Hah,
I just got the J-PAC & X-Box to J-PAC Cable w/ PS/2 cable. At first it wouldn't work, but I found out later that I also needed the X-Box controls adaptor to supply power to the J-PAC via the PS/2 cable. I figured that I wouldn't need it as I wanted to use the xbox controllers instead of my CP. For awhile I was getting away with using the PS/2 port on my pc, but that was a pain in the ass, especially with 3 little kids wanting to poke around inside while the cab door is open :S. So, being the mad tinker that I am, I just took an old mouse and cut the PS/2 cable off, found the pinouts for +5v & ground for it and soldered it to the appropriate pins on the J-PAC. It worked like a charm! It has a great picture and I use a couple of pc speakers for sound. It was fun running the xbox media center to watch anime & other media content on my cab. Played Halo 2 on there for a hr and it was awesome as well. Going to get another set up for my other cab as well. 2 extra monitors for Lan parties, I just know my friends will be fighting over who gets to use them

. Just thought I would share. Laters....
