Recently purchased a GORF upright....right away as gameplay starts, the space invader guys leave dotted trails behind them left to right...i was told this is a bad chip on the CPU board, caused by heat...i guess what Im looking for is any known solution...the chip apparently is not reproduced, so finding a new working CPU board, or board set, may be my only option...thanks for any help!

It's possible that it is the custom chip but I don't think so. Seems I remember one having that issue but just can't pull it out of my brain. If you happen to have another pattern board you may go that route first. Could you post a few pictures?
