Title: Who has an M that can answer a couple of programming questions? Post by: jbshocks on April 15, 2012, 07:20:51 PM I have the 1986 M model that is working fine But I can't seem to program it. In programming mode if you change something like attract mode on or voice and you cycle back around does it stay changed? Mine will change all of the settings other than credit but once you cycle back around the settings are gone. I am changing the no to yes by jumpering the jackpot reset switch as I don't have a key.
