Yikes... if the horizontal roller won't work (by that, I take it you mean
the roller that the mouse's ball rolls by friction), you probably have an
electrical problem; Have you tried taking the mouse apart and looking into it?

I know I had a problem with my M3 mouse: used normally, it almost refused to
go in a certain direction (I forget which), but rolling the roller directly
worked fine.  So I opened up the mouse, and discovered that there was a spring
on the roller that probably wasn't stiff enough.  So I shimmed it up with a
few layers of file card, and since then it has worked fine.  (The mouse mat
helps too.)

Probably not feasable at all.  I tried a friend's Amiga mouse on my C128 once;
although the connector fit into my joystick port, I wasn't able to get any
response out of using the mouse.  (I guess I should be grateful that I didn't
destroy my joystick connector!)
