Could be worse, could be that one.
Big keyboard jack, serial for mouse, parallel for printer

Yes, this is where my PC master gaming started.
“do you know what ps/2 ports are?”
“holy cow, PlayStation 2? you must be AT LEAST 25!”
[dying inside intensifies]
IBM sure made naming pretty confusing aren’t they?
Not really? I mean it was a whole thing. OS/2, PS/2, I think maybe some PC/2? I can’t remember. Anyway it was all branded together.
missed opportunity for the mainframes to be “system/2” and not “system/360”
Ps/2 ports predated the PlayStation 2 by years. Sony made naming confusing in this case.
How can ports of a game predate the platform itself? That makes zero sense.

I raise

edit, actually, it might have been on the back…it’s been forever since I touched one

I’ll see your raise, and up it:

Please,

Young whippersnappers.

You kids don’t know how good you have it!

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.
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
Its on the side. You can kind of see it in your picture. I have a C64 within arms reach.
Bonus points if you had a mouse to use with GEOS:

Ooh, I had a serial mouse (9 pin) from Microsoft of all companies, in the 90’s.
Damn good mouse.
I remember a time when they weren’t colour coded…

what the actual hell is that? a port connector for the borg?
It’s a connector for an IBM 7000 series mainframe.
The computer mouse I still use today has a ball in it
When was the last time you cleaned it out?
Earlier this week it stopped going up and down, only side to side. Had to clean some crap off the x-axis wheel.
Good stuff, was imagining a 30 year old mouse with 30 year old crud! 🤮

What kind of connector is this? I remember seeing them on 1970s audio equipment, maybe for mic in?
It’s an AT/ XT keyboard connector.

This reminds me when a mouse was an option not a requirement
still is

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.
And having to pick your IRQ when installing anything into your machine, and the weird bugs that could happen if you mucked it up.
I remember manually programming the cylinders and heads on a hdd into the bios. Kids these days got it easy
I tried to explain these ports to a salesperson at micro center, and they have me the dull cow stare.
I was looking at some PC’s at Best Buy and a salesman came up to try and give me the hard sell. I asked if I could buy the PC without Windows on it for a discount.
“How would you use your computer without Windows on it?”
“I’m going to install Linux”
“What’s that?”
“It’s an operating system”
Blank stare
“Like Windows or OS X…”
Blank Stare
Sigh “I already have a copy of Windows at home”
“Oh! Well I don’t think you can do that, no.”
Yeah well my first computer typed in cuneiform so get off my lawn you kids
I’m this old.

I’m punchcard Fortran old.
An elegant port for a more civilized time
Nothing civilized about no hot plugging. Had to restart the whole damn computer, if the cable was loose or out at startup.
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?
Yes, back when you could use a tube tv as a monitor over RF.
e: mine still works, and I’ve connected my ancient equipment to my newer flat televisions with it.
Old enough

Yeah a 9 pin dsub. Still used widely in industry applications and other Fields. Edit: just saw that these were used for mouse or keyboard input, wth. This is truly old.
