We have progressed a little on this project. This area shows the top right of the PCB and our replacement transistors for the top two CA3081 IC's

and Dean, this board uses the same parts as trhe original including the processor. We are on the track of a hidden stash of them BUT in most cases people building this board will have a processor from their corroded PCB that will likely be OK.


Replacement Pinball PCBs that remain faithful to the originals
