    It did, but i cleaned it up with vinegar, fly leaded, done nothing more too it. mpu4 mod 4 with ay chip. been perfect, just started to play up, sometimes pays out less the 50p, keep playing then it works then it dont, hit an miss to when it works. the board defo needs attention, ive not repaired the tracks or anything. even thought works, id assume it needs the tannys, the diodes the caps & track repairs. ill await the rtn of the mod 2s and then look at it. its working for the minute,

    i think ill stop with straight swap out of odd bits lol, its getting too technical for me now and my limited skills. but i will have another go, one day. how do people clean the acid up these days, or is it better to just remove everything inspect clean then refit new parts, vinegar bath was they way, but does more harm than good ive read. i did Vinegar these and cleaned them dried them before i started, i tested before and after clean and repair attempts too. left in airing cupboard for a few days, to make sure completely dry before i re tried them, now my potluck board has started to play up, wont fire 50p sometimes. so that needs tlc too now
