This project is nearing completion

I finally to the cabinet moved to my house. I have the control panel completely wired, the coin door is wired with lights and coin slots work. I have the original marque light wired and working as well. I mounted the computer and my converter box inside and built and mounted my amplifier for the sound that drives the stock 6x9 cabinet speaker. I still need to wire in my main power switch and construction will be finished. I still have to do some tweaking in the computer, I haven't been able to get my trackball working in mame yet, but I haven't spent much time on it yet either. My kids love it and I am really going to enjoy having this. To me this is an awesome setup, to be able to play hundreds of arcade games on one machine. I don't have a room or a basement to have a full blown arcade with dedicated machines, I only have room for one. If anyone has any pointers on getting the trackball to work post it up. Thanks!
