> Also, did you know the qbert arcade cabinets contained a the free game wood block traditionally found inside pinball machines.

I did not know that and still am not sure that I understand, after Googling: is this a wooden block that provides audio/haptic feedback for "specials" (usually free games) unlocked in pinball games by achieving certain scores? If so, what was its use in QBert?

In QBert it "knocks" when the QBert character jumps off the edge of the grid. First, there's a sound effect that sounds like QBert falling, then a short time later a loud knock that sounds (and feels) like hitting the bottom of the cabinet at the end of the fall.

They're called "knockers"; generally the score threshold for a free game or "replay" isn't hard-coded but is instead based on the grand champion score, so depending on location they can very from very low to very high.
