I've done it a couple of times, only I used a
rather
"brute force" method... I was disappointed with the
low quality of modern USB keyboards, and I wanted
something better on my Macintosh. I got ahold of a
Zenith terminal keyboard from a surplus
dealer(unencoded matrix type), and I loved the feel of
the keys (same style keyboard mechanism as in the
Z100).
I have to agree about USB keyboards in general, the keyboard that
came with my G5 2x2 actaully isn't that bad (I use it on my IBM Thinkpad), I
just don't like the lack of a place to put junk above the keys.
For my last two Mac's I've used my 10+ year old Apple Extended Keyboard II
via an ADB-to-USB convertor. For several years I also used the ADB II
Mouse (replacing one worn out one), however, I finally switched to USB when
I switched to Mac OS X so I'd have 3 buttons for X-Windows.
Personally I consider mice to be as much of an issue as keyboards, the only
ones I really like are the classic 3-button Logitech mice used on numerous
workstations in the late '90's. I really wish they made a USB one that
size/shape with a scroll wheel.
