Thanks for that Rick. I have managed to source the displays courtesy of other forum members :). Tony from the pinball shed has supplied a driver board, and David Gersic as said he should be able to provide a sound and power board. The only real challenge now is going to be the CPU board, so if anone comes across one please let me know.
I am still waiting confirmation from David G as well, but he has been a little slow in responding at this stage, I am sure he has a lot of emails to sift through.
I have send Fred a message too. Thanks again guys, always a wealth of information and help.
