lol it’s on my gaming rig

Sounds more like bore out than like burn out.
So you want to connect your mouse and keyboard, but all your usb slots are taken? I got your back, fam!
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.
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.
Enjoy your 720p analog signal.
Display port is where it is at
For most workflows, especially text, 720p is more than enough.
That said, DisplayPort >>>>> HDMI

Of course it is, but I’m just talking about why these things survive
In a server environment it’s perfect. Have multiple baremetal servers in the rack?
No problem, all you need is a PS/2 + VGA KVM and you can control them easily without fiddling. No protocol handshake, no HDCP in the way.
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.

But just use DisplayPort instead.

Everything in the world is hdmi or DisplayPort. VGA is essentially now a specialty connector used only in data centers.
HDMI has their fees, but DisplayPort doesn’t. Plus at this point implementing analog to digital converters is probably more expensive than just putting DP on it.
VGA is flaky and prone to issues. It doesn’t have a way of reliability relaying information such as display metadata.
IDK man, it would be great if my crash cart or KVM only needed one cable. I can’t wait for USB-C on servers to be everywhere

There is really no reason not too though. Displayport also takes up less space that would be used for cooling or whatever.
The only reason other than compatibility is probably that the screws are nice to have if you hook it up to something permanently like a KVM. Displayport have latches but imo they suck and I usually buy cables without them.
And no DRM bullshit like HDCP getting in the way.
You’ve just gotta dig out the mouse/keyboard combo that came with the Packard Bell you bought in 1996 from some dusty box in the attic / storage room at work
I’m currently using a PS/2 Dell AT101W while I procrastinate fixing my AT Leading Edge DC-2214
I haven’t seen a device with those in a very long time.
I see them at work sometimes.
A device, no. A motherboard? Yup.
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.
My mechanical keyboard came with a USB-to-PS/2 adapter, and I use that instead of the USB one. Feels good
cause its good
Old reliable!
Isn’t the latency lower on ps/2 than usb?
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.
Higher than that, I have a keyboard with 8000hz polling and a mouse with 4000hz polling. Anything over maybe 2k at most is hard to perceive, at least for me
I think a high polling rate matters more with N-key rollover (lots of successive keypress messages in one bunch), which in turn matters for some gaming scenarios.
Afaik PS2 juat injects inpits straight to the CPU
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.
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 differences which would be quite hard to notice. 4000hz keyboard definitely beats PS/2 though.
I actually use a keyboard with that connector with a converter ( to USB ). It works pretty well.
Fyi, I’m using a very old happy hacking keyboard my father gave me
Here’s the picture of the keyboard I found on the Internet:
Control in the right place! I always have to use registry hacks to get caps lock to be Control in Windows.
That’s… odd
Same here, still rocking my $1 Model M 7 years strong now
Model-M from 1992 checking in, with all its PS/2 to USB adapter glory. Works great, and is heavy enough for home defense, removing unwanted fingerprints from walls, and smashing produce.
I used a ps2 mouse until about a year ago. If it ain’t broke…
Aren’t they?
I have not seen one in years. maybe a decade
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.
What show / movie is this meme template from?
Sonic I think? Never watched it but the boots in the bottom picture look like Sonic
Yes, it’s from the Sonic movie. Original
Sonic for sure
Hahaa… laughed at this, checked my computer only to see my keyboard is using this… It didn’t at all bothered me all these years, so… Long live
