I'm looking to get my JP restored soon(ish).
One thing that occurred to me ... is it possible to replace the series or soldered mechanical switches in the ball trough with one of the WMS 6 ball optos? Surely this would make it much more reliable.
Can it be hacked like this? It surprises me somewhat that no-one has designed and made up an off the shelf board to do just this ... JP and other DE games seem to have a bunch of issues with their trough switches, often ... and it's a total mess down there, compared with a couple of opto boards.
