I wanna say my first PC that I used a was an Amiga with similar i/o as this: I remember that mouse connector vividly.

ADB was superior.

I used a PS/2 keyboard until like 2 years ago. At some point over 10 years ago I decided that I'd only replace it when it died. But it wasn't very good at dying, and 2years ago I finally had enough of the cheap rubbery switches and the fact that I couldn't press enough keys at the same time

These little overclockable bastards ...

You guys have 6 pins? I only have 5!

WDYM old, it's still being used from time to time. For fucky ~~BIOS~~ UEFI's and for easy NKRO without HID report fuckery
