Archaeologists Excavate Ancient PS/2 Keyboard and Mouse Ports

Level 1: Grandma's Rotary Phone in the Sandbox

Imagine kids digging in a sandbox and gasping as they brush sand off an old rotary telephone — the kind with the spinning dial — treating it like dinosaur bones, while Grandma watches and mutters, "I used that last Tuesday." The joke is that something perfectly ordinary to one generation looks like a museum piece to the next, and computers age so fast that the "ancient treasure" being dug up here was on every office desk about twenty years ago. It's funny because it's a little bit true, and a little bit insulting to everyone who remembers plugging in the purple one.

Level 2: What You're Looking At

The top panel shows a real archaeological excavation — people kneeling in a dirt pit, scraping centuries of soil off stone foundations. The bottom panel replaces the expected pottery shard with a chunk of an old PC's rear I/O panel:

• PS/2 ports are the round, 6-pin sockets that keyboards and mice used before USB. One port per device, each a fixed shape and color: purple = keyboard, green = mouse.
• USB replaced them because one rectangular port could handle any device, could be plugged in while the computer was running ("hot-plugging"), and didn't care which socket you chose.
• The icons next to each port — a tiny keyboard and a tiny mouse — existed because before the color standard, plugging into the wrong port meant the device simply didn't work until you rebooted.

If you started computing after roughly 2010, you may never have seen these outside a server room. That's the joke's engine: technology you merely stopped seeing gets reclassified, emotionally, as ancient — even though the gap between "everywhere" and "excavation site" was barely fifteen years. Working in tech does this constantly: the build tool you mastered last year is somebody's punchline next year, and the dirt accumulates fast.

Level 3: Stratigraphy of the Beige Era

The bottom panel's photoshopped "artifact" — a purple PS/2 keyboard port and green PS/2 mouse port, complete with their tiny embossed icons, being lovingly brushed free of red dirt — is funnier the more you actually know about the thing being excavated. The PS/2 connector arrived with IBM's Personal System/2 line in 1987, which is also where the name comes from (no, not Sony's console — a fact that has confused at least one generation of juniors). It's a 6-pin mini-DIN carrying a simple synchronous serial protocol, and it ruled desktop input for nearly two decades before USB finished it off.

The color coding itself is a small archaeology lesson. Early PS/2 ports were identical metal rings, and plugging the keyboard into the mouse port — electrically similar, logically incompatible on most boards — produced a machine that booted into silence. The purple/green scheme was standardized in the late-90s PC 97/PC 99 specifications, an initiative pushed by Microsoft to make beige boxes less hostile to humans. Which is precisely why the tiny Bill Gates cameo pasted in the corner of the dig photo is such a good touch: he's the pharaoh whose dynasty's seal is stamped on the artifact. Tutankhamun gets a golden mask; we get color-coded mini-DIN.

The deeper irony the meme trips over — accidentally or not — is that PS/2 isn't entirely dead, and the reasons it survives are deliciously technical. PS/2 keyboards are interrupt-driven rather than polled like USB HID devices, and the interface imposes no rollover limit, so true N-key rollover comes free. No drivers, no USB stack, which is why server boards, BIOS recovery scenarios, and a certain breed of competitive-gaming keyboard purist kept the port alive years past its funeral. The "ancient relic" in the pit would, if wired up, still outperform a cheap USB keyboard in at least one measurable way. Plenty of legacy tech persists like this: not from nostalgia, but because the replacement quietly traded away something the old thing did perfectly.

And of course, the trauma tax: PS/2 was not hot-pluggable. Yank the mouse mid-session and you rebooted, full stop — on some boards you risked a fried keyboard controller fuse. An entire generation learned cable discipline from that single design constraint, the same way archaeologists learn to brush instead of shovel.
