That would be the normal 500/2000 mouse. I have a 1000 mouse here and it will work on any Amiga, but you would have to put something under the machine to install the mouse since it would hit the table.

I just keep it incase I get a 1000 someday (or trade it for something else).

Never throw out working equipment.

MacG4 are you going to take pics of the Amigas? Curious about how the 1000 looks.
