No Saint, I am not seeing it. It did stop after the third post. I know I am more sensitive to those dang captchas than most people. I was serious when I said it takes me a ton of tries to get it right. With some captchas you can turn down the difficulty level, that might help some, too.
On some of my boards I just ask the answer to "What is two plus two?" if they get the answer wrong they are probably a bot, or they are so dumb that you dont want them on your board anyway!

As for the machine, I never a butcher anything, although I can see where I implied that above. Whatever changes I make are always reversible. For example I would remove this control panel and set it aside, and fabricate a new panel to go in its place. This particular machine is not Jamma, so the entire wiring harness would come out and be set aside with the original board set. So, ten years from now, when Jaleco Naughty Boy becomes that lost gem that everyone has to have... I will be ready.
