Behold, the superior mouse and keyboard interface. The fact that USBslop was allowed to replace everything is a crime against personal computing. Sometimes standards should be left alone.

>The PS/2 interface provides no restriction on key rollover.
>The USB HID keyboard interface requires that it explicitly handle key rollover, with the full HID keyboard class supporting n-key rollover. However, the USB boot keyboard class (designed to allow the BIOS to easily provide a keyboard in the absence of OS USB HID support) only allows 6-key rollover. Some keyboard peripherals support only the latter class, and some OSes may fail to switch to using the full HID keyboard class with a device after boot.

Your stupid laptop still use them.

Oh no, not the 6 keys rollover limit

Anyway

I can't find any motherboards with this connector on a modern AMD socket for less than like 400 dollars. They finally ran out of these little shits and now they're being reserved solely for enthusiast grognard tier boards.

It's over

Try connecting this port without looking and reaching behind your computer. Fuck that port

>>106103897 (OP)
What if I want to plug in two keyboards and two mice

>>106103897 (OP)
I hope I indirectly spawned this thread by shilling PS/2 supremacy on the other thread.

Based, usb = nigger.

>>106104957
>bends 2 pins on the connector

lmao, lol even

>>106103897 (OP)
You're not wrong.

>>106103897 (OP)
>Unplugs
>Plugs back in
Guess you need to restart now

Pros:
- less than 10 ms latency
- green and purple color is rad
Cons:
- everything else

>>106104957
Connecting PS/2 without looking is easy. Whilst USB is close to impossible.

>>106104957
I never had problems with that, they always had a slight flat edge on the top so you know the orientation by feel. USBs will ALWAYS have the "lol wrong flipside" quantum mechanic at play, no matter what you do.
>>106106263

Thanks doc.

>>106106250
Exactly this. Niggers don't know about my interrupt privilege.

>>106106369
isn't interrupt privilige exactly what niggers abuse?

>>106106315
The real issue with USB is it requires absolutely perfect alignment or it will not go in and it has zero self centering either. Other ports give you some tactile feedback, but USB gives you nothing, so you are fumbling around with no idea where the plug is in relation to the port. A lot of people center in on USBs symmetrical nature as the main issue with USB, but really the alignment issue is the main problem, and the symmetry just makes it worse.

>>106106413
Good point.

>>106103897 (OP)
ughhhhh it's just soooo..... inconvenient compared to USB

USB is literally the Borg of interfaces.
>all ports must be assimilated
>everything must be the same interface
>resistance is futile

>>106104957
Try doing that with USB.

>>106108467
Not just ports. All internal components must become external USB devices.

>>106103948
6 keys is plenty if it's any combination of keys.

did you know your usb mouse/keyboard can be polled more often than ps/2 can send interrupts? so much for the superior standard

>>106109328
Doesn't matter unless you type faster than PS/2 can interrupt. Latency is still worse.

>>106104957
i'm not plugging a usb-a in blind either, it takes me three tries even when i'm looking at it.

>>106109328
cool but polling still stinks

>>106105188
>>106104751

>>106103897 (OP)
it crashed your computer when you plugged or unplugged them though

>>106109502
Use case for that?

>>106104025
>mouse/keyboard died
that only happens to modern chinkshit, which almost never uses PS/2

>>106106196
no. as long as you booted with the device plugged in, you can replug it all you want.

>>106109291
It's already 3 keys just pressing wasd and crouch

>>106109613
That still leaves more keys than you can comfortably press with a single had at the same time. Like I said it's only a problem if specific combinations of keys don't work, like if you hold shift for sprint, w/a to run diagonally and then try to hit space to jump but it won't register. Some keyboards are worse than others in that regard.

>>106105220
>usb = nigger
Truly. USB keyboards have given me so many problems I basically refuse to buy or use one at this point.
>can't enter BIOS half the time
>have to replug it when it stops working after waking
>sometimes not even replugging helps, have to power cycle entire system
>wireless receiver lagging to fuck at random times
>cable detaches itself because it's a feature
Finally got back on a PS/2 keyboard and couldn't be happier - shit just fucking w o r k s . Never going back to USB if I can help it.

>>106109328
When the CPU decides polling is unprioritized then it will be no matter the max speed. Meanwhile PS/2 will interrupt CPU and CPU must handle it.

>>106109328
USB has lag spikes. PS/2 has guaranteed latency.

>>106103948
i have NKRO on my USB keyboard
it's not USB's fault that pajeets developing office slop keyboards never take them off boot mode which is limited to 6KRO

>>106103897 (OP)
funny story today
i couldn't upgrade my windows 10 installation without uninstalling all drivers because apparently the drivers cause a BSOD when installing windows 11 by trying to write to ROM
after i uninstalled alll my drivers I fucking forgot to reinstall the input ones before restarting (but i remembered gpu drivers lmao), so i had to drive to 3 different thrift stores to find a ps/2 keyboard so i could restart the installation process. it only cost 3 bucks
somehow it fucking worked (thanks chatgpt)

Can't wait to plug my monitor via USB into my graphics card connected via USB to the motherboard with USB power supply

>>106104025
>>mouse/keyboard died
>>you must reboot your pc to after connecting a new mouse/keyboard
y tho

>>106109487
That's just USB, isn't it?

>>106104751
Are they becoming less common? My b360m bazooka has one but my new motherboard doesn't. However my new mobo is a micro atx.

>>106104025
>>106109840
I just swapped 2 very different PS/2 keyboards back and forth and they both just worked. So it seems that as long as you boot from cold with a keyboard plugged in, you can replug and even swap between different keyboards (and >>106104025 is a faggot).

>>106109837
That's already a thing on laptops.

>>106103897 (OP)
>disconnect

PS/2 is the relic of the past. Let it go

A nothing burger in practice, you are much much slower. It is pure placebo.

>>106103897 (OP)
Liking obsolete tech is such a brown person thing. CRT, PS/2, what's next, IDE and dial-up?

>>106111559
Sounds pretty based

>>106109826
cute legs

>>106106257
>>106108574
You idiots. It plugs in perfectly on the 3rd-5th try. Every time. No pin bending or needing to get within 1° of rotation for it to work.

>>106103897 (OP)
I think it's better than USB but it needs ground surge protection so that it's hotpluggable

>>106103897 (OP)
>slop
That word should be banned, I cringe for the poster every time I see it.

>>106111602
Nothing wrong with IDE, and dialup is based just for the extra layer of privacy it adds if you now your way around it.

>limited to 200hz polling on the mouse
no thanks
is it worth plugging in a ps/2 compatible usb keyboard though? i got picrel and it came with a usb to ps/2 adapter, am i gonna see any benefits on an am4 motherbiard or would i just be running usb in disguise

>>106113983
If the adapter was correctly designed, there should't be a difference.

>>106113983
there is no polling in ps/2

>>106104751
My assrock am4 board has a single keyboard/mouse PS/2 port.
