Even required for them to operate at all.

B.t.w., while we are discussing low volume demand for mice in the
early 80's:

Do you remember those "mouse holders" that were sold to PC users who
only occasionally used their mice for some specific applications?

I assume most of those has been thrown away in the 90's. Would somehow
be kind of nice to have with a C64 mice or similar :)
