      Yeah but try pressing more than 4 keys at once on the PS2 keyboard and get back to me

      • e8d79@discuss.tchncs.de ⁨8⁩ ⁨months⁩ ago

        That is a limitation of the keyboard not the PS/2. Unlike USB which is limited to 10 simultaneous key presses, PS/2 supports full n-key rollover.

        I think you’re confusing USB and PS/2. USB has (or used to have?) a limit on the number of keys you could press, whereas PS/2 supports n-key rollover.

        Nothing to do with the interface. If your keyboard can only do 4 it means that the manufacturer has cheaped out on diodes and couldn’t even be bothered to stagger the matrix enough to make you not notice.

      USB: Many designs and revisions, none of them perfect

      Nah, USB 3.2 Gen 2x2 SuperSpeed is the best! And it took me only 30 minutes of reading articles and wiki pages to get that information! ^(although I’m not sure what USB4 Gen 3×1 is, but it’s only x1 so can’t be that good, right?^

      I know this is a shitpost, but what’s interesting is that even though USB doesn’t directly interrupt the CPU it’s still faster. USB is able to get the entire packet sent before PS2 even sends one. It’s very interesting. So if you ever see anyone unironically saying there is less latency call them out!

      source
    • dejected_warp_core@lemmy.world ⁨8⁩ ⁨months⁩ ago

      Are PS/2 ports still operating on hardware interrupts these days? I would expect these to be emulated as USB devices at this point, depending on whatever I/O chipset is in play.

      The bit about USB asking the CPU is kinda true? My understanding is that it’s a packet protocol of sorts, so it’s really just writing post-it notes for each button press and leaves them on the CPU’s whiteboard for later.

      source
      • JackbyDev@programming.dev ⁨8⁩ ⁨months⁩ ago

        Yes, it’s true the the USB protocol has to “wait” but it gets the message sent so much faster that it doesn’t matter. Still interesting stuff though!

        I recently bought a motherboard with a N100 processor, that had two 3.0 USB Ports, two 3.1 USB Ports, an HDMI and a DisplayPort. Because of that I was surprised to learn that it had also two PS/2 ports for a keyboard and a mouse.

    If there is a fault in the PS2 device it literally breaks the rest of the computer.

    A little more than 15 years ago I had to fix my PS2 keyboard because it crashed everything. Not even a BSOD, just colors.

      looks nervously at my 3070ti and ibm model m haha so was there any permanent damage or like

      source
      • x00z@lemmy.world ⁨8⁩ ⁨months⁩ ago

        No. It was when I was younger and I smacked the keyboard at some point. The whole computer crashed with random pixels all over the screen. I tried rebooting many times. I came to the conclusion the cable inside of the keyboard must have been slightly disconnected and pushed it further back into it, and my PC worked again.

        Computers are really resilient to permanent damage to be honest. I once dropped a screw into a running computer and it short-circuited with sparks and all. I was still able to boot it, but it was extremely slow. After a few reboots it was back to normal.

        I think it’s because PS2 has very low level support. It’d have to be pretty borked, and there’s not too much to bork, so pretty rare.

      In a server environment it’s perfect. Have multiple baremetal servers in the rack?

        PS/2?

        I’m not completely sure but I’m pretty sure that at least the majority of our servers only have USB and no PS/2 port. And while our servers aren’t very old some of them still have a few years on them.

      I don’t know what server you’re running, but I have never had any issues with USB keyboards. They just work, including in the firmware. No drivers needed. Besides, a proper server motherboard will have IPMI so you can just remote into it.

        I’ve had KVMs that don’t like the ‘fancier’ USB keyboards with NKRO. It would work, but it wouldn’t listen for its own ‘switch to different console’ hotkeys. Reconfiguring the keyboard to run in 6KRO-only mode addressed it, but not every keyboard can be configured that way.

        Isn’t almost any keyboard able to last that long?

        In theory, yes. In reality… not so much. Bluetooth keyboards are a joke for longevity, and a lot of wired keyboards these days just have piss poor build quality.

        I don’t think PS/2 inherently has major advantages over USB but as someone who uses a small PC with few USB ports, I appreciate having a PS/2 port available.

        Usb keyboards can have n-key rollover which let’s you press more buttons simultaneously, whereas PS2 has a hard limit of like 5 or so

      I’ve often thought this about older or less generally useful ports, but then it just keeps coming back to the fact that, if I had the same number of spare ports, plus one more USB that I useD for this keyboard instead of a dedicated PS2 or an old USB 2, I’d be in the same situation but with at least one more useful and fast USB that maybe I might for some reason want to use without my wired keyboard plugged in.

      It makes sense in terms of cost, because the older more narrowly useful port is hopefully cheaper, but otherwise it’s just unnecessary and more limiting than the same overall number of ports where all of them are the most widely useful and fastest possible throughput.

        I did try that but unfortunately it didn’t work on my system. There is also an option for the systemctl reboot command that I haven’t tried yet but plan to next time I need to get into the BIOS. IIRC it’s “–firmware-setup”. It’s supposed to reboot you into the BIOS, but whether it works or not depends on if your hardware supports it.

    We asked our Dell sales guy this question years ago now, when they had been removed one year and quickly added back the next year.

    They are there mostly for government builds, and other places with high security requirements. Usually the requirement is that they need to prevent any unauthorized USB devices from being plugged in. With the PS2 m&k ports they can disable the USB ports entirely in the BIOS.

    Isn’t the latency lower on ps/2 than usb?

    source
    • Pirasp@lemmy.world ⁨8⁩ ⁨months⁩ ago

      Not necessarily, modern having keyboards can operate at upwards of 1khz polling speed. The main difference is, that usb needs polling in the first place, whereas ps/2 is interrupt based.

      That essentially means that ps/2 tells the computer “hey a key was just pressed” instantly and usb waits to be asked whether a key was pressed or not. If the latter is done often enough the difference becomes negligible.

      • FiskFisk33@startrek.website ⁨8⁩ ⁨months⁩ ago

        but the protocol is slow. with high speed usb and fast polling rates, even though ps/2 starts sending instantly, usb will often have had time to poll and send its whole packet before ps/2 has finished sending.

        source
    • drathvedro@lemm.ee ⁨8⁩ ⁨months⁩ ago

      Not necessarily. Even though PS/2 operates with a superior protocol, latency-wise, the clock speed is atrocious, resulting in an effective polling rate of about 1500hz, give or take. We could account that it doesn’t need to wait for request to send keystrokes like USB keyboard do, effectively doubling it even more, but then we’d have to account for whatever delay Super I/O chips introduce and I’m not qualified to talk about that. But, if your keyboard is not from a dollar store shelf then it probably runs on at least 1000hz, at which point we are talking about sub-millisecond difference which would be quite hard to notice. 4000hz keyboard definitely beats PS/2 though.

    NGL I literally still use a PS/2 port for my decent yet extremely old membrane keyboard from circa 2007.

    I meant to upgrade to a customized mechanical keeb a few years back, got a bunch of sample key caps and switches, got really overwhelmed by the choices, and never bought anything permanent.

    In my dream scenario this choice pays off when some fed agency tries to install a hardware keylogger and can’t because I’m the last idiot still using a PS/2 keyboard in 2024.
