is PS/2 really the better keyboard interface ?

[KenjiUmino]

now i am really confused after reading THIS

 

this guy points out that PS/2 has some advantages over USB such as natively supporting full key rollover.

 

but ALL PS/2 keyboards i had only allowed a rather limited number of keys to be pressed and recognised at the same time.

 

i always thought this is BECAUSE of a limitation of the PS/2 interface in the first place.

 

i remember with some computer/keyboarrd combinations the built in speaker even started beeping when too many keys have been pressed down at once

 

if what he wrote is true it means i had been wrong all the time.

 

or was it just because i never had a really good PS/2 keyboard? i mean, i had a lot of cheap keyboards but even my old IBM keyboard had this issue and some cherry boards i had after that.

 

i still keep a cherry PS/2 keyboard around as a backup/failsafe for certain critical situations (like getting into BIOS on mainboards that refuse to detect USB keyboards for whatever reason) and that one also has no full rollover AFAIK

 

can someone confirm any of that ?

that post is from 2008 usb 3 has fixed a lot of the issues with key roll over. 

also the post says

"

• Supports full NKRO.

"

not all keyboards have nkro but ps2 has the ability to do it.

so they just did not bother to implement it on the PS/2 keyboards i had ? what a shame
