I bought a Logitech wireless keyboard and a trackball and ran their
Unifying program to make the keyboard run in parallel on the

won't talk to the dongle it came with.

"Unifying program" -- wants Windows, right? Maybe available for
Apple's OS-X as well. Certainly not for a Sun workstation running
Solaris 10. :-)

Enjoy,

The keyboard and trackball remained 'Unified' when moved to a
different Win7 computer. I suspect the program copied the trackball
dongle's recognition code to the keyboard.

I just operated the cursor simultaneously with the trackball, the
touchpad on the wireless keyboard, and another wireless mouse. The
only wireless interference I've seen was from an aftermarket laptop
power supply that also jams the converter box for my old TV and shows
a wild party of spurious radiation on the spectrum analyzer.

I don't own anything Mac or *nix to try it on. At Mitre I had a
Windows PC, a Mac, a Sun and a Novell network in my lab, set up for
different CAD tools. Windows was by far the most versatile if not the
absolute best for every task. The Mac was particularly difficult to
add custom circuit boards to, not for the NuBus which is easy but for
the complex driver requirements. Windows doesn't like the user
executing low-level I/O instructions either but it allows anything in
DOS, which is still in there. I don't type fast or well enough to be
comfortable with Unix.

In fact the DOS underlying Windows 7 is rather nice, and almost fully
compatible with long NTFS file names etc. I've been using DOS batch
files instead of NTFS scripts to automate my backup process.
