The word on Saitek keyboards(?) n-key rollover

pex:
I'm not sure why this information is so painful to get, especially when the Saitek website heralds such things as "Saitek leads the world with high performance products for PC gamers and stunningly designed peripherals for all PC users."

Hi,

I am afraid the maximum outputs out keyboards will do is 5.

--- Quote --- I appreciate the response but I am not sure that it satisfies my inquiry. I am looking to know the smallest number of keys, of all the combination of keys, I can press and get blocked.

Such that, if you're telling me I cannot exceed 5 keys with any combination...and we'll pretend I can press "qwert", "asdfg", and "zxcvb" without getting blocked...if I press "jkl" and get blocked, I have a 2-key rollover keyboard, because out of ALL the combinations of keys I could ever press on a keyboard, SOME combination blocks me at 3.

Please clarify.

Well I can press qwer without getting blocked and jkl. Trying to type lop will block lpd is fine. From this then there is a 2-key rollover.

--- Quote ---That's the kind of information I'm looking for, thank you. It's an amazement to me that rollover isn't a standard marketing point, even if not a major one (especially for those in the 'gaming' sector, among others).

Please pass along that it doesn't make sense for a company who makes all of the following claims (from ) to market parts that don't meet those claims.

"All these products are designed /by gamers for gamers/, to help them get the best out of their favourite PC games."
"Saitek leads the world with high performance products for PC gamers and stunningly designed peripherals for all PC users."
"Saitek designs and manufactures consumer electronics products which improve the user’s multimedia, gaming and other PC experiences. Constant innovation, superior design and a /high degree of functionality/ make Saitek products the choice of computer users around the world.
"Saitek stands for superb design and total control."

Being a gamer, claims like "by gamers for gamers" and "high degree of functionality" are troublesome to read if they aren't true. The rollover issue brings this point to prominence.

Again, thanks for the response.

For a "gaming" keyboard, the only rollover that matters is 6-key in the QWEASD block, and that block not interfering with any other rollovers. (And, technically, anything running on USB won't meet that requirement, so that last requirement is obviously not that important.)

Huh? Only if you're just going to play certain fps games and not fiddle with the settings. It's probably a decent starting point for low-end gaming keyboards but if it's going to be branded a gaming keyboard then it really should shine in all games.

Racing games for example use the arrow keys. Try holding down a vertical and a horizontal arrow key and pressing 0 on the numpad. It doesn't show up on my model M so I'm pretty sure having n-key rollover there would be beneficial too.

And then there are spaceship games than use WD for acceleration, the surrounding keys for functions and the numpad for steering.

Any top-end gaming keyboard should allow any combination of keys I can actually press.

EDIT: I've had a similar deal trying to get the rollover information of the Cherry G80-3000. I emailed two companies that sold them, one told me cherry had told them that the G80-3000 had full n-key rollover but they hadn't tried themselves. The other told me that cherry had told them that the G80 didn't have n-key rollover because adding the diodes would push the price up. I have sent an e-mail to cherry over the weekend but I haven't had a reply yet.

Unfortunatly this kind of blatent lying is pretty much everywhere in the PC market. Apple's recent "Thinnest Laptop" claim is a good example but there are many, many others.

Well, it seems that FPS (and RTS and MMORPG, but those are more mouse-centric) gamers are who most gaming stuff is marketed towards...

Hmm, the only bias I've noticed in that direction is for some mice and mousepads, most gaming peripherals (keyboards, headsets, monitors) seem to be marketed towards gaming in general.
