I remember that Dale Luck, one of the original Amiga engineers,
sold a mirror-pad mouse, and I thought I remember him telling
me it was actually a Sun-compatible mouse. Of course, this
would mean compatible with Suns as of 1986 or earlier, and
not today's.

I'll readily accept that my memory of this could be faulty.
Perhaps a better question would be "Circa 1986, which off-the-shelf
mouse technologies were compatible with the Amiga mouse?"

I have an original GfxBase optical mouse on my A2000. The bottom
says "Mouse Systems - Manufactured by MSC Technologies, Fremont,
CA, etc. Model M4. MSC 40215-001/B S/N MSC CZ097242".
