Welcome to Programmer Humor!
This is a place where you can post jokes, memes, humor, etc. related to programming!
For sharing awful code theres also Programming Horror.

I’ll see your raise, and up it:
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.
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
Big keyboard jack, serial for mouse, parallel for printer
Don't forget the serial input for gamepads and joysticks in the dedicated sound board for some reason
Except that wasn't a serial port, it was midi, and the reason it was on the sound card was because the input was analog.
Your joystick was just two fancy potentiometers, and your soundcard decoded the voltage on the middle legs into a position.
Soundcards handled joysticks because they had the fastest ADCs.
They didn't even use an ADC. They used 555 timers to produce a pulse. They measured the length of the pulse to determine the potentiometer position. Since there are 4 analog inputs, they typically used the 558 timer which is the quad version of the 555.
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.
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.
In my day, the RJ-11 jack was for connecting the keyboard, not the phone line.
The time of the classic "Keyboard missing. Press F1 to continue."
You know that thing that you don't have? You should press buttons on it.
Fuck you computer....
Way back, there were some rare keyboard / motherboard combinations where the motherboard couldn't detect there was a keyboard attached unless a key was pressed on it. That message was for those people with those combinations.
You pressed F1 and the computer would be like "my bad, there is a keyboard there, thanks for your help", or rather it would just shut up and boot.
The message could have been different but it had to fit in a small amount of BIOS ROM, so we got stuck with the one that covered all the bases the best, and unfortunately, most people who saw it didn't actually have a keyboard plugged in, thus, irony.
Bitch
please.
(Kidding, you’re not a bitch and this isn’t a contest. But if it was…)
Fairly certain my first computer used something like this for the keyboard. I did not have a mouse.
"do you know what ps/2 ports are?"
"holy cow, PlayStation 2? you must be AT LEAST 25!"
[dying inside intensifies]
Back in my day they weren't color coded.
That's because color hadn't been invented yet and therefore people could only see in black and white. That's why old shows don't have color.
Look at you with your fancy ps/2 keyboard port. Where's my AT port and 9 pin serial mouse.
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 ;)
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)
You guys had keyboards?
But the keyboard is the computer, mice haven’t been invented yet and where do I plug the tape deck in?
Yeah well my first computer typed in cuneiform so get off my lawn you kids
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.
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.
