i closed out another post that questioned dbv200 software/firmware issues. I have a good working dbv200 - that works fine in a 10mhz game - when I try to use it in a game with a 16mhz board - the bills reject - some wait for a few seconds others immediate. The 16mhz board has the SP1146 which is type 2 for 16mhz board and uses ID023. Bill head has all bit swx OFF. Transport is good - bill box is good - all components work in other games - only fly in ointment 16 mhz cpu. YES I have 10 mhz boards - would love to find a use for the 16 mhz boards i have.
