Don't know jack about these machines, but thinking about getting some sort of slot mach for our game room so I've been following your posts.
From the way your first post described the symptoms, it struck me when I read through that pdf manual that was posted that it sounds like your machine is in the 'challenge mode' described about halfway through the manual... it read that only 1-3 tokens could be played, and ALL 150 spins MUST be completed, even if the machine is turned off, etc...
Again, I know nothing about them but your first post and that paragraph in the manual really struck me as very similar, if you've already ruled that out, just ignore this post.
