The cab I'm working on is so close to being complete I can taste it. Last night a friend and I were wiring up all of the switches to the i-Pac controller. We made sure everything was properly grounded first, and I followed his lead since he had already successfully done the wiring on his own cab (which was up and running in the background as we worked no less). After we had grounded all the switches daisy chain style, we decided to wire up just the joystick and buttons on the player one style and plug it in for a test. My computer immediately gave a 330 error when booting up Windows that a keyboard was missing. Needless to say nothing worked. We couldn't get the iPac to even function as a pass through for the keyboard when we unwired it. Thinking maybe the port on my PC was bad, we tried plugging in just the keyboard and rebooting - no 330 error, no keyboard error. Now we're strongly suspecting my iPac is bad. We plug it into my friend's cabinet, which was already working with his iPac, nothing. Oddly enough the green led on my iPac will light up when he hits the 4 switch on his panel (select, start, player one - I don't remember which) but not any other button. We even tried reseating the chip in my iPac thinking maybe it was just loose, but that's a no-go. Replacing the chip isn't a problem, I'm just wondering if this has happened to anybody else before. It's frustrating to have the painting done, the shelves built, the wiring done, the marquee lit up, the panel ready, and then be stuck with no working cab due to one faulty chip. :P
