Unfortunately, Black Knight wasn't the only machine suffering from it. I went back a couple months later and there was no improvement unfortunately.
I have mixed emotions about it. On one hand, I feel like it's a shame to put these machines out there when they're not really working properly. On the other hand, I feel like I'm looking a gift horse in the mouth. Just having a chance to see some of these old friends again is really worth the price of admission. And I can't even imagine the herculean effort it must take to keep things working as well as they do. Heck, new flipper coils are like $15-$20 a pop. Not sure what the expected life span is, but these machines get a LOT of use so it's got to be just insane and expensive to keep things in tip-top shape. And I really do respect and appreciate that.
