There are several trackballs available that emulate a Microsoft mouse.
They come in both serial and bus versions. Serial is the most flexible
and potentially has the least compatibility problems.

The big problem with a trackball is dragging. With most trackballs this is
a two-handed or very awkward one-handed operation. Two trackballs that
may solve this problem (I have not tried them) are the new Mouse System
trackball with a button lock and the new Logitech trackball that is
designed so your thumb moves the ball. The problem with the Logitech
trackball is it comes only in a right handed version. The Mouse System
trackball appears useable by sinistral people. Both are new products
and availability may be low right now.
