at the moment I can have only access to an old G4 mac (os x 10.3.9). I
can get it, if this test is meaningful to you.

Agreed! I heavily use keyboards 12-16 hours/day and would wear out
Dell, HP and other keyboards within 3 months. I have been typing
since the early 1950s (IBM electric typewriter) and have absolutely
NO RSI or other problems due to proper posture/sitting while at a/the
keyboard. The Unicomp keyboards are fantastic; I have the SpaceSaver.

The Customizer can be seen/ordered here:

SpaceSaver version of the Customizer:

Larger version (wider/taller, black only):
<http://pckeyboards.stores.yahoo.net/customizer.html>

Here's my setup : <http://thadlabs.com/PIX/Thad_desk.jpg>
I've been using the SpaceSaver now for 18 months and it's still in
perfect condition, no glitches/gotchas or regrets. :-)

Won't help even if you get the right adapter, as the Model M
lack a key to use as Meta. The 104/105 key Unicomp keyboards have the
necessary keys, although they unfortunately carry the "Windows" logo.

A few years ago, it was actually possible to use genuine Model M
keyboards with an adapter, as long as you loaded a driver to map the
left Alt key into Meta. Unfortunately, this option disappeared with an
update from Apple.

I have two or three model M keyboards left, but I normally use
105-key Unicomp keyboards with USB interface (of which I have 4 :-)

Works great with Macs, as long as you have a keyboard layout
specification that matches the keyboard.

just spent 2 hours and discoverd the answer. Apparantly, and i was
surprised to discover, that this is a common problem to keyboards,
basically all keyboards, that they are not capable of detecting some
combination of 3 more more keys simultaneously pressed!

This is called n-key rollover problem. For a clear explanation, see:

http://www.microsoft.com/appliedsciences/AntiGhostingExplained.mspx
http://www.microsoft.com/appliedsciences/content/projects/SideWinderX4.aspx
http://www.microsoft.com/appliedsciences/content/projects/KeyboardGhostingDemo.aspx
http://en.wikipedia.org/wiki/N-key_rollover

you can use the above app to test your keyboard.

On my 2 Microsoft keyboards, if i just hold random multiple keys,
usually it'll detect at 6 keys simultaneously held.

But if you start to be pick what combination you press, the following
will fail:

LSfhift RShift x
LSfhift RShift /
w a s d held then pressing many other keys will usually fail too.

Quite a interesting finding.

i didn't bother to whip out my Apple keyboards and other kbds for the
test, but i assume it pretty much behaves the same.

the question is, what are some keyboards on the consumer market that's
really n-key rollover? i.e. as these article says, that every key has
a diode?
