For years now I have had a Simpsons Arcade machine UK version (much bigger than US version) and a couple of extra jamma pcb's (Teenage Mutant Hero Turtles and Robocop). But I have never got up the courage to swap the PCB's. For one I wouldn't know where to start and also the fear of damaging something. Is it just a case oh removing the old board and slotting the new one in? how do I tell which way around to put it in? I have seen a few pictures of the insides of cabs and it looks like you have to mount the pcb to the case some elastic looking stuff?. x_x

Also the sound has been going for quite some time now it goes very quite or off completely some times. I think the speakers just need replacing or rewiring, what else could it be?

Lastly does anyone know of any sites in the UK that sell jamma pcbs, marquees, parts etc?

Paul.
