    I’m glad to have it. I have to keep my old PS/2 keyboard plugged into that slot so I can get into the BIOS. My USB keyboard isn’t recognized until it’s too late to interrupt the boot process.

      I had the same problem until I learned motherboards tend to prioritize the top usb slots or specific ones for the boot process. Switching to those fixed it for me. Any such luck?

    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.

    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.

        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.

          Your story reminded me of when I set my pc on fire!

          No idea how or what happened but the PSU shot sparks, lit up and tried setting the house on fire. Amazingly everything worked right after replacing the PSU, but the Mobo was the next thing to blow up.

          So while they are indeed resilient af, you’re likely not coming out unscathed if sparks fly.

        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.

    Same as VGA, shit just works, don’t need to worry about drivers or OS. So if your server shits the bed, you don’t need to worry about these things not working so you can can figure what went wrong.

      My mechanical keyboard came with a USB-to-PS/2 adapter, and I use that instead of the USB one. Feels good

        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.

    Went to Disney recently and had a lot of time to wait in line. I found a ton of old tech recycled into decorations in their Star Wars area. I got to explain circuits, hard disks, and old connectors to my kids.

    My keyboard uses PS/2 and although I do have a PS/2 to USB adapter, i prefer using my computers PS/2 port because it means one more USB port can be used for something else.

    30+ years old and it runs flawlessly.

    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.

      That makes sense! The convenience of USB means that this single point of entry is now a critical security risk.

      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!

      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.

        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!

      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?

        It’s the initialisation mode of USB 40Gbps, luckily not something users will have to deal with

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

          This, it’s why I still use the PS2 interface. Full n-key rollover is impossible for me to do without.

            Out of curiosity, what is the practical use of full N-key rollover? I can’t think of many things that require me to press more than maybe five keys at a time.

              Bit of a niche use-case, but I’d like to have it for using my laptop keyboard as a piano keyboard, for basically MIDI input (via VMPK or one of the DAWs with this feature built-in).

              There’s even certain combinations of just 4 keys, which I simply cannot play…

              Used to have these problems when we were children and playing fighting games with my brother with one keyboard or guitar hero clones that need you to press multiple buttons at the same time, that’s the only use case I could think of. I don’t know if there’s any modern software that requires you to mash more than 2 or 3 buttons at the same time

        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.

        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.
