i have modified the assimilation mac trackball to work with thw amiga
this has two buttons and they are wired together to work on the mac.
basically you have to isolate thr right button by cutting two traces
connect it back through the circuit and bring it out on a separate
line. there are insufficient wires in the cable provided. a patch
connector also has to be made. i posted mac and amiga pinouts
previously. the only thing that threw me is that the right button
has to be connected to mouse 3 on the amiga. if there is any interst
i will try to post a summary of the mod. i think if you take the
trackball apart and stare at it you will see what has to be done.
it is nice not having to save space on a desk for the mouse
