The ones I've tried have worked but there's a number of different Mac
Plus mice. 6 or 7 years ago I opened up a couple dozen of them and
found about 6 different designs. I remember being surprised that a
mouse with one part number would have several different internal
designs. I wonder if Apple subcontracted them and the subcontractors
designed their own mechanism?
Anyway there have been enough reports of Mac mice mot working with the
IIe and IIc to surmise one of the designs is incompatible.
Or that old Mac mice have a tendency to have a wire broken. ;-)
