There are dozens of games and variations for 905 boards. Might be able to help, need to know what game ROM's you have, like 21.4 is Wild Double Up, 22.7 is Double/Double Poker etc.
That's Pixels correct? I just picked up a machine and I think it had the manual but I'm not 100%. I need to run to my storage unit later and I'll check.
I take it winning pair means any pair wins as opposed to just a high pair?
I did try some random dip settings before asking here, seemed like my odds changed. For now I have them back where they were when I got it. Seems to eat more quarters that way so I'm betting its set to factory right now.
