Hi all,
First, pictures are worth a thousand words.

AND THIS:

EQUALS Analog and joystick arcade controls on your XBOX based arcade!
The Max Shooter keyboard and mouse adapter for the XBOX allows you to use a standard ps2 mouse and keyboard to play your favorite games on an XBOX. Combine that with a Keywiz or Ipac (Both which show up as ps2 keyboards) and a ps2 trackball (a mouse input) and you can move with your joystick and aim with the trackball!
The standard keymapping for the Max Shooter is below, however, they Max Shooter is reprogrammable, just like the KeyWiz or Ipac, which should allow you to come up with any combination of controls you want.

I got the idea while playing my Futurama XBOX game. I was depressed that I would not be able to play Futurama on my Futurama themed arcade when I got this brainstorm.. ;-).
Hopefully, someone out there will be able to use this idea, I know I will. Heck, with a ps2 switch I may even be able to have the mouse and Ipac hooked up to both the computer and the Xbox...
Good luck.
Jeff
