Thats my question? Do I need to tie the trackball into the I-Pac with an optipac?  

Because I want to order the Trackball with a USB/PS2 connection, which I am assuming you can just plug into the computer?

Thanks

If you buy the happs trackball with usb/ps2 interface you do not need an optipac.  Plugs in the same way a regular mouse would.  This is exactly what I did on my first cab.  Easy.

That is fine, they are totally separate entities.

The IPAC is purely a keyboard encoder, so use that for all your digital inputs (as you correctly plan to do).  As far as Windows is concerned the IPAC is just a keyboard.

The trackball interface will make the trackball appear as a mouse in Windows, so you can use this for Window itself, and MAME / anything else which normally uses mouse input.
