Wico Trackball to Mouse Hack

[tman2k]

Hello,

I am planning on buying a Wico 2 1/4" trackball, and hack it to a mouse.  However, they have two versions...active high, and active low...which one do I need?

Thanks!

I used the active low for my hack.  I did not get to choose as it
was a used ball but it worked just fine.
