I bought a 6 slot cab last year and have only recently pulled the board out to get the battery replaced as well as give the slots a clean.How i didn't notice the wires like this when i bought it i don't know but everything works fine except for 2 slots that were making lines through the games...
I am in the process of changing my 4 and 6 slot motherboards from the current steel ones to alluminium.Having had somewhat of a marrathon game session recently i noticed that the steel covers get quite warm and it made me stop and think about the effect this could be having on the motherboards...
