Unicomp (http://www.pckeyboard.com/), the people who bought the Model M
design from Lexmark, currently make a keyboard with a buckling-spring
mechanism, which is very similar to the IBM Model M, has an embedded
TrackPoint III, and Windows keys.

On my PC, I used an old Wang keyboard, a model 724. I really like that
keyboard. I also have some of the IBM PS/2 Model M keyboards, the
clicky ones. I like those too. I bought a PS/2 to USB adapter, but it
would not work with the Wang keyboard. Also, with other keyboards, I
don't have an Open-Apple key (pronounced "Meta"). If I connect a PC USB
keyboard, the Windows key serves this purpose. The problem here is that
the only PC keyboards with a Windows key are the membrane type. In
other words, if I want to get a decent, yet compatible keyboard, It
looks like I'll have to build it. Besides, I love projects like these.

Actually, I've been planning on building my

tracking down old, broken keyboards from terminals, etc. to get
keytops
and switches from, and I am going to canniballize a cheap PC USB
keyboard for it's encoder chip and associated circuitry. Basically,
I'm
going to build a new key matrix from real switches, to replace that
membrane and rubber disc thing modern keyboards use. I've done stuff
like this before, rewiring a very old PC keyboard to replace a broken
TRS-80 Color Computer 3 keyboard. With any luck, I'll have something
that won't wear out nearly as fast as others, and be comfortable to
type on as well. The only thing I might run into is contact bounce. I
don't know if there is anything in a USB keyboard to deal with this,
as
I don't think membrane keyboards have quite the problem with contact
bounce as mechanical switches do. Any ideas?
I know Mr. Duell may not like my suggestion... but why not just find
yourself an IBM PS/2 'clicky' keyboard and use that, plugged into the
PS/2
keyboard port on the back of your computer? Or are you unlucky enough
to
have a machine that doesn't have a PS/2 keyboard connection? Sure,
it's
not the same as the keyboard on, say, and ADM-3A, but it's 'more
authentic' than modern keyboards.
Of course, sometimes I like the fact that my keyboard is fairly quiet
when
I'm typing on it. It may still be louder than my other machines in the
room, but it's nowhere near as obnoxious as a 'real' keybard.
