2010-2013 we used sometime BONUS GENERATOR but only by NOVAMATIC slots machines... but 1. u need open front change 1 of 3 CHIP... is easy max 30 sec. operation - u use universal service keys (5$) but in big casinos = MISSION IMPOSSIBLE!!! 2. this slots machines i think no more exist by normal Casinos only by undergrands small like Chinese with 30-40 slots. If u find old NOVAMATIC with American Poker or Delphins i can send u contacts to CHIP (bonus generator) seller price think today by this old model maybe 200-300$ .
