Womble Posted May 10, 2009 Share Posted May 10, 2009 Blimey - you have been busy - I can provide a photo for this one tho. Dodgy LS151 at 10E gives this effect... http://i40.photobucket.com/albums/e230/Womble76/DSCN4723.jpg That was the last of many faults on Scratcha's board back in Feb http://www.aussiearcade.com/showthread.php?t=12419&page=4 Quite a pleasing fix that one too, never got round to moving it to the repair log section tho. :) Welcome to AA by the way - where abouts in the UK are you from? I am originally from Cambridge/Newmarket area. Link to comment Share on other sites More sharing options...
scratcha Posted May 10, 2009 Share Posted May 10, 2009 Quite a pleasing fix that one too, never got round to moving it to the repair log section tho. Never got round to posting a video of the working game neither. But it is working a treat.... Link to comment Share on other sites More sharing options...
