Are you sure? AFAIK, all Amiga mice are dumb
quadrature mice with two
buttons,
If you'd ever dare take away my third button, I'd make the rest of your life
very short and painful, Peter. =)
and their interface consists of 5V power, ground, four
quadrature
signals (2 for X and 2 for Y) and two button signals.
Pin 5 takes a third button if you have one. Many mice do.
A Sun mouse has a
proprietary encoded interface that uses three (or four?) wires. I suppose
you could rig one up to a serial port, if you wrote a suitable driver
(might also need a level translator).
Now, there's a funny project: removing all the encoding circuitry and rewiring
the Sun mouse in order to make it an Amiga compatible quadrature mouse!
