Fairly certain my first computer used something like this for the keyboard. I did not have a mouse.

These little overclockable bastards ...

This belongs on a sound card for some reason!!

Many professional gamers still depend on them because they have lower latency than USB.
wrote last edited by [email protected]That's a myth that should die out. It used to be true, decades ago, but not anymore.
The PS/2 protocol interrupts the CPU and sends a packet. USB has the CPU poll the connection and then gets the packet. However, the polling and clock rate of USB is so high that it can hit it several times before the PS/2 is done transmitting a single packet.
NKRO is also no longer an issue in newer USB versions. You have to get a more expensive keyboard to make it work--cost of all the diodes adds up--but that was just as true of PS/2.
Here's a Ben Eater video that goes over the details with an oscilloscope: https://www.youtube.com/watch?v=wdgULBpRoXk

Big keyboard jack, serial for mouse, parallel for printer
Yes, this is where my PC master gaming started.

I didn't switch to a USB optical/laser mouse until 2014
You must like cleaning balls.

I’ll see your raise, and up it:
Please,

Typed! Back in my day we just got a wire that you had to lick in binary to tell the computer what to do.
A wire!? We just got raw sand and had to scratch out a calculation ourselves.

Please,
I always see those videos where people give kids a walkman or a rotary phone and ask them to figure out what it is or how it works. I'm imagining some medieval merchant handing me an abacus and laughing because I can't figure it out.

PS/2 isn't vintage. I'm still using an adapter to connect my Microsoft Natural keyboard through USB.
Oh, wait...

My buddy still has one of those in his garage.

I used a PS/2 keyboard until like 2 years ago. At some point over 10 years ago I decided that I'd only replace it when it died. But it wasn't very good at dying, and 2years ago I finally had enough of the cheap rubbery switches and the fact that I couldn't press enough keys at the same time

It's little endian, so the beads on the far right are used to outnumber the big endian beads at the top on the woke left. After several computations, the middle section is just gone

I'm still using that mouse, with a 9-pin to ps2 and a ps2 to usb
there must be some noticeable latency on that

I did have a converter from this to a ps/2 connection when I got a newer computer.

Don't forget the serial input for gamepads and joysticks in the dedicated sound board for some reason
