I found this cool commodore mouse at the flea market, so I cleanded it out and repaired it.

My not-so pretty solder job. I accidentally lifted one of the pins a bit, but I put a bit of solder on it, so it should be good! :)

Oh that looks exactly like the mouse that came with my Amiga 1000 back in the day. Nice. Mitsumi of course.

Looks like the mouse I still have for my Amiga 500. The pinout is in the Wiki. There is no protocol: only leads in the cable from the rotary encoders and buttons.
The Amiga had counters for the mouse in one of the custom chips so all you had to do as a programmer was to read X and Y values as bytes from registers and compare with previously stored values.
