The pic above in this thread says "only supports PS/2 interface." However, the box for the USB KR-6820-E also claims anti-ghosting.

Jeffrey, can you please spell out explicitly what the KR-6820-E USB anti-ghosting capablity is, and highlight the differences with the KR-6820-E PS/2 version? I'd be interested whether i Rocks has any plan to provide an USB driver to provide enhanced anti-ghosting and n-key rollover?

(Me tries to maintain a bland expression while asking such a question.)

I'll add too this thread a photo of the USB box presently.

the text says 'anti-ghosting' for up to 11 keys, but in the very first diagram it clearly shows a block of 16 keys in orange.

i think any keyboard labeled as a 'gaming' keyboard should have n-key rollover.

Highlighting working blocks of keys is helpful but an explaination about what's going on would be nice.

I think there is only one version.  You have to stick one of those purple USB to PS/2 adapters on it to get that N-key stuff I guess.

From Chimera's review.


Obviously a test that would have worked better outside the manufacturers orange areas would be a double-fist from the center.  I don't know how big everyone's fists are, but I can manage to make two that cover nearly the whole alpha area without hitting tab/caps/alt/space/enter/etc and might even drag in a few numerics.  Maybe also one fist on alpha and one on the keypad.  

It becomes decreasingly likely that rollover can be spoofed as you create a greater concentric area of keys in the test, I'd imagine.

its nice to see that level of honesty,
but i really wonder,
would it cost THAT MUCH MORE to have built it with true NKRO, and then just be able to advertise that everything works?
