Working on a system1 and it seems to boot fine, tried every combo of dip settings on 17 and 18 and can't get more than 2 credits on it when tripping the coin switch, have a good battery with 4 volts on the 5101 at pin 22 wondering were to go with this one?
Ended up pulling the board, had a bad U4 spider, only one switch was not working, put another board in and all is fine, I'll dig into this one
later, last time I replaced a U4 I had to pull it from and old board, took me three boards untill I found a good one. U4 seems to be the death ofthese boards
