Further, if he wants to stay away from 'PC
Clone-ness' in his design,
there are some pretty decent 3-button PS/2-interface mice from SGI.
The O2 workstation uses these.
I'm assuming that you're talking about the classic 3-button Logitech mouse?
It's my favorite mouse hands down, as it is the one that fits my hand the
best. My second favorite, the Apple ADB Mouse II, has one slight problem,
it only has one button :^)
The classic 3-button Logitech mouse was also used heavily by IBM, both on
RS/6000's and PC's, by DEC (I'm assuming on both Alpha's and PC's),
as
mentioned on SGI's, and I'm sure by others. I'm simply mentioning the
companies I own rebadged mice from.
The Keyboard for the SGI O2 is also worth mentioning, it's hands down the
nicest of the the PS/2 keyboards I own.
