Quoted from Pin_Guy:Very true, the software should be smart enough to realize that all the rows are bad and give you the "check F114 and F115 message"
Note that the ROM (OS part of the ROM image, specifically) will ALSO give this message if it does not see the 'Always Closed' switch closed.
Not having your coin door interface board connected will cause this, since the 'Always Closed' switch (24, I believe?) is on the CDI.
