a second to three or four seconds. Diagnostics isn't helping me as it always comes out OK.
Is there a way to clear out the service notices (like open switches) so I know that everything is starting fresh. This way I know if I need to address something.

How did you make out with the ROM upgrades, where they worth doing? Any noticeable improvements? I'm thinking of doing with mine as well.
