I have an early direct print standard bought nib and did a lot of research and found that the 7.5 volt boards go out just as often as the 5 volt,that was not the problem ,jjp just swapped to 7.5 because they did not know what to do and it did not help,what did work was buffered boards 5 volt or 7.5,they are both much better than non buffered,I paid for the entire set of buffered boards and swapped them all,I now have the a very reliable early woz,love the game and it was worth it to me,
I would just except that boards that are not buffered could go any time from static,games on carpet and winter time dryness is worse,the mist n shine may help wth static,I wish jjp could come up with a kit that could buffer existing boards and not have to buy the entire buffered board set
