I just tried my Logitech G15v1 and came up with QWAZX + ctrl + enter + shift

So six keys + modifier keys.

I'm afraid not.

so wait
you are misspelling 'fox', or spelling 'fox' prints 'fpx' on the filco?

Ripster was just making a joke by saying that the right shift key was too far of a reach for him to type correctly, so everything he typed with his right hand was one letter to the right. I was just being a **** by calling him out on spelling the other words incorrectly, but he got "fox" right.

Boards with a poor algorithm that can't track complex sequences of key presses/releases. (I.e. needs all keys to be released often it order to reset its tracking.)

fancy bullets!
anyway, i never thought about that. i dont think on either keyboard i typed it all the way through. i didnt think it mattered whether or not i take breaks. maybe that explains why some people get an E here, but not there (example)?

did it again on my HHKB and it still worked fine, but that's something people should remember when doing the test.

i had no idea keyboards worked that way... i thought it was much more 'momentary'.

i figured ripster was joking, but on this test when i make an error (and i do, no matter how slow i go) i just keep typing and get the right one next.

AndrewZorn · « **Reply #304 on:** Fri, 09 October 2009, 12:45:44 »

yeah, the ASX thing is incredibly disappointing. how can the model m be revered by UBERLEETPROGAMERs when it cannot handle this?

fortunately, aside from diagonal WASD+modifiers, i dont use many keys at once. anything that requires simultaneous use with crawling diagonally (talk, reload, change weapon, etc) i have mapped on my mouse.

EDIT i do think 6 is plenty, especially when modifiers dont count, but it just seems like a design limitation we should be over now that it is 2009.

this thread/forum needs a wiki or single post or something for the Ctrl+Alt+Shift+QWASZX+[beyond] and maybe LAZY DOG tests
or even non-standardized/lazy rollover test

unless there is one?

looking through 25 pages to find out if a keyboard has good rollover isnt great

i mean i would do the initial collecting from this thread myself

Keyboard: Zenith ZKB-2 keyboard (1989)
Interface: AT to PS/2
Operating System: Windows Vista
Max keys accepted: 32+ (As much as my whole palm can press)

If I use AT to PS/2 to USB adapter interface, it goes only up to 6 keys (limitation of USB specs).

I will conserve this keyboard until death do us part.

Thanks. Keyboard passed the mentioned keystroke in any order, including holding down Shift and Alt key all at the same time.

It passes ASX keys as well.

No combo I can try fails. I don't doubt I could get more than 36 if I could position my hands right.

Quote from: ripster;132523

Better to post Minimums though like whether it passes CTRL-QWAZX.

Pressing those keys (and hitting printscrn with my nose) involved some contortion. Max of 36+ may not be interesting, but so far that's the minimum as well. I have had zero issues with this one. Price aside.

If you have the same problem as me, do you still get it with a PS/2 connection? All my NKRO boards are USB only, so I can't test it.

nanu · « **Reply #323 on:** Wed, 16 December 2009, 10:44:55 »

Oh, here something that hasn't bothered me much, but something I noticed on day one of using my NKRO 87-cherry Filco Majestouch.

I insist on using it through PS/2 because on my system, the input lag is noticeably less than USB; the repeat rate is higher as well.

Occasionally, I get any of the shift/alt/ctrl/win keys stuck in its down state, in WinXP Pro 32bit. I have many global hotkeys with those keys as modifiers, so I tend to notice.

Mashing each independently corrects it, because I don't care to deduce which is stuck whenever it happens; just unstick them all.

At any rate, it's hard to reproduce at will, but seems to happen regardless of the application. The fastest way to induce it however, is to load up http://random.xem.us/rollover.html and register some silly keycount like 40+. Then switch to say, notepad, and notice that typing anything either does nothing because Ctrl is down, or you get uppercased letters because Shift is in its down state, etc.

Anyone ever get this sort of weird state? It might be related to this thread...

AndrewZorn · « **Reply #325 on:** Wed, 16 December 2009, 10:53:05 »

at http://random.xem.us/rollover.html when i do QWEJKL + LShift the Lshift doesnt show up, i know it is #7, but i thought shift didnt count...
even stranger is LShift + QWE + JKL, all of the JKL does not always show up.

still really liking the new cherry blue board.

nanu · « **Reply #326 on:** Wed, 16 December 2009, 11:13:21 »

itlnstln, I disable all Accessibility Options (including disabling utility manager to get another hotkey freed from Windows)

and all of those combos work here, AZ.

AndrewZorn · « **Reply #327 on:** Wed, 16 December 2009, 13:17:17 »

order matters. you can do [QWERTY version of] QWEJKL, then push left shift, and it show up on the above test? im getting some weird results. maybe it is time to restart.

I am kinda on the fence with this. Indeed, it does look awesome, but at the same time, it also looks unfinished.

Now that I have had a blank keyboard for a couple of months, I think I have reached my personal threshold for typing speed and accuracy. I'm still slow, I still wear out the backspace key, and I still sausage finger everything. I just can't stop thinking about where my fingers are supposed to go when I type. This sucks.

a good test for gamers is "wde" (or "waq") since that's a pretty common case of ghosting in fps gaming but it isn't widely known.
example: moving forward+strafe right+select a weapon

edit: also "efr" or "esw" if you use esdf instead of wasd

Quote from: ripster;145605

So in other words you have 1key rollover. That's pretty funny!

It's unrealistic though. It seems like the TVS Gold uses a fairly straightforward IBM-style keyboard matrix, no diodes and stuff (as I'd have expected). It should always manage 2KRO.

I'd suggest repeating that RTYU test while slowly adding one key at a time, preferably the same with FGHJ.

On my Cherry G80-3000LFADE with old-style Cherry matrix, pressing F - FG - FGH - FGHJ gives F - FG - - in the rollover test. The HEMDE with IBM-style matrix plus Win keys is no different (and will do the same on QWAS). My Model M seems to freeze output and signal an error from the 3rd character on, so the PC speaker starts beeping. Then again, it's on the PS/2 port while the others are on the USB adapter.
EDIT: OK, it's the adapter. A Model M connected there behaves the same as the Cherry boards, so I guess the error causes the adapter to discard all the currently depressed keys.

BTW, ripster, your Cherry doesn't do Ctrl-A-Q? Mine accept Ctrl-Shift-A-Q just fine.

An old-style Cherry matrix can also do that... but fails QWER. What about that?

..:: Free Radical ::.. · « **Reply #342 on:** Sun, 27 December 2009, 22:57:35 »

ok. on slowly adding it manages RT with RTYU and FG with FGHJ.

Even I was bemused at the 1KRO.
I was pressing down the keys simultaneously.

On the whole i am happy with my keyboard and never had problems while gaming.
Retails for Rs. 1150 (~ $25 ), very cheap compared to how the Filcos are priced.

Currently looking for cheap cherry browns but sadly there is a dearth of options in the Indian market.
There is another obscure manufacturer here named Ritcomp:
http://emitperipherals.com/keyboard.html
which uses Cherry MX switches, dunno which ones. Would be on the look out for em.

They do mention "non tactile" and 60+/-20cn on their web page. So that would be my guess too. It would be funny if they were the elusive red cherries.

Less than the browns, actually, since there is no tactile bump (force at the actual operating point is about the same).

for it to be 8-key rollover, the keyboard would have to correctly register any and all combinations of 8 simultaneously depressed keys. just having one combination of 8 keys register correctly is not sufficient.

Yeah, it's kinda ironic that fancier illuminated and/or gaming boards tend to have "cost-cutting matrices" while basic $10 corded MS or Logitech jobs have decent ones...
