[@sinbrown1501]

Yes, you're right! PS/2 ports work differently from USB ports. PS/2 devices (keyboards and mice) communicate directly with the CPU through interrupts, which means they don't rely on the same polling process as USB devices. USB devices require the CPU to periodically check for input, which uses a small amount of processing power. On the other hand, PS/2 devices send interrupts only when there's actual input, making them slightly more efficient. While the performance difference is typically minimal, especially with modern CPUs, using PS/2 can technically free up a bit of CPU resources compared to USB. However, most people don't notice this difference in everyday use, as USB has become the standard due to its convenience and widespread compatibility.

They're still useful within the niche of high security computing. The USB protocol relies on software to translate signals coming in from the port which, thanks to how serial data works, means that that software will just ignore any data it does not understand. This means that any USB device can send any kind of data it is programmed to do so along the wire, or serve as a keylogger, with only a few modifications that are undetectable without a complete disassembly of the device and painstaking inspection under a microscope to reveal the tampering.

[@spartanturtle590]

Hay, stop making me feel old.

[@th3thrilld3m0n]

They still can be quicker than USB sometimes. These ports send data to the computer, rather than the computer asking for data through USB.

[@theseabass]

In 2011 I was pretty sad when I upgraded to a new motherboard platform, and I had to part ways with the PS/2 port for the first time. At the time I was worried about the issues with USB not being able to register as many keys being held down simultaneously. I still would use PS/2 if I had the port/nice keyboard with that connector.

[@pipolwes000]

I remember the old days when you had to hard boil an egg to refill the mouse when the old roller ball went bad, and the Internet screamed at you when you tried to connect. Good times.

[@stormthrush37]

Usually what I remember going bad wasn't the mouse balls themselves but rather the two rollers the ball moved got covered in gunk, and they had to be cleaned off to get the mouse working right again.

[@mendodave]

@@rfichokeofdestinymy first PC had a 9 pin serial and 25 pin parallel. No PS2 ports until later. I still remember when USB A was coming out, 2 motherboards for me later, and what a big deal that was going to be. Heck they talked about it on the evening news at KPIX.

[@1windozesuk]

Yes, the fat round din for the keyboard and a 9-pin Dsub for the mouse (with my CGA monitor!

[@yannieboi]

I always thought I was just stupid. Didn’t know you had to reboot everytime.

[@rendytiakurniawan]

It still works for Low budget PC build. Some budget motherboards don't offer many USB ports on the back panel, and those ports often get taken up by things like Wi-Fi dongles, Bluetooth dongles, etc. If your mouse and keyboard are also USB, you'll run out of ports quickly. So, it's better to use a PS2 mouse and keyboard to free up 1-2 USB slots for things like data transfer.

[@Groza_Dallocort]

Or you can get a USB hub that have it's own power source and problem solved

[@___15]

pci usb boards are extremely cheap.

[@JasonGroom]

If i recall, they also can register movement/key presses faster than USB making them better for gaming as well

[@LilacMonarch]

also it has no limit to how many keypresses it can register at once. you can press all of them at the samd time and it'll all register. not that it's reqlly necessary but it's a fun fact

[@jupiterjones3789]

Technically true, but USB asks Your devices 10.000 times per second if they have new information for them.

[@gabrielandy9272]

@@LilacMonarch the limit thing depend on the developer not much on the port. you could find keyboards back then that did not support more than 8 or 9 keys, i had a few of those that had problems playing some music games, they are very cheap. nowdays you have to buy specificially a keyboard that has support for more keys if you want, called n-key rollover, because they optmized and know the average keys people use and just add a few more above it to be safe.

[@Mashed177]

I have one on my pc and still use it! I have an old mechanical keyboard that I’ve never bothered to upgrade, so even though my pc is up to date (it’s got a Ryzen 4070) I still use those old ports.

[@Shwopers]

this brings back memories i once had my favorite keyboard, and i was gonna play on my own pc, but it didn't have the keyboard port, so i just sat is sadness for 5 minutes, before searching the entire house for a keyboard with usb that no one was currently using. Wild.

[@aayushpawar9937]

Ngl these were somehow the most satisfying port plugins out there. It just felt good

[@noaht5654]

It's also very useful for response time data collection. These ports are preferred over USBs. Somehow, the data from these ports is immediately collected whereas a USB input may wait for a complete cycle from the processor to be collected.

[@Crazmuss]

>Somehow PS/2 device actively send input, USB device has to be polled by OS.

The evolution of ports on computers are amazing to the point it became wireless without the use of the ports at all like saying,” I’m too good for you”

[@bland9876]

Why do you need them to be wireless if your never going to move them anyway? Then you have to deal with charging them which is a pain in the ass.

​@@bland9876because so e people are stupid

@@bland9876 For keyboards, I agree. For mice, wireless is pretty much the standard for gaming and has a few minor advantages. And if you're into headsets, wireless is unbelievably nice, not having to worry about tugging or a cable wearing down

[@ChucksBasix]

He forgot to mention that the PS/2 ports had fuses on the board that would blow on occasion if you tried to hotplug the devices. Thus rendering the port useless but saving your board.

[@daddy_shenron]

bro, i actually remember those as i was a kid, and to understand what they do was a miracle for me as a kid

[@Antonismi]

You can also get a PS/2 - USB adapter, so it should work on all USB peripherals as well. Saves you some ports.

[@jlinkpro]

Now teach us about the ol' AT port. Back in my day, thats what we used... back when floppy disks were floppy.

[@gmcdon]

I’m a fire alarm engineer, I can think of at least one fire panel off the top of my head that uses PS2 ports for keyboard access which allows us to work in certain menus. A complete pain in the bum but certainly a clever way of doing it when the panels were installed 20 years ago.

[@redneckcoder]

Heh. Ps/2 was the new fangled interface. My first computer the keyboard used an AT connector and a serial mouse (9 pin serial port, just like we used for our modems).

[@ZENTRON-RBX]
