Just an update. The $35 'Gaming' keyboard from Frys that touted
simultaneous keypresses.... didn't.... I ended up with the Gigabyte
Osmium keyboard and it's working perfectly. Now I'm just awaiting my
copy of GTA5 to be delivered next week. We'll see how buggy the initial
release is....

I'm looking at new keyboards. The interesting this is that my PS2
keyboard did not have this problem on my old box, I am using a
USB->PS2 adapter on the new box with the same keyboard, and I'm
limited to 3 keypresses. That almost makes it seem like a USB
limitation, or an issue with the USB->PS2 adapter, not the physical
keyboard.

My Microsoft Sidewinder keyboard (with NKRO) has taken a beating over
the years. I think they stopped making it though or something? Also
gives you the option to disable the windows key while playing games.
Most keyboards that have it that I used for gaming I popped it out,
but on the desktop it's actually an entirely useful key, so having it
disabled just while in game is much better.
Even for work, there are certain situations where I'll manage to jam
up my laptop keyboard which is entirely aggravating.

Here's a pretty good overview of nkey rollover:

but I like mechanical keyboards and ten key less boards. There
are cheaper keyboards with full NKRO.
From Wikipedia:
Certain high-end keyboards have "/n/-key rollover". This means
that each key is scanned completely independently by the
keyboard hardware, so that each keypress is correctly detected
regardless of how many other keys are being pressed or held down
at the time.^[3]
<http://en.wikipedia.org/wiki/Rollover_%28key%29#cite_note-TechWeb-3>
Most music keyboards use isolation diodes in theirkeyboard
matrix
<http://en.wikipedia.org/wiki/Keyboard_matrix_%28music%29>to
implement full/n/-key rollover (sometimes abbreviated NKRO),
making them immune to both key ghosting and key jamming.^[4]
<http://en.wikipedia.org/wiki/Rollover_%28key%29#cite_note-dribin-4>
However, to reduce cost and design complexity, most computer
keyboards do not isolate all keys in this way. Instead, they use
a matrix of key switches, without any isolation diodes, that
assumes that only a limited number of keys will be held down at
any given time. With these keyboards, pressing as few as three
keys can cause ghosting effects,^[4]
<http://en.wikipedia.org/wiki/Rollover_%28key%29#cite_note-dribin-4>
although care is taken when laying out the matrix arrangement
that this does not happen for common modifier key combinations.

Personally I wanted PS2 only keyboards for the longest

issues with USB keyboards (gone with 7 and 8).
The PS2 keyboards I had most definitely had the problem
you're talking about. Definitely in UT2004 where it
was VERY noticeable. I believe this G19s is my first
USB keyboard as far as I can recall.

That's what I saw, it was something about the
groups of keys that they put into the same 'read'
pattern. So you can't have multiple keypresses
from the same 'group', but USB had a limit of 6
simultaneous events. Some high end keyboards get
around that by having a Hub built into the
keyboard, and presenting it to the OS as 2
keyboards so they can get 12 events. PS2 did not
have this limitation. There seems to be a ton of
bad information floating around though.
This PC Came with a USB Keyboard that's still in
the box. Maybe I'll put that out and try it.

The bus has nothing to do with what key
combinations you can or can not push. It's in the
keyboard itself. At least that's what my research
told me.
I've used the G19s for quite some time, but
honestly the only PC game I've played in the last
~12 months is Diablo 3. I absolutely love this
keyboard for everything else, if that helps.

called 'N-Key' Issues. Apparently this is an
issue with USB Keyboards where only a certain
number of keys (or combinations) can be
pressed at the same time. It seems like PS2
doesn't have these problems. There are many
many sites on it, and lots of talk about fake
reviews/ bad specs for keyboards.
So, Anyone here have a recomendation for a
good Gaming keyboard (USB) that doesn't cost
$100's? Or is there a special USB to PS2
adapter to use? I just loaded up one of my
racing games, and found that I can't
accelerate turn, and hit the Ebrake at the
same time.
