Hello Pin Folks,
Been slowly working on a Black Knight I acquired and the main issue I'm battling right now is that it seems that none of the settings are saved when I power the machine down. For example I change things to set the machine to free play -- and when I cycle the machine all that is lost. Does anyone know which chip/leg I should measure with my multimeter to check for voltage when the machine is off (and what the voltage should read)? Looking at the schematic it looks like IC19 is the CMOS chip -- is this the correct one that stores the settings when the machine is powered off?
On a side note, does anyone know if the dip switches on the main board should be set a certain way for Black Knight. I don't see the manual mentioning them doing anything.
Much thanks.
