This is the port that was on PCs (not Macs) to plug in keyboards and mice, before USB or wireless.

I’m actually even older than these ports, but figured it’d be more recognizable. 😅

Here’s the Apple Macintosh ports of that era.

This standard for PC is early to mid 90's when ATX became common. Before ATX, there was the AT standard which had the big DIN connectors for keyboard and a DB9 serial port for mouse (sometimes the serial port was a separate ISA card). Dell started coloring the mini DIN connectors in the mid 90s

It was actually Compaq that popularized this color coding standard, even though it was specified by IBM in 1987. Dell and gateway followed suit shortly thereafter.
