I had optical mice on an IBM XT (1980/81). Sun computers came with opticals in the 4xxx line.

I have both LED and Laser now. Laser is nice. The new optical are anywhere optical.
The new (last year or year before now maybe) Laser has 10x resolution IIRC.

Funny, I've been using optical mice for at least 15 years... Nice to
know they were invented only 5 or so years ago! I was ahead of my time
- that, and my steam-powered computer : )

An optical mouse in 1991? You sure about that? Was it IBM compatable?
I never seen such a thing. You wouldn't happen to still have that
mouse would you? I'd like to see it. I have a growing collection of
vintage computer stuff and look regularly at salvage stores to see
what old goodies I can find. I rarely find an optical mouse. Most
of the ones I do find are USB which makes them a bit newer than 1991
for sure. Around 1991 I was a bit behind the times with my 386sx
16Mhz machine. It came with a ball mouse. I don't recall even using
a mouse much back then. I was still running DOS and most of the stuff
I did either did not support a mouse, or hot keys were a much faster
way to maneuver.
