Kensington Expert/Turbo Mouse for 128k/512k/Plus?

[JAG]

Did Kensington ever make a trackball for the Mac 128k/512k/Plus? I much prefer trackballs to mice with my classic Macs and have a couple ADB models for use with my SE/30's and even use them with my PowerBook G3's.

My understanding is that even though the mouse port looks like a DB9 serial port, it isn't. I wonder how hard it would be to convert the guts of a serial Expert Mouse to whatever protocol Apple used.

I don't know if they ever made one specifically, but there were adapters out there.  I think our own member bbraun has/makes an adapter to connect ADB to pre-ADB Macs.

Kensington made the Turbo Mouse from 1986 for the original Macs and for the Apple II (presumably with mouse card). Features include two buttons for left and right handed use, and a pass through port for a conventional mouse. A redesign appeared in 1988 which added multibutton functionality, with versions for ADB and older Macs. There were some competent clones too.
