lol PS/2 ports are the newer ones. There were larger AT ports and ADB ports in addition to the 25-pin(!) LPT port (printer mostly) and COM ports (random peripherals including early mice, pre ps/2)
These aren’t old. I had one in the early 2010s, it was handed down by a relative because my parents were poor.

Bitch
please.
(Kidding, you’re not a bitch and this isn’t a contest. But if it was…)
I don’t recognize this… Is it some sort of RF switch for connecting a computer or game system to a TV while still passing through the antenna signal? Why does it have two cables coming out the side?

Old enough
“hey guys–”
JOYSTICK PORT!
“not what I’m called.”
I got that reference. Fuck, I’m old.
Please explain? I get that the chubby bird is speaking assembly, but I’m sure there’s more to it than that?
PS2 keyboards use interrupts rather than polling in USB, meaning every time a key is pressed the CPU stops what its doing to process it.
I’m wondering, is it still the case for mobos with Super IO?
Super IO does still use interrupts as far as I know. The PS/2 protocol is interrupt-driven, so it’s not possible to use a PS/2 keyboard or mouse without interrupts.
Cool! I had no idea it was deeper than just a physical interface change.
I didn’t know the PS2 had a keyboard
I know you’re probably being facetious… but the PS/2 port is what’s shown in the OP image.
that said the Playstation 2 had USB ports, you could just plug a regular keyboard into it
Keyboard slows down the CPU because it gets priority over whatever the CPU is working on so the keyboard could cause your system to lag.
Back then all we had was single core CPUs.

This old
Look at you with your fancy ps/2 keyboard port. Where’s my AT port and 9 pin serial mouse.

Where’s my altair with front panel register switches
Ok, I’m not that old either, but still
if I remember correctly my first PC had the bigger DIN connector for the keyboard and a DSUB9 for the mouse. Guess I’m old ;)
Same. I remember needing converters for these newfangled PS/2 connectors. Then again, I am old enough that I remember why floppies were called floppies, and used tape for more than just backup. And hard drives being as big as a shoe box and with less storage than you now have as CPU caches.
Was the tape to cover the write protect notch on the floppy?
Nah, we got them fancy sliding tabs on those. I was talking about loading programs from tape LOL.
Um , b4 that there were serial mice on my tandy
I thought I was hot shit when I got a tape drive for my Tandy that worked about 60% of the time
Like 30 something?
Oh I first learned to type by typing “The quick brown fox jumps over the lazy dogs” over and over on a wireless keyboard.
Called a typewriter.
Box o’ “useless” cables gang represent
In my day, the RJ-11 jack was for connecting the keyboard, not the phone line.
Okay that’s something I had no idea about hahaha
The first three Macs had this jack in the front for the keyboard and a PC-like serial port in the back for the mouse. With the Mac SE and II, the switched to ADB, which looked like a PS/2 port, but you could daisy chain your mouse, keyboard, and other inputs like tablets or joysticks all into one jack in the back of the computer.

The port looks similar - both are mini-DIN - but ADB has four pins while PS/2 has six.
ADB was first introduced in 1986 on the Apple IIgs, and later was used in all Macs from the SE until the iMac. For the first few years there were two ADB ports, but in 1990 (maybe starting with the Mac IIsi?) they reduced it to one and started shipping keyboards with ports to daisy chain the mouse from.
You got a mouse?
Is that what that icon is that isn’t a teletype?
