N-key rollover test.

They must have some crazy matrix routing in that Chicony KB-5312.
Now I'm wondering whether I should really toss that one.

Max: 8

I actually did manage to get zero once. Haven't been able to reproduce it, but it was pretty hilarious.

[zwmalone]

Max and typical mean nothing.  Post the lowest.  So in this case, you have a zero key rollover 'board...

Typical means something if I can reproduce it every time (which I can).

ABS M1 USB on vista

shift + colon, zero key wont work.

It does weird **** like w+d and e key wont work. Awfully annoying.

Also I can do stuff like holding "up arrow" and "right arrow", then hold down wasd, when I let go of the arrow keys, they keep registering.

[keyb_gr]

WDE not working would be normal for an IBM-style matrix.

Shift + colon + 0? Would that be Shift + period (= colon) + num row 0 or Shift + numpad decimal + numpad 0? You can do some funny stuff with the numpad, as Shift will toggle the meaning of keys (i.e. if you have num lock on, Shift + numpad 0 gives Ins). The keypress detection script tends to be fooled if you press or release Shift while some numpad keys are active.

That arrow key stuff is really weird though, my G80-3000 here releases keys properly.

Sorry Ray, Sorry Wellster.  I own more than a few legendary piece of crap keyboards myself.  (that is, they're legendary for being pieces of crap)

[microsoft windows]

Ever seen these?

After having these inflicted upon me at work, they have attained the Legendary Crap status. I'm not too picky about rubber domes myself as I use them on some of my computers, but this one is a low end one. No re-enforcing brackets on any key except the spacebar. The keys stick and feel terrible. They're just crappy pieces of plastic probably made of recycled tires.

[itlnstln]

Those Dells are the suck.  The newer ones were a little better.  Dell is now shipping a scissor-switch 'boards with their new business systems which are actually fairly nice.

[d2v]

MINIMUM score is what you want to report.  Maximum keys registered doesn't tell you much since most keyboards can register 6 keys maximum.

Also DO NOT USE THE TEST in the OP. It doesn't register arrow keys. Wish iMav were around to change the link to THE BETTER TEST ------>>>> http://random.xem.us/rollover.html

Try squashing ASX. If you pass you just beat the venerable IBM Model M.

For 6-key bragging rights try CTRL-QWAZX.

I tried ASX, the TVS gold fails to register X, stopping at AS instead.

On the other hand, the MS NEK4000 passes ASX just fine. No keys appear in notepad when I do Ctrl-QWAZX.

I paid a price of approx. 28 USD for that board. Not bad for a blue cherry board with decent construction.

żQué?

[AndrewZorn]

my G15 gets 6 with any combination I try (except the arrow key thing that another test is able to show).  i hope my on-the-way non-NKRO Filco can come close to this, or that it won't matter whatever the application of it.

[maxlugar]

I paid a price of approx. 28 USD for that board. Not bad for a blue cherry board with decent construction.

Do you really feel the TVS gold has decent construction?

Also, does it use genuine Cherry MX Blue key switches or copies?

My experience with Blue Cherry key switches is limited to the Das (which I promptly returned for a refund) and the Filco FKBN104MC/EB with plate mounted switches, the famous Filco texture coating, and true NKRO using the ps/2 connection. (no transposition problems so far)

I briefly typed on a TVS Gold owned by a contract developer who brought it over from India and I have to tell you, I was not impressed.  It seemed like I had to hit each key directly on-center to get it to register.  Although the key presses were clicky, it didn't sound like my Filco which is why I ask whether or not the TVS uses genuine Cherry switches or knock-offs.  I guess the difference in sound and feel could also be attributed to the metal plate mounting of the switches in the Filco vs. PCB mounting in the TVS.

Wellington will be able to answer all these questions and more when his bright and shiny TVS Gol  d keyboard arrives!

[timw4mail]

You'd be surprised how much feel is dependent on the keycaps, and not the switches. Most likely, the TVS Gold has really cheap keycaps.

[maxlugar]

You may be right.  I didn't want to admit this to Welly, but just this morning I asked one of the managers from our off-shore Indian division to buy a TVS Gold for me and bring it back when he returns to the US in a couple of months.

For 30 bucks, it does add some kish value to my collection.  I mean it's not like dropping $130 for a das and being disappointed.  I'm quite happy with my Filco when I get the whim to type on Blue Cherries.

The previous version of TVS Gold had only PS/2 option, and it had loose keycaps - due to really thin walls around the + shaped switch mount.
The new USB version has no problems with keycaps, they seem to have increased the wall thickness to take care of the wobbly keycaps.
Also, the switches are original blue cherry, I'll upload some photos later today.

Don't dis the 6600... well that much.

It's not a bad board-- decent switches at least-- in an ugly case and an awkward layout.

Hey man, I own a DSI ASK-6600U and I think it's a great keyboard, especially for the money.  I like the way it looks - the lettering on mine is perfect.  I also like the layout because my main driver is an 84-key PC AT Model F.  I took some pics of the key switch and controller for Welly.  It actually has better performance stats than the much hyped Filco Zero.  If I could just get rid of that annoying ringing soud...

I also love the fact that the key switches are ALPS branded simplified type 1s and therefore not technically Fukkas.  Although practically, they are Fukkas.

If you ask Santa Claus for a Blue Cherry keyboard for Christmas, insist on a Filco FKBN104NC/EB or one of Filco 10 keyless Blue Cherry keyboards.

The das left a bad taste in my mouth for Blue Cherries, and I wasn't immediately blown away by the Filco, but it has really grown on me.  The light clicks are so addicting, I have been carrying my Filco back and forth between work and my home office.  That's the definition of insanity - or at the very least, a sign of an obsessive-compulsive disorder  :crazy:

[Hak Foo]

Hey man, I own a DSI ASK-6600U and I think it's a great keyboard, especially for the money.

It is generally competent... it's just there's a bunch of "zero-cost changes" I'd make.  Like a M-style backspace, and about 1.5cm taller rear feet.

 I like the way it looks - the lettering on mine is perfect.

On mine, S and X are way off from the others.

If I could just get rid of that annoying ringing soud...

 Definitely.  I've been on buckling springs for years, and the family complains regarding the noise.  It seems to have reduced a bit.

Although practically, they are Fukkas.

Do we look for reasons to say Fukka or is it just me?

If you ask Santa Claus for a Blue Cherry keyboard for Christmas, insist on a Filco FKBN104NC/EB or one of Filco 10 keyless Blue Cherry keyboards.

I want the G80-3000.  It's got the best potential for parts swaps with other Cherry products, plus I like the slab look.

That's the definition of insanity - or at the very least, a sign of an obsessive-compulsive disorder  :crazy:

I just stuck a 1391401 at my desk and had done with.

[roaduck]

Keyboard - IBM 1391406 - UK 102 key model M - no back label - early nineties? The interface was native PS/2 I/O.

The N-key rollover test - 4 keys accepted - asdf

This is fine for me because I don`t game and I can`t touch type yet.

[AndrewZorn]

is it normal to always have the keypresses in the same order
i mean i switch hands and everything but its always the same
if the keyboard were 100% accurate this would be statistically unlikely

xraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraraxraxraxraxraxraxraxra

[AndrewZorn]

still on the G15 actually
but once those come in i will try
i was just surprised that even a mere human's attempt at simultaneous keypresses was good enough to get it every time

[NOMiS]

Filco Majestouch Tenkeyless Tactile Touch (FKBN87M/EB)
Interface: PS/2
Operating System: VistaU
Max keys accepted: It will accept all the keys I press, I've been over 50 (using keyscan). But if I go over 30 or so (not sure on the amount) it will show on keyscan that they're still pressed. Not sure whats the deal. If I got a lot pressed still and I press more it seems to **** up with OS shortcuts. I can easily press 25 with no problems though.

xraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraxraraxraxraxraxraxraxraxra

note that A X R are in left-to-right order across the board (assuming qwerty layout)

most likely that's the order the key matrix is being scanned in

[AndrewZorn]

initial testing shows hhkb pro2 at 6 every time (success!) and filco brown 104 at 2-4max (awwwwwwww) its the non-nkro version but i still expected better oh well

[AndrewZorn]

Has anyone ever heard of the NKRO test which has you type

THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG

...with BOTH shift keys held down?
I never had, and my HHKB got every letter, but I looked on Google and apparently most boards skip letters and it is a somewhat popular test.

On my integrated laptop keyboard, for instance:
H QUCK BW FX UMP V H LZY D

(this is all in Colemak by the way so the letters it 'actually' skipped may be different, but the point remains)

Need to try it on my non-NKRO Filco.

I don't really know if I would consider it a design flaw to have problems when both of the keys meant to only be used one at a time are held down (if that is the ONLY rollover problem, that is).  I'm all for hypothetical situations and success, but if my keyboard WAS true NKRO but failed this test I don't think I would care.
Still odd that 2 modifiers + 1 actual 'key' at a time would cause such horrible results.

[alpslover]

I'm all for hypothetical situations and success, but if my keyboard WAS true NKRO but failed this test I don't think I would care.

if your true nkro keyboard failed this test, then it is not, by definition, true nkro.  i think i'd care because i'd wonder what other key combinations don't work on a keyboard that was supposedly nkro, and i'd wonder why i paid extra for functionality that wasn't actually there.

[AndrewZorn]

okay maybe that is fair
but i am 1 for 1 anyway

[itlnstln]

Need to try it on my non-NKRO Filco.

Here you go:
 

HE QUIC BROWN OX UMP OVER HE Z OG

This was on my 2KRO Filco (QWERTY).

[AndrewZorn]

not bad i guess
thanks

[itlnstln]

Blue Cherry Filco NKRO QWERTY. I never was any good with that right shift key - I find the pinky extension too far.

You misspelled "FPX."  You might want to try the test again.

[itlnstln]

I am not sure if that's the point or if it's supposed to be an "easy" way to look for rollover problems.  That said, you're right, anything using both Shift keys would be an unlikely combination.

[AndrewZorn]

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

i dont think its really a bragging-rights test (but if your filco doesnt get it, then it is, because my dip-switched rubber domes do) but it is interesting how two modifiers and a single key can mess it up so bad.

on the new test,

HHKB Pro 2 - QWASZX+Ctrl+Shift+Alt (9 total)
EDIT okay so printscreen worked and still gave me 9 but it wasn't the right keys (>6 the hhkb prioritizes the newest one and throws out the old)
so no image

[NOMiS]

Did I beat the test?

Well, if "hjk" only prints "hj", the keyboard is only 2-kro. Sad but true.

[AndrewZorn]

so are you guys pushing printscreen at the end?  that IS a key...
makes my 9kro turn to 8 in the actual screenshot because of the way the hhkb will interrupt to allow it

[Rajagra]

...with BOTH shift keys held down?
I never had, and my HHKB got every letter, but I looked on Google and apparently most boards skip letters and it is a somewhat popular test.

That test can pick up [strike]two[/strike] three kinds of problem:

• Non n-key rollover boards where the matrix has both Shifts on the same row or column - may lose many keys;
• ++Non n-key rollover boards where the matrix has Shifts on different rows and columns - may lose two keys;
• 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.)

My DAS III and Realforce 87U pass the test.
I suspect the IBM model M will fail - I've noted before that its matrix design can't really handle both control keys being held at once.

Edit> Confirmed. IBM 1391406 (of 1992) gives:

• THE QUIK BROWN FO UPS OER THE LAY DO (Using Colemak.)
• HE QUIK BROWN FO JUPS OER HE LA DOG (Using QWERTY.)

[JaccoW]

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

So six keys + modifier keys.
