My last word on this: The photo shows just how bad the situation can be. The off-the-shelf controller is mounted onto what looks like a tailor made pinball I/O module. Now what will happen if in 12 months the off-the-shelf controller has a simple change to relocate a socket? You can now scrap all your I/O module boards that it mounts onto. A redesign of the I/O board is now required, and you hope your PCB manufacturer places a high priority on a set of replacement I/O boards.
PS.
Keep it clean - this is not pinside. Don't make wild assumptions about people - or maybe I'll send you my CV. I don't know who the reference to old man was meant for, but I would also take it as a compliment, having seen enough niave youngsters easily turned red faced. But in this case, my middle age may not fit your attempt at an insult. Always talk to people in these forums, as if you were talking face-to-face.
