Death of the Amiga platform predated introduction of optical mice of reasonable quality by a couple years. The Amiga mouse was a box of problems, with non-ergonomic shape, crud-accumulating rollers and buttons dying after some intense use. Comparing to modern mice it was simply awful. (but still better than, say, Sun's optical mouse of that time, which required a special mousepad to operate and if you rotated the pad it would get all wonky.)
Is there some mod or adapter or such, that would enable me to use/modify/convert a common USB or even PS/2 mouse with Amiga?
